Base System Description

oXigen is the Slot.it digital racing system for slot cars (digital means that you can drive more than one car per lane, where cars may change lane in designated areas, whereas analog systems are tied to one car per lane with no changeovers).

It is a wireless system allowing digital slot racing with up of 20 cars on the same track.

Chipped cars may run on analog, oXigen, Hornby SSD or Carrera D132 systems.

The oXigen system (from now on “O2�) is based on the following devices: 1. a controller which can either be 1. Any SCP-1 or SCP-2 equipped with oXigen digital cartridge 2. SCP-3 3. Scalextric ARC wireless (C8438) controller with appropriate firmware 2. an oXigen digital chip intalled in the car 3. a lane changer compatible with oXigen: either 1. Slot.it XLC or XXLC lane changer 2. any Scalextric Digital lane changer 3. Carrera LC, Ninco LC or custom made mechanism equipped with oXigen Lane Changer driver 4. a PC 2.4GHz Rx/Tx USB device, knwn as oXigen 'dongle'.

Track To run, O2 needs a constant DC power on the rails, pole (+) on the right side of the car facing forward.

Quick and dirty trick: are you eager to run an oXigen chipped car on an analog track? Leave everything as it is and make sure your track is powered. Plug your analog controller in and keep the trigger pressed: this gives full power to the track, which is all an oXigen chipped car needs to wake up. Now you can drive your oXigen chipped model like an analog car on an analog track, using the oXigen controller of course.

Starting from a standard analog slot track, all you need is an adapter to bring power to the rail. In general, a simple cable with two bananas, and a fuse (highly recommended - fast switching, 6A)will do the job. This is necessary for all lanes where you want to run O2 cars. That's all there is to do: remove the cable, and you're back to analog traditional racing. You can run digital on some lanes, and leave the other ones as analog.

O2 cars can run on tracks powered by Hornby, Ninco, or Carrera digital bases. In case of Hornby base, an additional 'bridge' may have to be installed inside the car, depending on what O2 chip you are using.

NOTE:

power supply polarity on Carrera track may be inverted compared to the generally accepted standard, which is (+) on the right, (-) on the left. Considering this, during the installation of the chip on the car, it might be needed to invert the position of the two cables on the pick-up of the O2 cars or solder the wires on the bridge rectified power pads of chip type 2. Please read the relevant section.

A Scalextric Sport track can as well be reversibly turned into an oXigen compatible one by means of a custom a 3,5mm male jack as described below.

Inside each male jack plug, diameter 3.5mm, create a short-circuit between pins number 2 and 3. Once this jack is plugged into the Hornby's power base, full power will be given to the rails making it hence suitable for O2 system. A best practice would be to place a fuse there as well... We've noticed that it is easy to forget that rails are live, which means that if you carry one any work on the track, screwdrivers etc. can easily short them. Of course you need one jack for each lane.

In this case, the controllers need to be powered from a separate source. If you want your controllers to be powered from the same jack, it's easy: solder the black wire of the cartridge to the short-circuit between pins number 2 and 3 of the male jack and the red wire to the pin number 1of the male jack.

Note that there are diodes inside Hornby's PB. Hence, a 12V input gives a 10.8 V output on the rails.

You're almost done! Now that you have power to the rails, the only thing that's left now id to position the magnets under the track.

Lap and pit-lane detection To mark the finishing lane and the pit-lane on the track, it's necessary to use a few magnets. The magnets have to be glued under the track, on the left side of each lanes, facing the engine, with the south pole up.

Inverting the magnet polarity may cause missed laps, as the Hall sensor described earlier is sensitive to polarity.

Pit lane can be almost freely placed on your track in one of three possible configurations: the 'Crono' Race Management Software must be setup accordingly •

When in pit-lane, the car adjusts its maximum speed to 'pit lane speed' as set by the appropriate RMS knob.

As of car firmware release 2.01, the car coasts to the selected pit lane speed . This means that the speed reduction is not immediate as the car does not apply any direct braking, hence the effect may not be noticeable for short pit lanes. Later firmware versions instead brake shortly as soon as the pit lane is detected, so that the car sets its speed to 'pit lane' speed immediately.

As you know by now, magnets are used to detect the finish line and the pit lane area. What happens if a car stopped right above a magnet? As this may cause uncertainties in the lap and pit lane detection, starting from firmware 2.07, should the car chip detect that the model has come to a halt right above a magnet, it would automatically move forward to clear the 'magnet area' (note: only if the corresponding controller is on). Try putting a car a few cm before the FL magnet, then slowly move the car forward with your fingertip: at a certain point it will, by itself, jump a few cm forward: this happens when a FL is detected for a time longer than a defined threshold. You can use this feature to discover where the FL magnet is. Knowing where the magnets is may be important when reprogramming a car ID under certain conditions. Please refer to the 'ID Programming' section.

Base System Description

Car chip DC or AC+DC? The car is moved forward by the power it gets from the track. Such current and voltage can either be 'continuous', such as the one coming from a standard battery, or 'alternate', like the power mains. oXigen systems are preferably powered by DC power, and so are, in practice, Carrera and Ninco systems.

Scalextric SSD is unique in using AC power.

All oXigen chips are compatible with both: 1 - if the power on the rails is DC (analog track), or comes from Carrera or Ninco digital power bases, chips can be either in DC or AC+DC modes. In this latter case, the car will be able to run in both directions, but it will be slightly slower than if it was powered from the DC pad (0.5V loss approximately) 2 – if the rails are powered from an Hornby power base or a derivative, the AC setup must be used.

Unless you plan to use the chips on Scalextric SSD, leave them in DC mode, such as they are sold. Keep in mind that, anyway, the AC power mode is compatible with DC mode, but at the expense of some small power loss. To recap: for maximum power, and if system is DC, use DC mode (box stock). For universal compatibility, use AC pads:

The ''C' type chip The type 'C' chip is the most compact, powerful, compatible chip of its kind.

It's a truly universal device: natively compatible with oXigen, Scalextric SSD, and Carrera digital. 'Natively' means that the chip performs like any SSD or Carrera 132 system once the proper software is loaded.

Its shape is such that it fits on a Scalextric digital latch, in which case its double LEDs match the proper position for all of the above said systems, but, due to the dual LED on board, can also be used when rotated 90° in a oXigen or SSD system. Soldering pads are provided for a wired, additional LED. Like its predecessors, it can either be run in AC mode for Scalextric SSD, or DC only for oXigen or Carrera.

Switching between the two is done by changing a small screw's position on the PCB: no soldering is required.

Firmware can easily be updated from any mobile phones.

Type 'C' comes witha a red LED mounted on the top face which blinks according to the following table: Blinking type

The 'B2' type chip (preliminary information) The B2 type chip is a hybrid between B1, whose shape is retained, and C. It's designed for oXigen only, and uses the same connectors and pads that can be found on type B1 chip. Firmware updates are performed with the same procedure used for type C.

