Module
The CM2201N is a 916.5 MHz transmitter module designed to monitor industrial alarm
sensors. Communication range in an “open field” environment is typically 100 meters.
The CM2201N combines RFM’s very low-current SAW resonator stabilized transmitter
technology with low-power microcontroller technology to achieve long battery life. The
module is compatible with RFM’s miniMESH
TM
network protocol, which provides add-on
“plug-and-play” multicast mesh network routing. The CM2201N is certified for operation
under FCC 15.249 regulations.
