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.
