VHF Narrow Band FM Radio Packet Modem

page 1

The VHF Radio Packet Modem (RPM1) 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 RPM1 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.
