Cambridge, UK Arcom has released a versatile PC/104 baseboard suitable for adding cellular wireless communications to any embedded Machine-to-Machine (M2M) system. The WEB-Telemetry (Wireless-Embedded-Baseboard for telemetry) includes sites to locate several leading iDEN and GPRS/GSM cellular modems from Motorola, Sony Ericsson and Siemens. The board also serves as a wide input (10 to 30 V) regulated power supply for the PC/104 processor board, as well as providing an integrated Trimble GPS receiver module and digital inputs for status signals. PSU, a modem carrier and a GPS receiver card are combined into a single 155 x 100mm board with I/O connectors conveniently located along one edge of the board. The onboard power supply can supply up to 2.5 A at 5 V, 2.5 A at 3.6 V and optionally, 250 mA at ±12 V. The WEB-Telemetry can be fitted with GPRS/GSM modems from Sony Ericsson (GM47/48) and Siemens (MC35i), as well as the Motorola iO200 and iO1500 modems used for the Nextel iDEN network. The iO200 has been designed with integrated GPS functionality and offers a low cost solution for M2M applications using the Nextel data network. The WEB-Telemetry provides the matching connectors, power supplies and where appropriate, the SIM card (Subscriber Identity Module) carrier for plug-n-go operation. The board can be fitted with a low power Trimble LassenSQ GPS receiver to provide positional data and an accurate 1 pulse per second synchronized to an atomic clock (UTC).
