Kantronics' radio modems (also known as packet modems, since they are most frequently used in packet-based communication modes) convert radios (HF/VHF/UHF) into digital communications devices especially well suited for packet radio communications. Hook up an ordinary PC, a Kantronics radio modem, and your radio, and you can send and receive e-mail, transfer files, monitor remote operations, and use numerous other packet radio applications. Connect a GPS receiver to a Kantronics radio modem and a radio to create a location transmitter for tracking applications. Use the modem's A/D inputs to remotely sense critical conditions such as temperature, pressure, etc.
 | As shown in the diagram, a radio modem/TNC extracts digital data from the analog (received RF audio) signal of a radio. The digital data is then processed according to the modem's current mode and protocol. Successfully received data can be stored for later access, passed on to a local computer, or retransmitted to other sites, extending the range of a radio network. The radio modem also encodes and packetizes data from a local computer or GPS receiver (or analog sense inputs). Encoded packets are then sent to the radio for transmission, with the modem enabling the radio's transmit mode. |
The TNC (Terminal Node Controller) capabilities in Kantronics radio modems enable you to "plug into" radio networks. With a Kantronics radio modem/TNC, your radio becomes a fully operational network node, able to communicate on virtually all popular protocols (see the table below). Set up a simple, efficient radio network with K-NET™ or connect to the Internet with TCP/IP.
Kantronics offers six models of Radio Modems/TNCs. The following table shows the features that differentiate the models:
| Feature Set | VHF/UHF Single Port | VHF/UHF Dual Port | VHF/UHF/HF |
|---|---|---|---|
| Basic | KPC-3+ | KPC-9612+ | |
| Enhanced (includes transparent modes especially useful in commercial applications) | KWM-1200+ | KWM-9612+ | KAM-XL |
| Mobile Enhanced (available with built-in GPS module, voice activated data burst, and other enhancements for mobile operation, all in a compact new form factor) | MT-1200 |