The 'B' and 'B1' type chip

To set the B'type chip in DC. or AC+DC mode, two separate sets of pads are provided, to connect the wires coming from the pickup: the pads for the DC systems are on top of the chip, whereas the ones to be used for the AC systems are located on the bottom side.

This chip also provides extra pads to use an external lane changer LED on wires. There is no need to remove the standard LED, which is mounted directly on the board.

Type 2 chip is sold with power wires connected to DC Pads. This is optimal for running on oXigen digital, and on analog tracks: the power is routed through one diode only, which keeps the voltage loss to a minimum. Such setup will work on Carrera D132 as well, but chipped car may only run in one direction.

If you plan to race the car on a Scalextric SSD sytem as well, or if you want to make it run both ways (for example to match the running direction on a Carrera D132 system), then the power wires from the pickup must be soldered to the AC pads. See image “SSD circuit� (C.) below. If necessary, an external, wired LED can be connected to the board, soldering the LED wires to the provided LED pads as shown (D.).

C.SSD ready circuit, bottom side

D.Circuit with wired LED, bottom side

Once the chipped is properly placed inside the chassis, make sure the LED can be seen through the chassis hole:

If you are running on Carrera D132 instead of oXigen or SSD, use the wired LED and place it so that it aligns with the Carrera receiver that can be found on the track, right before the lane changing mechanism.On the left side of the chip, attached to three wires colored in yellow, black and red, a unipolar Hall sensor works as lap and finish line detector. This sensor is responsible of sensing the magnetic field created by magnets that, when placed under the track, delimitate the finish line and pit lane. Said Hall sensor must be fixed to the chassis of the car so that front face of the sensor, the bevelled one, is facing down. This is very important: laying the sensor with the bevelled side up won't work (unless the magnets are also wrongly placed!). The sensor must be laid flat on the chassis as described in the picture.

The FERRITE MAN The name 'ferrite man' refers to the device made by one capacitor and one ferrite choke, which comes preassembled on the in-car chip wires, and that must be mounted on the motor terminals. Its purpose is to suppress electrical noise coming from the motor, that may interfere with the proper working of the in-car chip

The ferrite man is REQUIRED. It must be soldered on the motor copper tabs as described by these pictures

Short circuits of any of the 'ferrite man' limbs, either between themselves, or across any metallic parts (motor edges), will damage the in-car chip. Make sure the 'limbs' stay clear of each other and of any metallic parts

Car chip – type A (obsolete)

The O2 'type A' chip is now obsolete, having been replaced by type B. Car chip A can only run on DC, or on tracks powered by Ninco. It doesn't have any extra pads for AC systems nor any extra pads for wired LED. Type A chip is designed to fit the car as shown in the picture.The sensor has to be angled upwards at an angle of 45° at least (angle α in picture). This is very important: laying the sensor with the bevelled side up won't work, and placing it flat on the chassis will cause detection of false laps. So: face down, angle up! Apart from the differences above, everything said for the type B chip applies.

Should you experience flase lap detection when changing lane, the reason is the high sensitivity of the Hall sensor in type A chips, which can detect the magnetic field of the activation coil during lane changing. Bend the sensor more, or add some spacers underneath until the problem goes away.

If you are using a 'Type 2' chip, forget the above and leave the sensor flat on the chassis (rouned edge facing downwards) Besides, the Hall sensor is a current sensor, so keep it away from the power wires leading from track to chip, and from chip to motor.

oXigen in-car chip 'modes' oXigen chipped cars can run on most commercially available digital systems: Scalextric SSD, Carrera D132, as well as of course oXigen native. In most cases, the communication between the car and the lane changers and/or lap counter is done through an infrared-emitting LED. Unfortunately, while oXigen and SSD share the basics of such infrared protocol, SSD and Carrera systems are completely different. For this reason, each car must be programmed so that its working 'mode' is appropriate for the intended use.

Currently there are 5 such modes, one being still unused. oXigen in-car chip working modes Mode name

Controller and car link – setup and programming SCP-3 The SCP-3 is natively compatible with oXigen. There is no need to add any cartridges to it, to use it in an oXigen system.It's also compatible with all SCP cartridges.

The SCP-3 can be powered with a LiPo battery placed inside the controller handle, in place of the cartridge. Such battery is charged with a standard micro USB type charger through the provided micro USB interface.

In its basic form it sends and receives data on the 2.4GHz frequency channels with enough power to cover normal home conditions and distances. However, it can also be upgraded with a high power module if really long distances must be reached. Further, when the high power module is fitted, the original transmitter becomes a Bluetooth device, which can be paired to smart phones to save racing data and other information. Firmware is updated through a dedicated app, from any mobile phone.

It operates like any other SCP controller, but comes with two LED displays for better ease of use, so that for example IDs are displayed as two digit numbers. For the rest, refer to the following “SCP2 and SCP1� paragraph.

SCP2 and SCP-1 Both type of controllers need the oXigen cartridge to operate in an oXigen environment.

First thing - check the jumper: make sure to set the jumper on the oXigen cartridge properly: if you have an SCP 1.0, leave the jumper in place shown in the picture, else, for SCP 1.1 and greater, remove it.

Select operating mode: Starting from firmware 2.13 (controller) and 2.09 (car), it is possible to select the operating mode (oXigen native, SSD, D132) directly from the controller with no need for dongle or bootloder procedure. Please double check the

firmware compatibility cross table at the end of this document to make sure you are programming the car with appropriate versions for the controller and car boards.

Base System Description Check if the car is paired already - if not, assign an ID and pair it:

You may check now if the chipped car is already linked to the controller: power the track (make sure power is on the rail), verify that controller is on, and put the chipped car on the track: if the cartridge red LED blinks very fast, it means the car is already linked to the controller and you can start playing.

1. To check the current ID of the controller, press the round button: the display on the cartridge shows the current track, and the current channel of the car (cycling in this order :'t' ('track'), number of track, c ('channel'), number of channel, system type ('d' for Carrera D132, 'h' for Hornby SSD, 'o' for oXigen, and yes it's 'doh'). The dot on the low right side of the number, if lit, is the decimal light that is: ' 9 ' means nine; Â ' 9. ' (nine with dot) means nineteeen. Number twenty is displayed as '||.'

2. To program a new channel, do as follows: 1. remove car from track 2. channel is programmed through the controller knobs. Proceed as follows: 1. The yellow (MIN) knob selects the track number: 0 -10= track 1, 10-20 track 2 and so on.

Leave it at zero. For the time being, it has no effect, anyway.

2. The green (Antispin) knob selects the tens: set it between 0-10 for cars 1-9, 10-20 for cars 11 to 19, 20 and above for car 20 3. The blue (Curve) knob sets the units: 0 to 9 (minimum is 1) 4. The red (Brake) selects the system: turn fully counterclocwise (left) for Carrera D132, set to '0' (middle position) for Hornby SSD, set to 'two o' clock' for oXigen hybrid, turn fully clockwise (right) for pure oXigen. Note that this is necessary only if you want to change system to a different type. If you just need to change ID, this knob is not used.

