Table 7 Vip Output Connections; Table 8 Vip Input Connections - Motorola Spectra Service Manual

Remove the two 16mm self-tapping screws on the
control board. Remove the back of the control unit
housing. Remove the black gasket around the switch
and set it aside. Remove the shields from the top and
bottom of the control board. All components should be
easily accessible.
When working with chips and SOT parts, use
extreme caution when heating. Never reuse a chip
or SOT part; always replace with correct Motorola
parts.
2. Reassembly of the Control Unit
Ensure that the orange gasket is still around the
outside of the control cable mini D connector. If it was
removed, replace it, ensuring a snug fit to the PC board.
Replace the gasket around the power switch. Replace
the shields on the top and bottom of the control board.
Place the control board in the back housing, being care-
ful to put the toggle switch arm in the proper position in
the ON/OFF button actuator.
Torque the two 16mm self-tapping screws to
6-8 in.-lbs. Ensure that the ON/OFF actuator slides
back and forth easily. Carefully check to see that all
buttons are still in place, then place the display board in
the front housing. Torque the five 8mm self-tapping
screws to 6-8 inch-lbs. Ensure the black gasket is
around the outside groove of the front housing. When
mating the front and back housings, ensure the flex
cable slides behind the control board and is not pinched.
Torque the two 30mm slotted screws to 9-10 in.-lbs.
D. Vehicle-Interface Ports
The vehicle-interface ports (VIP) allow the control
unit to operate outside circuits and to receive inputs
from outside the control unit. There are three VIP out-
puts that are used for relay control. There are also three
VIP inputs that accept inputs from switches. See the
cable kit section for typical connections of VIP input
switches and VIP output relays.
1. VIP Output Connections
The VIP output pins are located on the back of the
control unit below the area labeled VIP. These connec-
tions are used to control relays. One end of the relay
should be connected to switched B+, while the other
side is connected to a software controlled ON/OFF
switch inside the control unit.

The relay can be normally-on or normally-off,
depending on how the VIP outputs are configured. The
control unit provides for three of these VIP output con-
nections. See Table 7.
The function of these VIP outputs can be defined by
field programming the control unit. Typical applications
for VIP outputs are external horn/lights alarm
and horn ring transfer relay control. For further informa-
tion on VIP outputs, see the control unit programming
manual.
2. VIP Input Connections
The VIP input pins are located on the back of the
control unit below the area labeled VIP. These connec-
tions are used to accept inputs from switches. One side
of the switch is connected to ground, while the other
side is connected to a buffered input to the control unit.
The switch can be normally-closed or normally-open,
depending on how the VIP inputs are configured. The
control unit permits three of these VIP input connec-
tions. See Table 8.
The function of these VIP inputs is defined by field
programming the control unit. Typical applications for
the VIP inputs are for a foot switch or a horn ring switch.
For further information on VIP inputs, see the control
unit programming manual.
E. Power Connections
Use only Systems 9000 cable kits. Connection
to other cable kits or control panels may cause
electrical damage.
Replace the fuse in the in-line fuseholder of the red
power cable coming from the radio in the trunk. Con-
nect the green (and/or orange) fused wire(s) coming
from the control unit to the ungrounded terminal (or
source) of the battery.
Pull all excess cabling into the trunk. Clamp the
cables to the vehicle body or chassis with the cable
clamps supplied. Drill 1/8" mounting holes; attach the
clamps with four #8 x 3/8 in. tapping screws and four
1/4 in. lockwashers. Ensure that all in-line fuses are
installed.
