Description
This pin is the same as pin 6. A jumper exists to
change this pin to VIP_IN 2 at 3.3 volt levels.
Audio spoken from the operator which goes into
legacy siren and legacy VRS. Jumpers exist on the
TIB to change this pin to AUX_MIC, and MIC_IN.
MIC_IN routes to the transceiver MIC_HI input.
Input used to detect emergency activation. To use
this input, a shorting jumper on the TIB, which
grounds this input, must be removed. Once the
jumper is removed, emergency operation is possible
at either this connector or at the J2 connector.
Part of the Motorola SB9600 communications bus to
connect external devices.
HLN1454B has AUX_MIC as the default state of this
pin. HLN1454C has VIPOUT_1 as the default state
of this pin. The nominal input level for AUX_MIC is
80 mVrms for 60% deviation when used for
motorcycle, but can also support 300 mVrms for
future APCO accessories. The DC impedance is
1560 ohms and the AC impedance is 560 ohms, 1
Vrms max 9V DC with no input load. Jumpers exist
on the TIB to change this pin to MIC_IN,
DAC_AUDIO_OUT, and VIPOUT_1 (passthrough).
MIC_IN routes to the transceiver MIC_HI input.
Connecting this line to the vehicle ignition will allow
CPS ignition features such as "ignition required for
turn on" to be used. Connecting this line to the car
battery will defeat CPS ignition features.
Part of the 4-wire RS232 interface to external data
accessories, programming cables, etc. An output
normally +9V no load. A jumper exists on the TIB to
change this pin to VIPOUT_2 (passthrough).
Part of the Motorola SB9600 communications bus to
connect external devices.
This voltage is available when the radio is switched
on.

Used along with SPKR+ to connect an external
speaker. The audio PA is a bridge amplifier with a
3.2-ohm minimum impedance.
