Product Description
The RC-IESM (Internal Expansion Socket Module)
series of expansion cards for the Sierra Wireless
AirLink Fastrack Xtend FXT modems (hereafter
named Xtend only) contains an RF module which
interfaces to the UART serial bus inside the modem,
and an SMA connector for the external antenna. The
RF module is a Wireless M-Bus module, a ZigBee
module, or any module from the RC232 protocol
family from Radiocrafts. An embedded protocol
inside the RF module handles all RF communication
and only data payload and easy-to-use commands
are sent over the UART serial bus. The PCB is the
same for all modules which only requires different
BOM (Bill of Material) to support the various
protocols.
The Sierra Wireless Xtend M2M modems contain a powerful microcontroller handling the
GPRS/GSM/Edge communication and the serial communication towards the RF module. An
Open AT demonstration software (RTG) is available for download, enabling a fully working
demonstration gateway to be established. The software source code can be made available
and can be modified and tailored to fit numerous applications.
