The Kantronics KPC-3+ is engineered for dependable and versatile digital communications. This unit reflects many years of Kantronics experience and is built with an eye toward emerging applications. The KPC-3+ can fill a variety of roles. In use around the world, Kantronics Packet Communicators set the standard by which others are measured!
As a single-port radio modem/TNC compatible with the characteristics of UHF/VHF transmission bands, the KPC-3+ can be paired with a UHF/VHF radio to serve the following functions and applications:
You can carry a KPC-3+ into 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 flexible power requirements (6 ~ 25 Vdc) allow for maximum versatility. You can achieve many hours of use by installing a 9 volt battery inside the KPC-3+. Battery life can be extended by disabling the LED displays through a simple keyboard command.
