RPM1
VHF Radio Packet Modem
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.