3. now check the values that you are about to program by pressing the 'down arrow' together with the circular button: the display will show the settings for the track n. (currently, this can only be '1'), and the car ID. You can adjust them on the fly and as long as you keep pressing the down arrow and the round button, any changes are shown in real time. For example 't1 c8' means track 1, car ID n.8 and looks like this (leds turn on in sequence): 20 10

Important note: in this case, if you've reprogrammed the system as well as the ID (i.e. you've pressed both arrow and the circular buttons, and pulled the trigger), and your controller was in 'linear' mode (rear switch of the SCP on 'LIN'), then at this point your controller is in 'ghost' mode and your car may take off by otself. Exit the 'ghost' mode by pressing the trigger once, fully, before putting your car back on track.

5. once you are happy with the values, keeping the 'down arrow' and the round button pressed, pull the trigger fully and place the car to link with, on the (powered) track. The display LED will 'circle' for a while (usually it's a very short time) and then will flash, confirming the correct programming. If the LED keeps circling, remove the car from the track, and repeat this step.

When programming is finished, the display LED will show a number (the channel just programmed). Reset car (remove from track and put back on track). The link between car and controller is shown by the fast blinking of the LED on the cartridge.

6. all of the above applies if you want to change to a different system, too, with the exception that you must press all the buttons (arrow up, arrow down and circular) and then pull the trigger.

Relinking controller and car If you need to link the car to a controller other than the one that the car is currently linked to, you must in general make sure that the current 'owning' controller is switched off. This is a safety measure to prevent accidental reprogramming of someone else's car. However, starting from car firmware version 2.07Â it is possible to reprogram the ID of a car to a different ID even if the car chip to be programmed is linked to a controller which is currently live. Now, if you need to perform such operation, that can be very handy sometimes (e.g. using one of your friends' cars while your friend is racing without asking him to switch his controller off), do as follows: if you know where a magnet is, put the controller, the one that you want to pair with the car, in programming mode (select ID and press the trigger), then put the car on track right above the magnet, so that the chips wakes up with a magnet under the Hall sensor: under these conditions it will ignore any transmission from the previous controller and behave like a 'virgin' chip, accepting to be paired to any controller requesting to do so. Before you ask - with the new software the car will not stop inadvertently on a magnet - it will move forward automaticall to clear the area. This is also an easy way to find out where the magnets are.

Note that if the controller is switched off, and the car is taken off track, inside the pit lane, the pit lane status is lost, hence the 'end of pit lane' magnet will be detected not as a pit lane magnet, but as a finish line magnet, hence, one lap will be added to the lap counting. To avoid this, if both car and controller are switched off during pit lane, reposition the car after the pit lane exit magnet.

It is better to keep controllers at a distance of at least 30cm from each other.

Battery level: if a 'b' appears in the cartridge display, it's time to change battery.

Reset: the red dot in the cartridge display turns on and stays on for 1 sec. when the car chip resets, e.g. when the car is placed on rails after a deslot (controller/car firmware 2.10/2.07 onwards)

Dropped link: the bottom red line in the cartridge display turns on and stays on for 1 sec. when the car chip does not receive properly a communication frame. What this means in practical terms: if at a certain point the car does not receive timely throttle information from the controller, it has to slow down to avoid running away with no control and crashing. When this happens, it tries to cope with this situation as follows: if the loss happens during braking, then the car keeps braking as before. If, on the other hand, the link fails with open throttle, a gentle braking is applied for the first lost frame, only to switch to full brake if communication does not restart (controller/car firmware 2.10/2.07 onwards)

If you experience stuttering, look at the display: a red dot means you have an electrical problem (reset due to power loss), a red line shows a bad radio link, which may be caused by interference from the motor: make sure the ferrite and capacitor are properly soldered and try to route power wires away from the antenna.

Make sure you are using controller and car software that are mutually compatible.

Ghost cars: any car can be used as a ghost car by using the 'ghost' function of the SCP1. Alternatively, the RMS can take control of any car linked to a controller, imposing a minimum speed on a specific car. More than one car can be linked to one controller, hence you can use as many cars as you wish, but they'll all behave as one (e.g. same speed).

The major difference from the SCP-controlled ghost cars, and the cars that are driven from the RMS software, is that with the SCP 'ghost' feature, cars change lane randomly, whereas if it's the RMS driving, this is not the case.

Herding: If the 'selective lane change' is available on your track, all cars can be forced to pit lane by the RMS.

Lane change Refer to the Lane Change Driver manual file for detailed instructions.

Using Arc Air/Pro Controller as oXigen controller Any Scalextric Arc Air/Pro controller (ref. C8438) can be turned into an oXigen controller uploading the appropriate firmware into the unit. The operation can be done with a mobile phone equipped with either iOS or Android, and Nordic Semiconductor's 'nRF Toolbox' app.:

Firmware Update Prepare for the update: 1) Download the "nRF Toolbox for BLE" app by Nordic Semiconductor ASA from the Google Play store, and install it.

2) Download the O2ArcHCYYMMDD.zip file (YYMMDD=date of issue) and save it to a known location on your mobile device. Such file is included in the standard 'latest release' zip file available from the Slot.it site, oXigen downloads section. It will be probably placed in your 'Download' folder on your phone or SD card.

Set Controller to DFU mode: 1) With the controller OFF, press and HOLD the Brake (X) button and switch the ARC controller on.

The controller should vibrate.

2) When the vibration stops, RELEASE the Brake button

4) When the vribration stops completely, RELEASE the trigger and button. The controller should now be in Device Firmware Upload (DFU) mode, and remain in that mode until programmed or reset by turning it off and back on.

Upload the firmware 1) Start the nRF toolbox app and select DFU 2) Tap on SELECT DEVICE and choose "DfuArcHC" which should appear in the list of available devices, below your list of paired/bonded devices. If it is not present, repeat the steps above to set the controller to DFU mode.

3) Tap on SELECT FILE, then ensure that "Distribution packet (zip)" is selected, then tap OK. 4) Using the file browser, locate and select the O2onArcHCYYMMDD.zip file. The app will return to the DFU screen when the file has been selected.

5) Tap on UPLOAD The controller resets automatically after being upgraded, but may need to be turned off and then back on to control the slot car.

Controller's eeprom is not changed, so no pairing should be needed if the controller was already paired.

Pairing to Car 1) Make sure any previously paired controller is turned off.

2) Put the car on the powered track. If it's an automatic car, make sure it's Hall sensor is positioned over a magnet.

3) Press and HOLD (in this order) the Lane Change (Y) and Brake (X) buttons.

4) When the LED turns ON for two seconds and then turns off, RELEASE the buttons.

5) Press the Brake button as many times as the ID you want to give the car. The LED lights each time the button is pressed.

6) Press and HOLD (in this order) the Lane Change (Y) and Brake (X) buttons and pull the trigger.

