11. CABLES AND CONNECTIONS
11.1 ACCESSORY CABLES 14002-0174-50 AND 14002-0174-70
Accessory Cables 14002-0174-50 and 14002-0174-70 connect to the 44-pin I/O connector on the rear of
the radio. It breaks out into several smaller standardized connectors, allowing straightforward access to
external I/O interfaces provided by the radio. The cable also shortens radio removal and re-installation time
when required. The cable is shown in Figure 11-1 below. The cable’s 44-pin D-subminiature connector
(P8) mates with the connector on the rear of the radio.
Use caution when connecting any external device to the radio via its 44-pin I/O connector. If
an external device has its own DC power source/cable (i.e., is powered separately from the
radio), both the radio and the external device must be properly grounded to the vehicle before
connecting the two units together and before making a positive (+) DC power connection to
either unit. Otherwise, equipment damage may occur.
