The Model 250 is a tone termination panel that includes features typically only found in high-end remote control stations. It provides a means of connecting a base station radio to industry standard tone remote encoders, such as Zetron�s radio remotes and dispatch consoles.
The Model 250 Tone Remote Adapter connects to an audio circuit or leased line from the tone remote and to the unique interface of the base station radio. The Model 250 includes integrated setup utilities that reduce the need for service equipment. Designed for fast installation and easy setup, it can be configured in the field without tools.
TONE REMOTE CONTROL SUMMARY
Tone remote equipment uses the Tone
Remote Control (TRC) Protocol to send control information to the
Model 250. The Model 250 in turn translates the tone remote commands
into base station radio control.
