RIC-2 - Repeater Interoperability Controller

MIDIAN ELECTRONICS:  Two Repeater Interoperability Controller

Features

• 2175 Hz notch filters

• 3 year warranty

• Cost-effective

• Interoperability and steering control modes

• Interoperate 2 repeaters

• Uses standard EIA sequential tone format

Description

The RIC-2 is a tone remote adaptor that allows two repeaters connected by a dedicated phone line, telemetry link or microwave to key one another. For instance when Repeater A receives a signal from a portable or mobile radio, the repeater gives a COR signal to the RIC-2. The RIC-2 will generate 2175 Hz high-level guard tone, function tone and low-level guard tone to Repeater B's RIC-2 to key Repeater B and re-transmit the audio coming from Repeater A. Function tone F4 is used to have Repeater A key Repeater B and function tone F5 to have Repeater B key Repeater A.

Additionally, a tone remote controller can be connected to the two RIC-2 units for steering control mode. In addition to the scenario above, the tone remote controller can transmit to Repeater A using function tone F1, Repeater B using function tone F2 or simulcast to both Repeaters A and B using function tone F3.

Applications

The RIC-2 is used in systems that need interoperability between radios users on different repeaters.

Installation

The two RIC-2 units are connected by a dedicated phone line, telemetry link or microwave to key one another. The RIC-2 looks for a COR indication from the repeater to generate the keying tones.
