SPM2-433
UHF SpacePort Modem
The SpacePort Modem (SPM) is a low cost highly integrated intelligent radio packet
modem that enables a radio network/link to be simply implemented between a
number of digital devices. The SPM uses addressable data packets with error
checking, packet acknowledgements and retransmissions to achieve a reliable
invisible 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.
