Introduction
The RM24100D radio modem acts as a wireless serial cable replacement and can wirelessly connect various devices
together for a large range of applications. The RM24100D radio modems operate in the license free 2.4GHz ISM
(industrial, scientific, medical) band and is capable of achieving long range line-of-sight communications up to 1km. With
its durable polymide industrial din rail mount enclosure and industrial temperature grade electronics makes the unit
perfect for industrial automation/SCADA systems and remote data acquisition. The RM24100D includes DSSS (Direct
Sequence Spread Spectrum) radio technology to ensure reliable communication in noisy environments. The RM24100D
also includes 128 bit AES encryption technology for secure wireless data transfer.
The RM24100D can operate in a peer-to-peer (no master/slave dependencies), point-to-point, point-to-multipoint,
multipoint to multipoint and repeater network topology.
