Radio Modems

Model RM24100D is a rail mount 2.4GHz radio modem to transmit and receive serial data. This module operates as a wireless serial cable in the licence-free 2.4GHz ISM band with line-of-sight communications up to 1km. Direct Sequence Spread Spectrum radio technology makes for reliable communications in electrically noisy environments. The RM24100D may be used in peer-to-peer, point-to-point or point-to-multipoint networks. These units are housed in rail mount polymide housings and are supplied with 2.1dBi dipole antennae. The radios meet CE and C-Tick EMC and EMI requirements and are configurable to limit the maximum transmit power output level.

RM24100D wireless serial modems are also ideal for use with Instrotech digital indicators and large digit displays. Large displays may be used to repeat data transmitted from remote panel meters or used as slaves displaying data from computers or PLC's with serial output. Instrotech rail-mount serial radio modems are available in 3 variants:

  • RM24100D-232 for RS232
  • RM24100D-485 for RS485
  • RM24100D-422 for RS422


Features:
  • 6-30VDC switch-mode power supply
  • Approximate 1km line-of-sight range
  • Easily re-configurable via free software
  • Licence free 2.4GHz frequency ISM band
  • Approximate 100m indoor / urban range
  • Serial data rates of 1200 to 115200 BPS
  • Available as RS232, RS485 or 4-wire RS422
  • Transparent wireless serial link cable replacement
