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