7) When the LED intensity increases then goes off and the controller vibrates, pairing was successfull and you can RELEASE the buttons and trigger.

Running with Hornby SSD Digital We've kindly been given, by Hornby Hobbies, the right to use Hornby's LED SSD protocol in conjunction with oXigen wireless system. This means that an O2 car can run on an SSD system, be recognised by the SSD Power base as one SSD car, whose ID is 1 to 6 depending on its oXigen ID, and of course change lane.

In other words: if, using the bootloader application or the controller (2.13 and higher, car 2.09 and higher), the car is set in 'SSD mode' and if it is programmed with ID 1 to 6, Hornby 's SSD Power Base (PB) will count its laps as if it was a SSD car. SSD lane change track pieces will work as expected, too.

Note that the oXigen chipped cars do not read the SSD protocol from rails, hence, they do not respond to start/stop race commands from the SSD Power Base. Besides, please refer to the car chip section regarding the DC vs. AC power, as the SSD power is AC. It is also possible to run more than 6 cars on the same SSD track at the same time: in this case cars 7-20 must be O2 ones: to achieve this, place the Finish Line magnets according to the standard oXigen placement, right before the SSD Power Base finish line. An oXigen car, when programmed in SSD mode with ID 7-20, uses a slightly modified Selective Lane Change protocol to change lane, such protocol being backwards compatible with Hornby's LCs, and, in order to avoid any confusion with the PB, upon detecting the Finish Line magnet, shuts down its LED transmission for about 200mS. This also means that no lane changing can take place, for cars 7-20, for 200mS after the finish line.

Required, must be placed right PC dongle only before PB FL. Upon detection, car shuts down its LED for 200mS

PB=SSD Power Base FL=Finish Line Most likely, a standard Hornby PB will not provide enough power to run so many cars. There are, however, aftermarket parts that may provide higher power output.

Note also that for a oxigen chip & car laps to be counted by the APB, you need a dummy controller in the APB port corresponding to the car ID.

Base System Description

Running with Carrera Digital D132 It is possible to run an oXigen chipped car on Carrera Digital D132. This is done independently of Carrera protocols and technology. Actually, it is the D132 PB that does the job for us. A fully working Carrera D132 system (PB + LCs + controller) is required.

In D132 systems the PB transmits the status of the 'change lane' buttons on the hand controllers, to all the lane change units. Car chips, instead, know nothing about the lane change button: they go around the track transmitting their fixed ID continuosly through the IR LED. The LC thus knows from the PB if a certain car must change lane, and once such car is recognised, the LC mechanism is activated.

An oXigen car in D132 mode sends its ID only when the LC button is pressed: in all other cases (except for lap counting), it goes around undetected. If, at the same time, the PB senses from its own controller that such car wants to change lane, and the oXigen LC button is pressed, any LC can pick up the infrared ID from the car, which can thus change lane at will.

To count laps, though, you must place a oXigen FL magnet right before the Carrera D132 FL sensor to trigger a 200mS transmission of the car's ID, which will be picked up by the FL sensor. Thus, a LC must not be placed right after the FL, or the O2 cars will change lane.

To summarise, how to do? First, with the Bootloader software (0.12 and higher), or controller (2.13 and higher, car 2.09 and higher) put your O2 car in D132 mode. Then, program it with ID ranging between 1 and 6. Last, plug your Carrera controller in the PB slot corresponding to said ID, lock the LC button on the 'ON' position (for example, with a rubber band), make sure magnets are placed under the FL, and you're ready.

Note that the oXigen chipped cars do not read the Carrera digital protocol from rails, hence, they do not respond to start/stop race commands from the Power Base.

It is also possible to run more than 6 cars on the same Carrera track at the same time. Again, you need the magnets under the FL. In this case cars 7-20 must be O2 ones and Carrera ID 4 is reserved for O2 extension.

You need a Carrera controller hooked to controller plug n.4 with its LC button locked on. Then, simply, put your cars in D132 mode, set them to ID 7 to 20, and run them. In this case an oXigen dongle is requiredfor lap counting.

Lane Changing O2 car, D132 mode, Needs Carrera controller (or ID 1 to 6 shorted jack) with LC button pressed in the same PB slot as the car's ID

Magnet

Lap counting

Required, must be placed right D132 PB and before D132 FL. It triggers an (optional) PC dongle oXigen FL signal to the O2 controller as well as a D132 lap.

O2 car, D132 mode, Needs Carrera controller (or Required, must be placed right ID 7 to 20 shorted jack) with LC before D132 FL. It triggers an button pressed in PB slot n.4 oXigen FL signal to the O2 controller.

PB=D132 Power Base FL=Finish Line

PC dongle only

Note that the IR LED must be displced to match the position of the receiving LED on Carrera track, so a LED on wires is advisable, together with a O201b chip.

Most likely, a standard Carrera PB will not provide enough power to run more than 6 cars. There may be, however, aftermarket parts providing higher power output.

Cartridge Radio Interface (CRI) The O2 Cartridge Radio Interface (CRI), when used together with an oXigen SCP cartridge, creates a radio wireless communication link between the hand controller (SCP only) and any available SCP cartridge analog or digital, turning in fact a SCP controller into a wireless system for any slot car racing system in the world – analog (common ground or common positive) or digital (Hornby, Carrera, Ninco, SCX).

In detail, the CRI is a pocket size receiver accepting any SCP cartridge: think of it as the top of the SCP controller, but with no knobs or trigger. It connects by 2.4GHz radio link to the oXigen cartridge which is plugged into the SCP controller, and transmits in real time the power, brake and any other commands (lane change, lights, etc.) coming from the controller to the cartridge, thus creating a wireless, remote control SCP system for all the SCP-1 supported systems: .

How does it all work? As far as the SCP + O2 cartridge know, the CRI is just an O2 car chip. At the CRI end instead, the data received from the SCP are passed on to the final cartridge. It's very simple.

In practice the CRI has to be paired to the SCP following the same procedure described above for “controller and car link – setup and programming”. Note that the position of the brake knob of the SCP (which is used to select between oXigen, Hornby SSD or Carrera digital) is irrelevant.

Controller and CRI link – setup and programming You need one SCP controller handle, one oXigen cartridge, the correct analog or digital cartridge for your system and one CRI. Plug the oXigen cartridge into the SCP. Plug the analog or digital cartridge into the CRI, as if the CRI was a controller. Teh system will look like the one in the picture: a complete SCP with oXigen cartridge, and one analog or digital cartridge assembled with the Common Radio Interface box.

Prepare and check your controller as if you were about to link to a car. Everything applies, except the position of the brake knob, which is irrelevant. Once ready, plug your cartridge/CRI combination into your track power supply, and link it to the controller following the usual procedure. If you already know how to link one car, you can skip the rest of this chapter. Else, read below.

First of all: make sure to set the jumper on the oXigen cartridge properly: if you have an SCP 1.0, leave the jumper in place shown in the picture, else, for SCP 1.1 and greater, remove it.

