Overview

KWM-9612+ front view

Kantronics, a pioneer in wireless data communications, now offers 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, 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-9612+ 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
  • Send/Receive Paging signals*
  • 1200 <--> 9600 gateway operation*

       * Applications using features of the KWM-9612+ not found on the KWM-1200+.

The KWM-9612+ 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 V to 25 V) allows for maximum flexibility.
