UNIVERSAL DEVICE CONNECTOR (UDC)
The Universal Device Connector (UDC) provides connections for external
accessories such as a headset or a speaker-microphone and for programming
cables. The UDC is located on the right side of the radio (opposite the PTT
Button). When the radio is locked in a vehicular charger the UDC provides
the audio and control connections between the radio and the vehicular charger.
The UDC facilitates programming and testing the radio. The UDC pins
perform different functions depending on the accessory attached to the UDC.
