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.