You can check now if the CRI is already linked to the controller: power on the track and controller: if both the cartridge and the CRI red LEDs blink fast, the CRI is already linked to the controller and you can start racing.

1. To check the current ID of the controller, press the round button: the display on the cartridge shows the current track, and the current channel of the CRI (cycling in this order :'t' ('track'), number of track, c ('channel'), number of channel, system type ('d' for Carrera D132, 'h' for Hornby SSD, 'o' for oXigen, and yes it's 'doh', but this information can be ignored with the CRI). The dot on the low right side of the number, if lit, is the decimal light - that is: ' 9 ' means nine; Â ' 9. ' (nine with dot) means nineteeen. Number twenty is displayed as '||.'

2. To program a new channel, do as follows: 1. switch off the CRI 2. channel is programmed through the controller knobs. Proceed as follows: 1. The yellow (MIN) knob selects the track number: 0 -10= track 1, 10-20 track 2 and so on.

Leave it at zero.

2. The green (Antispin) knob selects the tens: set it between 0-10 for CRI 1-9, 10-20 for CRI 11 to 19, 20 and above for CRI 20 3. The blue (Curve) knob sets the units: 0 to 9 (minimum is 1) 4. The red (Brake) position is irrelevant with the CRI. 3. now check the values that you are about to program by pressing the 'down arrow' together with the circular button: the display will show the settings for the track n. (currently, this can only be '1'), and the CRI ID. You can adjust them on the fly and as long as you keep pressing the down arrow and the round button, any changes are shown in real time. For example 't1 c8' means track 1, CRI ID n.8 and looks like this (leds turn on in sequence): 20 4 10

4. once you are happy with the values, keeping the 'down arrow' and the round button pressed, pull the trigger fully and turn on the CRI. The display LED will 'circle' for a while (usually it's a very short time) and then will flash, confirming the correct programming. If the LED keeps circling, power off the CRI, and repeat this step. When programming is finished, the display LED will show a number (the channel just programmed). The link between CRI and controller is shown by the fast blinking of the LED on the cartridge.

5. Make sure that there are no other CRI or cars with the same ID.

Controller, oXigen cartridge and ARC AIR / PRO – setup and programming The 2.4 GHz link between Scalextric ARC AIR/PRO Power Base and Controllers was developed by Galileo Engineering, also known as Slot.it, for, and in strict cooperation with, Hornby Hobbies plc. All that was learnt from developing Slot.it's own digital wireless system during the course of many years has been transferred into Scalextric ARC system, creating a fantastic wireless system with great reliability, smoothness of operation, and operating range, for the beginner and the experienced racer alike.

As it could be expected, any SCP controller with oXigen cartridge is the perfect controller racing upgrade to Scalextric ARC AIR/PRO systems. All you have to do is to load the appropriate firmware, which can be grabbed from Slot.it's oXigen download pages, and program the cartridge using the usual oXigen bootloader application. Once this is done, your SCP will be ready to operate as an ARC controller. All the SCP controls remain operational, with the exception of variable braking, which will only become available later on.

Operating instructions 1. Grab ARC AIR/PRO compatible firmware from Slot.it web site, oXigen download section. The firmware to be used belongs to the ‘5.x’ family, that is, for example, boot_ctrl_5_00_ARC.txt 2. Transfer firmware into SCP's memory using oXigen bootloader application 3. Pair the SCP controller to Scalextric ARC Power Base as if it was a ARC AIR/PRO controller: press the channel button on the Power Base, then press the ROUND and ARROW DOWN buttons together and pull the trigger.

4.

When the controller is paired, the link LED on the cartridge blinks like it does oXigen mode.

5. press the BRAKE button to show the ARC track ID (1-4) and current channel ID (1-2 for AIR, 1-6 for PRO) The SCP3 (wireless only, battery powered SCP) automatically detects whether it's being used in an oXigen or ARC environment and adapts accordingly, without any reprogramming.

Galileo Engineering – Slot.it signed driver installation guide This guide describes how to install the self-signed drivers released by Galileo Engineering srl – Slot.it To start with, the latest Windows OS (Windows 7 onwards) requires digitally signed drivers. These files include an electronic fingerprint indicating the details of the issuing company and a few more parameters.

Signing a driver is an important security measure, because a malicious infection may not modify a signed driver without compromising its signature. Thus, drivers are signed using code signing certificates. Unsigned drivers can still be installed under Windows OS anyway, disabling signature verification, but it's not a recommended practice. The procedure is well explained on many websites but is not user friendly and, frankly, is not a very professional practice.

Galileo Engineering currently provides digitally signed drivers for two USB devices: oXigen Dongle and Live Timing Box (LTB). Compressed folders with all necessary files can be downloaded directly from the download section og the Slot.it web site (http://www.slot.it). The following examples refer to oXigen dongle driver installation but apply to the Live Timing device as well.

Installation is a two steps process: 1 – Signed certificate installation 2 – Driver Installation

1 – Signed certificate installation This should be required once only, that is, the first time a Slot.it USB device is installed on the PC. The procedure intalls a Galileo Engineering digital certificate which is used by Windows to make sure that the Slot.it signed drivers can be trusted. A trusted driver will not be removed every time Windows gets updated, which is what happens to unsigned drivers instead.

Download the compressed driver files folder from the Slot.it website and uncompress the folder, which includes three files: 1 : a text file consisting of the driver information (.inf) 2 : a catalog file used as digital signature for the driver file (.cat) 3 : company signed certificate (.cer) The first step is installing the Galileo Engineering certificate: doubleclick on certificate file (GalileoEngineeringsrl.cer in the example) • click on Install Certificate • select Local Machine → Next • select Place all certificates in the following store and browse Trusted Root Certification Authorities → Next • click on Finish • confirm with OK From now on, all drivers that are signed with the certificate will be trusted.

oXigen es el nombre comercial del sistema digital de carreras de slot cars estudiado y desarrollado por Slot.it. Básicamente, se trata de un sistema inalámbrico que permite ejecutar carreras digitales de slot con hasta 20 coches en la misma pista. Los coches con el chip pueden correr en sistemas analógico, oXigen, Hornby SSD o Carrera D132.

El sistema oXigen (de ahora en adelante “O2”) se basa en los siguientes dispositivos: 1. cartucho digital oXigen compatible con mando SCP Slot.it ; 2. chip digital oXigen para el coche; 3. chip digital oXigen para el cambio de carril, adecuado para pedazos de pista de cambio carril (simple, X , entrada pit-lane) cosntruido por Ninco y Carrera; 4. dongle oXigen para sistema digital. Éste manual está actualizado para versión de firmware: coche 2.09, mando 2.14, dongle 2.05.

Pista Para correr, O2 necesita una alimentación de DC constante en los carriles, polo (+) en el lado derecho del coche mirando hacia delante.

