RPM3B
UHF Radio Packet Modem
Issue 1, 01 August 2012
The UHF Radio Packet Modem (RPM3B) is a low cost intelligent radio packet modem that
enables a two way radio network/link to be simply implemented between a number of digital
devices. The RPM3B uses addressable data packets with error checking, packet
acknowledgements and retransmissions to achieve a reliable transparent wireless data link.
Built for ease of use and rapid installation, the serial interface ensures direct connection to
microprocessors or to RS232 port via RS232 driver while remote configuration enables post
installation setup of the modem.
