This article describes how the AlphaCom can be integrated to the digital radio system Mototrbo from Motorola.
Functionality
What functionality you get depends on whether the AlphaCom and the radio communicate via serial data or not. If more than groupcall functionality is required, then a specific USB to Serial adapter is necessary (XCMP converter). The adapter is connected to the serial port on the IP-ARIO and to the accessory port on MOTOTRBO radio (USB).
Without XCMP converter
- Without the XCMP converter only basic groupcall is supported (no caller ID)
With XCMP converter
- With the XCMP converter and EventHandler configuration the following functionality has been tested:
- Groupcall in fixed group (M-key is PTT)
- Semi-duplex private call to selectable MOTOTRBO radio
- Incoming group and private call to predefined intercom station
- Predefined text messages to MOTOTRBO radio
- Call Alert to MOTOTRBO radio
- Display of Caller ID
- The following functionality has not been tested yet:
- Incoming Emergency Call
- Talkgroup change
- Remote monitor (listen in at radio)
The following functionality is currently not supported:
- Receiving of text messages from AlphaCom (radio firmware issue). Which means that the radio handsets cannot receive for instance Call Request
Most suitable radio is DM3600 (display model); for basic functionality also DM3400 can be used.
Connections:
- The Mototrbo radio is connected to IP-ARIO with:
- RX audio to Radio IN (Motorola 770 mV nom.)
- TX audio to Radio OUT (Motorola 80 mV nom.)
- PTT to RCO output (active low)
- Audio is asymmetric, DC-block capacitor is required in TX audio line to radio.
- Ignition input of the radio needs to be connected to +12V to power-up the radio automatically.
