2.1.3.2 Remote Mount: Power, Ignition, and Emergency Cable Installation

The single control head O2, O3, O5, O7 or O9 remote mount configurations receive power from the
J200 connector's red and black wires. The yellow wire at J200 is one ignition sense wire. On mid
power radios, the J2 and J600 connectors can also be used for ignition sense. On high power radios,
the J200 yellow wire or the J600 connector can be used for ignition sense. If the HLN6863 is
attached at J100 of the O2, O3, O5, O7 or O9 control head, the "thin red" wire will NOT function as
an ignition sense wire, since the J100 connector has no ignition sense electrical connection.
NOTE: It is incorrect for installation to attach ignition sense at more than one wire or connector.
Refer to
The O3 control head receives its power down the CAN cable, and detects the ignition state by the
ignition sense pin at either J2 or J600. On mid power radios, the J2 and J600 connectors can also be
used for ignition sense. On high power radios, only the J600 connector can be used for ignition
sense.
In Multi-Control Head installations, the yellow ignition wire must be connected to the head assigned
ID # 1. See Section 2.2.2.5 "Setting the Initial Control Head ID" on page 2-29
In remote mount O2, O3, O5, O7 or O9, an Emergency jumper to ground is placed by default on the
TIB (JU344) so that there is no need to attach a cable with an emergency accessory at either J2 or at
J600. This jumper must be removed if an emergency accessory (footswitch or button to Ground) is
installed at either J2 or J600 (or J626 on the accessory cable) locations. If the jumper JU344 is
removed but no emergency accessory is installed, the radio will power-up incorrectly into emergency
mode all the time. Refer to
The design of the control head is different compared to the transceiver, therefore it is also NOT
necessary to attach HLN6863 at J100 to prevent accidental emergency operation. The control head
uses an edge-detect, not a state-detect like on the transceiver, so mounting of HLN6863 is not
mandatory.
