Overview

This device enables communication between radios operating on two different frequency bands, supporting the conversion function from two IP telephone/ordinary telephone lines to two radio audio interfaces. It features three working modes: a one-to-one direct mode from telephone to radio, a conference mode from the first line to both radios, and a conference mode from the second radio to both radios. The IP telephone function of this device supports interconnection with SIP protocol servers and terminals. The ordinary telephone interface can interface with mainstream telephone exchanges in China. The IDM_RG2000 series devices mainly come in two versions, as follows:

Green

Device Operation Indicator

When the device CPU operates normally, this indicator blinks on and off at 250ms intervals; when abnormal, it remains steadily on or steadily off.

LED1

Green

Channel voice indicator

This LED lights up when there is voice activity on the telephone channel; it turns off when there is no voice activity.

LED2

Green

Channel audio indicator

This LED lights up when there is audio on the radio channel; it turns off when there is no audio.

The DIP switch controls the device operating mode, allowing users to configure settings according to the application scenario. The DIP switch usage is described in the table below:
