4.3.2 VIP Input Connections
The VIP input pins are only available on the back of the control head (remote mount). These
connections control inputs from switches. One side of the switch connects to ground while the other
side connects to a buffered input on the control head. The switch can be normally closed (NC) or
normally open (NO) depending on the configuration of the VIP inputs. There are three VIP input
connections, as follows:
NOTE: Remote Mount requires the VIP cable to be attached to J400.
MCH installations require the VIP inputs to be connected to the head assigned ID #1. See
Section 2.2.2.4 for further information.

APX mobile radios equipped with the following features are capable of transmitting
automatically, even if the radio is turned off:
• Automatic Vehicle Location
• Other Special Data Products
All APX mobile have accessory connector pins 14 and 15 connected together to allow
the radio to power down. Opening this connection by REMOVING the accessory
connector, or otherwise failing to maintain a normally closed path, could, if left
unchecked, drain the vehicle battery, and possibly cause transmissions to occur.
