11 OPTIONAL CABLES
11.1 M5300/M7300 OPTION CABLE CA-012349-001
M5300/M7300 Option Cable CA-012349-001 connects 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 that mates
with the connector on the rear of the radio is identified P1.
P2, the cable’s 2-pin connector, provides connections for an external speaker in a front-mount M7300
mobile radio installation. See Section 9.1 (page 64) for connection instructions. P2 is not
used in a
remote-mount radio installation. In a remote-mount radio installation, the audio amplifier in the CH-721
control head drives the external speaker. In this case, the speaker connection is made at the rear of the
control head.