A partir de una pista de slot analógica estándar, todo lo que se necesita es un adaptador para llevar la energía al carril. En general, un simple cable con dos bananas, y un fusible (altamente recomandado – conmutación rápida, 6A) harán el trabajo. Ésto es necesario para todos los carriles donde se desea correr con coches O2. Ésto es todo lo que hay que hacer: quite el cable, y regresa a la carrera tradicional analógica. Puede hasta correr digital en algunos carriles, y dejar los demás analógicos.

Los coches O2 pueden correr en pistas accionadas por Hornby, Ninco, o bases digitales Carrera. En el caso de la base Hornby, puede ser que se necesite instalar un “puente” adicional adentro del coche, dependiendo de cual chip O2 se está utilizando.

NOTA:

la polaridad de la alimentación en pista Carrera puede ser invertida en comparación con la norma general aceptada, que es (+) en la derecha, (-) en la izquierda. Teniendo en cuenta ésto, durante la instalación del chip en el coche, podría ser necesario invertir la posición de los dos cables en el pick-up de los coches O2 o soldar los cables en contactos con puente (para corriente alterna - CA) del chip tipo 2. Por favor lea la sección correspondiente.

Una pista Scalextric Sport puede también ser reversiblemente convertida en una pista compatible con oXigen por medio de un jack macho de 3,5 mm hecho por encargo, como descrito a continuación.

Dentro de cada toma jack varón, de 3.5mm de diámetro, crear un cortocircuito entre las clavijas número 2 y 3. Una vez que éste jack está conectado en la power base de Hornby, toda la energía se le dará a los carriles haciendolos por lo tanto adaptos al sistema O2. Una buena práctica sería colocar un fusible allí también...

Nos hemos dado cuenta que es fácil olvidar que los carriles están conectados/vivos, lo que significa que si usted lleva algo sobre la pista, destornilladores etc. puede fácilmente producir un cortocircuito. Por supuesto se necesita un jack para cada carril.

En éste caso, los mandos necesitan ser alimentados desde una fuente separada. Si desea que sus mandos sean alimentados de la misma toma, es fácil: solde el cable negro del cartucho al cortocircuito entre los pines número 2 y 3 del conector macho y el cable rojo con el pin número 1 del jack macho .

Tenga en cuenta que existen diodos dentro de la PB de Hornby. Por lo tanto, una entrada de 12V da una salida de 10.8 V en los carriles.

En la parte izquierda del chip, el detector de la vuelta y de la línea de meta, un sensor unipolar 'Hall', está pegado a los tres cables de color amarillo, negro y rojo...Éste sensor se encarga de detectar el campo magnético de la línea de meta y de los boxes (que se ha colocado debajo de la pista) y debe estar fijado al chasis del coche de manera que la cara frontal del sensor, la biselar, mire hacia abajo . El sensor debe estar hacia arriba y debe crear un ángulo mínimo de 45 °, ángulo α en la imagen siguiente. Ésto es muy importante: dejar el sensor con el lado biselar hacia arriba no permite que funcione, y colocándolo plano sobre el chasis provocará la detección de falsas vueltas. Por lo tanto: boca abajo, ángulo arriba!

En caso de experimentar falsa detección de vuelta al cambiar de carril, la razón es la sensibilidad del sensor Hall, que puede detectar el campo magnético de la bobina durante el cambio de carril. Hay que doblar el sensor más, o añadir algunos separadores por debajo hasta que el problema desaparezca.

Si Usted está usando un chip 'Tipo 2',olvide lo de arriba y deje el sensor plano sobre el chasis (borde circular hacia abajo) Además, el sensor Hall es un sensor de corriente, por lo tanto hay que mantenerlo alejado de los cables de alimentación que van de camino desde la pista al chip, y desde el chip al motor.

La antena del chip,el trozo de cable situado en la parte inferior derecha, debe sera mantenida vertical, por cuanto posible. No se recomineda poner la antena hacia abajo en el chip o cerca del motor. Funcionará, pero no es una buena práctica.

Car chip – tipo 2 El chip para el coche de tipo 2 difiere del tipo 1 en tamaño, y en su capacidad de funcionar en cualquiera AC(por ejemplo: SSD power base), o DC (por ejemplo: pistas analógicas), en éste último caso, sin la pérdida de una caìda de diodo (0,5 V) que es tipico de los chips del modo dual (AC y DC). Para ésto, hemos dividido las almohadillas que deben ser utilizadas para conectar los cables que llegan desde la guìa: las almohadillas para los sistemas de DC están en la parte superior del chip, mientras que los que se utilizan para los sistemas AC se encuentran en la parte inferior lado.

Resumiendo: 1 – si la alimentación en los carriles es DC, o viene de una power base digital Carrera o Ninco, Usted puede utilizar cualquiera de los pads de DC (arriba), donde el + está en el lado derecho, o al final de las almohadillas AC, cuya polaridad puede ser cualquiera de ellos. En éste último caso, el coche será capaz de funcionar en ambas direcciones, pero será un poco más lento que si fuera alimentado desde los contactos para corriente directsa (CC).

2 – si los carriles está alimentados por una power base Hornbyif o un derivado, se deben usar las almohadillas AC. Éste chip también ofrece extra pads para usar un LED de cambio carril externo sobre los cables. No hay necesidad de remover el LED standard, que está montado directamente en la placa. rev 1.44 es, 26/07/13

Aparte de las diferencias mencionadas anteriormente, todo lo que se ha dicho para el chip tipo 1,es aplicable.

El chip de tipo 2 se vende con los cables de alimentación conectados al DC Pads. Ésto es óptimo para correr en oXigen digital, y en pistas analógicas: la potencia se enruta a través de un solo diodo, lo que manitene la pérdida de voltage a un mínimo. Ésta configuración funcionará también en Carrera D132, pero el coche funcionará solamente en una dirección.

Si Usted planea correr el coche en sistemas Scalextric SSD también, o si desea que corre en ambos sentidos (por ejemplo para que coincida con la dirección de marcia en un sistema Carrera D132), entonces los cables de alimentación desde la guía deben ser soldados a las almohadillas AC. Ver imagen “circuito SSD” (C.) a continuación. Si es necesario, una cable LED externo, puede ser conectado a la placa, soldando los cables del LED a las almohadillas LED provistas como se muestra (D.).

Para comprobar la ID actual del mando, pulse el botón redondo: la pantalla en el cartucho muestra la pista actual, y el canal actual del coche (circulando en éste orden :'t' ('track/pista'), número de pista, c ('channel/canal'), número de canal, tipo de sistema ('d' para Carrera D132, 'h' para Hornby SSD, 'o' para oXigen, y sí es 'doh'). El punto en el lado derecho bajo el número, si está encendido, es la luz decimal – es decir: ' 9 ' significa nueve; ' 9. ' (nueve con punto) significa diecinueve. N úmero veinte se muestra como '||.'

2. Para programar un nuevo canal, haga lo siguiente: 1. quite el coche de la pista 2. el canal se programa a través de los botones del mando. Proceda de la siguiente manera: 1. El botón amarillo (MIN) selecciona el número de la pista: 0 -10= pista 1, 10-20 pista 2 y así sucesivamente. Dejelo en cero.

2. El botón verde (Antispin) selecciona las decenas: regular entre 0-10 para los coches 1-9, 1020 para los coches de 11 a 19, 20 y arriva para el coche 20 3. El botón azul (Curve) establece las unidades: 0 a 9 (mínimo es 1) 4. El rojo (Brake/Freno) selecciona el sistema: se gira una vuelta completa en sentido antihorario (izquierda) para Carrera D132, poner a '0' (posición media) para Hornby SSD, se gira una vuelta completa en sentido horario(derecha) para oXigen. Tenga en cuenta que ésto es necesario sólo si se desea cambiar el sistema a un tipo diferente. Si Usted tiene sólo que cambiar ID, no se debe utilizar éste botón.

3. ahora chequee los valores que está a punto de programar pulsando la 'flecha hacia abajo' junto al botón circular: la pantalla mostrará la configuración para la pantalla n.(actualmente, ésta puede ser solo '1'), y el ID del coche. Usted puede ajustarlo durante la marcha, pues mientras se mantengan la flecha hacia abajo y el botón redondo pulsados, cada cambio se muestra en tiempo real. Ej.: 't1 c8' significa pista 1, ID del coche n.8 y parece a ésto (los leds se encienden en secuencia): 20 4 10

5. una vez que esté satisfecho con los valores, manteniendo pulsados la “flecha hacia abajo” y el botón redondo, apretar completamente el gatillo y colocar el coche de enlazar, en la pista (con alimentación). La pantalla LED “circulará” por un tiempo (en general muy poco tiempo) y luego parpadea, confirmando la correcta programación. Si el LED sigue dando vueltas, quite el coche de la pista y repita éste paso. Una vez finalizada la programación, la pantalla del LED mostrará un número (el canal acabado de programar). Restablecer el coche (quitarlo de la pista y ponerlo de nuevo en la pista). La conexión entre coche y mando se muestra por el rápido parpadeo del LED en el cartucho.

6. Todo lo anterior se aplica si se desea cambiar a un sistema diferente, también, a excepción del hecho que hay que pulsar todos los botones (flecha arriba, flecha abajo y circular) y luego apretar el gatillo.

Reconectar mando y coche Si necesita conectar el coche a un mando, diferente al que ya está conectado al coche, usted debe en general, asegúrarse que el mando actualmente “dueño” esté apagado. Ésta es una medida de seguridad para evitar reprogramación accidental del coche de otra persona. Sin embargo, a partir de los coches con firmware versión 2.07 es posible reprogramar el ID de un coche a un diferente ID, incluso si el chip del coche que debe ser programado ya està vinculado a un mando que actualmente está conectado. Ahora, si usted necesita cumplir con dicha operación,que puede ser muy útil a veces, (e.g. usando uno de los coches de su amigo mientras que esté corriendo, sin pedirle de apagar su mando), haga lo siguiente: si usted sabe adond eestá un imán, ponga el mando, el que desea emparejar con el coche, en el modo de programación (seleccione ID y pulse el gatillo), en seguida ponga el coche en la pista justo sobre el imán, de manera que los chips se despierten con un imán bajo el sensor Hall: en éstas condiciones ignorará cualquier transmisión desde el mando anterior y se comportará como un chip 'virgen', aceptando de ser emparejado a cualquier mando que lo solicite. Antes que lo pida – con el nuevo software el coche no se parará involuntariamente sobre el imán – seguirá moviendose automáticamente para limpiar la zona. Ésta es también una manera fácil para averiguar donde están los imanes.

Tenga en cuenta que si el mando está apagado, y se quita el coche de la pista, dentro de la pit lane, el “estado” pit lane se pierde, por lo tanto el imán “fin de la pit lane” será detectado no como un imán de la pit lane, si no como un imán de la linea de meta, por lo tanto, será añadida una vuelta al cuenta vuelta. Para evitar ésto, si ambos, coche y mando, están apagados durante la pit lane, vuelva a colocar el coche después del imán de la pit lane existente.

Es mejor mantener los mandos a una distancia de al menos 30cm entre ellos.

Otras funciones Luces: encender/ apagar las luces: el chip del coche es compatible con el kit de luces SP16b. Para prender/apagar las luces, suelte el gatillo y presione el botón circular 'brake'.

Nivel de la batería: si la pantalla del cartucho muestra una 'b' , es el momento de cambiar la batería.

Reset/ restablecer: el punto rojo en la pantalla del cartucho se enciende y permanece por 1 seg. cuando el chip del coche se restablece, e.g. cuando el coche se coloca e los carriles después que el coche salió de pista (mando/coche firmware 2.10/2.07 más adelante)

Dropped link / Enlace caído: la línea roja inferior en la pantalla del cartucho se enciende y permanece encendida por 1 seg. cuando el chip del coche no recibe correctamente una trama de la comunicación . Qué significa ésto en términos prácticos: si a un cierto punto el coche no recibe informaciones de aceleración puntuales desde el mando, se debe reducir la velocidad para evitar que se vaya sin control y se estralle.

Cuando ésto sucede, el sistema intenta resolver ésta situación de la siguiente manera: si la pérdida ocurre durante la frenada, entonces el coche sigue frenando como antes. Si, al contrario, el enlace falla con el acelerador abierto, se aplica una frenada suave por la primera trama perdida, sólo para cambiar a frenada máxima si la comunicación no reinicia (mando/coche firmware 2.10/2.07 más adelante)

Si Usted experimenta tartajeo, mire la pantalla: un punto rojo significa que tiene un problema eléctrico (reset debido a la pérdida de potencia), una línea roja muestra un enlace de radio malo, que puede ser causado por interferencia del motor: asegúrese que la ferrita y el condensador estén correctamente soldados y trate de orientar los cables lejos de la antena.

A segúrese de utilizar el software de mando y del coche compatibles entre ellos. rev 1.44 es, 26/07/13

Coches fantasmas: cualquier coche puede ser utilizado como coche fantasma mediante el uso de la función 'ghost' del SCP1. Alternativamente, el RMS puede tomar el control de cualquier coche vinculado a un mando, imponiendo una velocidad mínima en un coche específico. Más de un coche puede estar vinculado a un mando, por lo tanto se pueden usar todos los coches que desea, pero ellos se comportarán todos como si fueran uno (e.g. misma velocidad).

1. La diferencia principal entre los coches fantasmas controlados por SCP, y los coches manejados desde el software RMS, es que con la función “fantasma” del SCP, los coches cambiam de carril de forma aleatoria, mientras que si es el RMS que maneja, no cambian aleatoriamente.

Reunión: Si el 'cambio de carril selectivo' está disponible en la pista, todos los coches pueden ser obligados a reunirse en la pit lane por el RMS.

