The new Maxon SD-160 Series RF Data Link
Telemetry Radio
delivers reliable 2-way communication & remote control for a variety of
application needs. Available as VHF (SD-161) or UHF (SD-164) with 2
Watts and 16 channels. The SD-160 Series provides reliable data or voice
communication at all times. Crystal clear audio quality makes the SD-160
Series an ideal radio for golf course and emergency call boxes. When
paired with the optional GMSK or FFSK modem board, the SD-160 Series
transmits and receives data for wireless security systems, or it can be
used in conjunction with police mobile data terminals for license tag
checks. The optional GPS receiver turns the RF data radio into an
Automatic Vehicle Location system for tracking fleet movement and
communicating data directly to a computer
