Motorola GM-Series radios

We have made virtual control heads for the advanced radios in the Motorola GM-series.
This means that you can remote control the radio from “anywhere” using the Internet or other IP connection.

The virtual control head gives you full control of the radio, just as if you were sitting in front of it. All buttons can be accessed from your touch screen, with the mouse or by short cuts on the standard keyboard.

In order to connect to the radio you should take away the standard control head from the radio and install the remote head. (It will not work through the microphone connector on the control head)

All audio and data goes through the front connector.

Through the back connector of the radio only external alarm is connected. Standard is pin 4 programmed for external alarm low output. Mimer will through this know that a selective call has been placed to the radio and activate its sel call function; blinking green name bar and audio alert.

The radio SHALL NOT be wired for “ignition sense” to auto start. The Network Interface will restart the radio if power has been cut and then restored.

The radios that we remote control are known in Europe as GM360, GM380 and GM1280. They have other names in other parts of the world. See table below for numbering in Asia and America.

Older Motorola radios

Other Motorola radios like the GM340 or CM-series radios can be connected through audio and PTT, without a virtual control head. We have ready made interfaces and cable kits for this.

It will give you audio and PTT functionality, but no virtual control head or channel control.

Please see the page with generic interfaces.

Examples of use:

  • Local use when several dispatchers want to share one radio
  • Remote use where a dispatcher at one location want to talk to radio users at a different location
  • CrossPatch between Marine radio channels and other two way radios, like analogue, IDAS, DMR, Tetra or MPT