Detección vuelta y pit-lane Para marcar la línea de meta y el pit-lane en la pista, es necesario el uso de unos imanes. Los imanes deben ser pegados debajo de la pista, en el lado izquierdo de cada carril, con el frente hacia el motor, con el polo sur hacia arriba. Consulte la imagen 1. Sobre la posición de los imanes en la pista, la configuración sugerida es aquella reportada en la imagen 2. Los imanes F1, F2 y F3 trabajan como una línea de meta. P1 y P2 son el inicio y el punto final del area pit-lane. La distancia entre F3 y P1 debe ser entre 5 y 10 cm. De todos modos, el coche entra en el pit-lane si lee dos imanes dentro de 320ms.

Figure 1: Figure 2: placement of magnets

Cuando está en el pit-lane, el coche ajusta su velocidad máxima a la “velocidad pit-lane” como fijada por el botón apropriado de RMS. A partir de la version 2.01 del firmware, el coche va a la velocidad del pit lane seleccionado. Ésto significa que la reducción de la velocidad no es inmediata ya que el coche no aplica ningún freno directo, por lo tanto el efecto podría no ser evidente para pit-lanes cortos.Las ultimas versiones rev 1.44 es, 26/07/13

del firmware en vez frenan brevemente tran pronto como es detectado el pit-lane, de manera que el coche ajuste su velocidad a “velocidad pit-lane” inmediatamente.

Como ustedes saben al momento, los imanes se utilizan para detectar la línea de meta y el area pit-lane. ¿Que ocurre si un coche se detiene justo sobre un imán? Como ésto puede causar incertidumbre en la detección del la vuelta y del pit-lane, a partir del firmware 2.07, en caso que el chip del coche detecte que el modelo ha llegado a su parada justo sobre el imán, éste sería automaticamente movido hacía adelante para limpiar el “area imán” (nota: solo si el mando correspondiente está encendido). Trate de poner el coche unos centímetros antes el imán de la FL, luego mueva lentamente el coche havia adelante con el dedo: a un cierto punto él mismo saltará algunos centímetros hacia adelante. Ésto sucede cuando una FL se detecta por un tiempo más largo que un umbral definido. Usted puede utilizar ésta función para descubrir adonde está el imán de la FL. Saber adonde está el imán puede ser importante cuando se reprograma el ID de un coche bajo ciertas condiciones. Por favor, consulte la sección “Programación ID”.

Correr con Hornby SSD Digital Se nos ha dado generosamente, por parte de Hornby Hobbies, el derecho de utilizar el protocolo LED SSD de Hornby en conjuncióín con el sistema inalámbrico oXigen. Ésto significa que un coche O2 puede correr en un sistema SSD, ser reconocido por la power base SSD como un coche SSD, cuyo ID es de 1 a 6 dependiendo de su ID oXigen, y por supuesto cambiar de carril.

En otras palabras: si, usando la aplicación bootloader o el mando (2.13 y superior, coche 2.09 y superior), el coche se encuentra en 'SSD mode' y si está programado con ID de 1 a 6, la Power Base (PB) de Hornby contará sus vueltas como si fuera un coche SSD. También las partes de pista de cambio de carril SSD funcionarán como uno se espera.

Tenga en cuenta que los coches con chip oXigen no leen el protocolo SSD desde los carriles, por lo tanto, no responden a los comandos de carrera start/stop desde la Power Base SSD. Además, por favor consulte la sección car chip con respecto a alimentación DC vs. AC , ya que la alimentación del SSD es AC. También es posible ejecutar más de 6 coches en la misma pista SSD al mismo tiempo: en éste caso los coches de 7 a 20 deben ser los de O2: para lograr ésto, colocar los imanes de la Finish Line de acuerdo a la colocación estándard oXigen, justo antes la línea de meta de la Power Base SSD. Un coche oXigen, si está programado en modo SSD con ID 7-20, utiliza un protocolo de cambio de carril selectivo un poco modificado para cambiar carril, que es compatible con el LC de Hornby, y , para evitar cualquier confusión con la PB, al detectar el imán de la FL, apaga su transmisión de los LED durante aproximadamente 200mS. Ésto signfica también que ningún cambio de carril puede ocurrir, para los coches de 7 a 20, por 200mS después de la FL. Lane Changing / Cambio carril

Correr con Carrera Digital D132 Es posible hacer correr un coche con chip oXigen en Carrera Digital D132. Ésto se hace de forma independiente de los protocolos y la tecnología Carrera. En realidad, es la PB D132 que hace el trabajo por nosotros. Se requiere un sistema Carrera D132 en pleno funcionamiento (PB + LCs + mando).

En los sistemas D132 la PB transmite el estado de los botones 'change lane' en los mandos de mano, a todas las unidades de cambio carril. Los chips de los coches, en vez, no saben nada sobre el botón de cambio carril: van alrededor de la pista transmitiendo su ID fijo continuamente através del LED IR. De éste modo el LC sabe desde la PB si un determinado coche debe cambiar carril, y una vez que dicho coche se ha reconocido, el mecanismo del LC se activa.

Un coche oXigen en modo D132 manda su ID sólo cuando se pulsa el botón LC: en los demás casos (excepto por el cuenta vuelta), sigue girando sin ser detectado. Si, al mismo tiempo, la PB entiende desde su mismo mando que ese coche quiere cambiar de carril, y el botón de LC oXigen está comprimido, cualquier LC puede coger el ID infrarojo desde el coche, que puede así cambiar carril a voluntad.

Para contar las vueltas, sin embargo, Usted debe colocar un imán de FL oXigen justo antes del sensor de FL Carrera D132 para activar una transmisión de 200 mS del ID del coche, que será recogido por el sensor de FL. Así, un LC no debe ser colocado justo después de la FL, o los coches O2 cambiarán de carril.

Resumiendo, ¿cómo hacer? En primer lugar, con el software de Bootloader (0.12 y superior), o con el mando (2.13 y superior, coche 2.09 y superior) poner su coche O2 en modo D132. En seguida, programarlo con ID que oscile entre 1 y 6. Por último, conecte su mando Carrera en la PB slot correspondiente a dicho ID, bloquee el botón de LC en la posición 'ON' (por ejemplo, con una banda elástica), asegúrese de que los imanesestén colocados por debajo de la FL, y ya está listo.

Tenga en cuenta que los coches con chip oXigen no leen el protocolo digital Carrera desde los carriles, por lo tanto, no responden a los comandos de carrera start/stop desde la Power Base.

También es posible hacer correr más de 6 coches en la misma pista Carrera al mismo tiempo. Una vez más, es necesario colocar los imanes debajo de la FL. En éste caso los coches 7-20 deben ser los de O2 y el Carrera ID 4 está reservado para la extensión de O2. Usted necesita un mando Carrera enganchado al enchufe del mando n.4 con su botón de LC bloqueado. Luego, simplemente, poner los coches en el modo D132, fijarlos a ID 7 a 20, y hacerlos correr. En éste caso, se requiere un dongle oXigen para cuenta vuelta.
