This article is a stub. You can help AlphaWiki by expanding it.

This article describes how the AlphaCom can be integrated to the digital radio system Mototrbo from Motorola.

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)
When more than groupcall functionality is required than a specific USB to Serial adapter is necessary (XCMP converter); the adapter is connected to serial port on the IP-ARIO and to the accessory port on MOTOTRBO radio (USB).

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.
