The KWM-1200+ Single Port and the KWM-9612+ Multi Port High Speed wireless modems. Both are engineered for dependable and versatile digital communications in the commercial operating environment. Kantronics has developed the KWM units to meet the needs of today, with an eye toward emerging applications. Able to communicate in a variety of formats, including TCP/IP, LSUB and TUP, the KWM units are seamless and transparent radio link substitutes. KWM units can also operate as a data-operated switch (DOX). KWM units can fill a variety of roles. They are well made, engineered for dependability and low in cost. It's no wonder Kantronics units are in use around the world.

KWM-1200+ Applications Include:

"Keyboard to keyboard" communications
Digipeater (suitable for remote locations)
Electronic Mail Box
Local area node
Remote control devices
Remote access of telemetry data
BBS operations and message forwarding
GPS position transmitting and tracking (NMEA-0183 data required)
Data storage and retrieval
Send/Receive Files
The KWM-1200+ can be used in the field with a radio to form a mobile data terminal, or (with the addition of an external GPS receiver) a GPS mobile "tracker". Its broad supply voltage range (DC 6 ~ 25 V) allows for maximum flexibility.
