Technology deployed
Bee wireless modem in a dual in-line (through-hole) package the size of a quarter. The host end of the network can consist of an Ethernet gateway or an embedded board stack with its own RS-232 serial port ZigBee adapter. ZigBee is an affordable wireless alternative to WiFi where large numbers of DAQ endpoints exist, and yet long range is preserved due to the low transmit data rate and duty cycle. Radios are also available as stand-alone components to be used with any processor or microcontroller. ZigBee chip vendors like Freescale, TI, STMicro, Atmel and Samsung often sell integrated radios and microcontrollers with between 60 Kbyte and 256 Kbyte flash memory. The ZigBee software stack is available from the chip vendors or third parties. Visit www.zigbee.org to learn more. The SUMIT interface is the ideal multi-module board-level architecture for either of the wireless standards, since PCIe x1 interfaces to off-the-shelf PCI Express Mini Card Wi-Fi adapters and because LPC, SPI and I2C are easy to interface to low-speed ZigBee modems. Off-the-shelf LPC quad UART chips cost only a few dollars. The 90 x 96 mm PC/104 stackable board market benefits from the aforementioned new developments in performance, flexibility, connectivity and data acquisition options while retaining its ruggedness, reliability, industrial temperature range and long-term availability. SUMIT-ISM is the only form factor that allows PCI Express, USB, LPC, SPI, I2C and ISA (PC/104 bus) as expansion interfaces off a single host computer, which minimizes the size, cost and power consumption of new DAQ deployments. Legacy I/O support
is a common requirement in existing systems. Many applications require additional I/O as well, so PC/104 is the low-power, off-theshelf choice compared to COMs with custom carriers. As a result, SUMIT-ISM is the only viable architecture for these types of data acquisition environments. Using state-of-the-art, low noise 16-bit A/D and D/A converters with no calibration required, gives a shot in the arm to the PC/104 DAQ market. This clean, simple design yields smaller size, lower cost and much better accuracy by avoiding error-prone manual calibrations. The PC/104 bus platform provides a power-efficient and long-lifecycle 16-bit data path for these converters. And now SUMIT-ISM DAQ cards allow even higher data acquisition in the same, stackable, small form factor. This is attractive to both integrators and OEMs alike who need to integrate the PC and the DAQ circuitry together for their next designs, regardless of whether the host connection is wired or wireless.
