View of the Talon Data Radio


The Kantronics Talon UDC (Universal Data Controller) Data Radios combine the functionality of a radio modem/TNC with a built-in UHF or VHF radio transceiver. With the optional I/O board, the Talon UDC also provides more analog and digital I/O lines than Kantronics radio modems. This makes the Talon UDC an excellent choice for remote sensing and control applications that require simplicity, compactness, and reliability. In addition, the Talon UDC provides a cost-effective solution for companies seeking to minimize asset management expenses.

The Talon UDC is available with an optional built-in GPS receiver, which converts the Talon into a stand-alone location transmitter. This makes the Talon with GPS a great choice if you need to both track the location of your assets and monitor/control their operation, and automatic vehicle location (AVL) applications in general.

Other Talon UDC applications include:

  • Traffic control
  • Fleet management
  • Industrial process control
  • Water management
  • Utility monitoring
  • Public safety
  • Text messaging
  • Emergency management

No matter what level of data control you need - now and in the future - Kantronics can help you make your business more profitable with superior control of valuable spectrum. Kantronics Talon UDC exceptional design allows for reliable point to point, or point to multi-point communications under less than perfect conditions and excellent performance under adverse signal paths.

Talon Companion Software

Free point-and-click Talon Configuration Utility (ZIP, 345k. Requires Microsoft .Net framework to run. See the readme.txt file in the .zip file.)

Free user-configurable sample Telemetry Program (ZIP, 353k) for use with our Talon data radios. The program requires Microsoft .Net framework to run. See the readme.txt file in the .zip file. While you obviously won't see live data unless you have a Talon data radio, you can configure the sites and displays without the radios.
