Il Digitale Terrestre secondo Eurotek

Mainframe mod. EK – MFR/1

The Mainframe is the core of the “ALL4DIGIT” system, it is the base device that thanks to a new flexible and modular platform which allows simultaneous use of different kind of boards inserted in its inner part in completely reconfiguration way. All the inserted boards inside the device are automatically identified by the integrated operative system, that fits the function of the keyboard and the visual information available on the colour display placed in the frontal panel. Inside the Mainframe a real time clock (RTC) works as a temporal reference for the storage of the alarms occured in the system.

Whatever alarm of each board is visualized on the display in a sequence mode: a red led (ACTUAL) on the frontal panel show that an alarm is in progress as well as a yellow led (STORED) indicate the memorization of previously happened alarms. Thanks to this function the user will be able to examine a log file, stored inside the Mainframe and verify the type of alarm, the time and date in which the alarm occurred as well as the time and date in which the alarm stopped. The setting operation of every single board can be done locally on the keyboard, or by remote sites thanks to the use of Ethernet 10/100 base T interface located in the power supply section (EK – PWS /x) that allows a remote connection to the web.

Inside the Mainframe re-configurable connection lines are inserted; they allows the connection among all the slots inserted in the system leading therefore to an interconnection of the signals that transit from one board to another one without the necessity of using an uncomfortable external connection.

In order to set the operating functions of the system there are two different password levels: one in reading mode only and the other one in reading/writing mode. Operating in this system it will be possible to deny the access in writing mode to unqualified users meanwhile the configuration settled will appear on the screen giving at the same time the chance of checking how the system works.
