3 Description
This section provides a general description of
the Opticom™ GPS system and a detailed
description of the vehicle equipment.
3.1 Opticom™ GPS System
The Opticom GPS system assists authorized
priority vehicles through signalized
intersections by providing temporary right-of-
way through the use of common traffic
controller functions.
The Opticom GPS system consists of the
following matched components:
Vehicle Equipment —
Radio/GPS unit containing a GPS receiver
and a 2.4 GHz transceiver
Radio/GPS antenna
Control unit
Intersection Equipment —
Radio/GPS unit containing a GPS receiver
with antenna and a 2.4 GHz transceiver with
antenna
Or Radio/GPS unit containing a GPS
receiver and a 2.4 GHz spread spectrum
transceiver with a separate Radio/GPS
antenna
Phase Selector
Card Rack/Input File
Auxiliary Interface Panel
Auxiliary Harness
The vehicle equipment is mounted on the priority
vehicle. Its GPS receiver acquires position
information from the constellation of GPS
satellites. This information is used to compute
the location, speed, and heading of the vehicle.
This information, along with a priority request and
the state of the vehicle’s turn signal, is broadcast
using the 2.4 GHz transceiver.
The intersection equipment receives the radio
transmission from the vehicle equipment. The
intersection equipment then compares the
information being received from the vehicle to
the parameters stored in the intersection
equipment’s memory. If the vehicle is heading
toward the intersection in a predefined
approach corridor, is requesting preemption
and has met all other programmed
parameters, the corresponding phase selector
output is activated. This output is connected to
the traffic controller preemption input. When
activated, the controller cycles to grant a green
light to the requesting vehicle or holds the
green allowing the vehicle to pass through the
intersection.
The card rack/input file provides the power and
logic wiring for the phase selector, which plugs
directly into a slot in the unit.
The auxiliary interface panel provides additional
connections for monitoring green phases and
also provides additional priority control outputs.
The green sense harness can be used to
provide additional connections for monitoring
green phases when the auxiliary interface panel
is not required.

proper length.
5. Strip approximately 3 inches of the outer
jacket from the end of the cable. Be careful
not to cut the wires inside.
6. Strip 1/4 inch of insulation from each wire.
Note: It is very important not to strip too
much insulation, which may lead to short
circuits; or too little insulation, which may
prevent the wire from making good
contact.
7. Place each wire into the appropriate terminal
in the 10-pin terminal block located on the
back of the control unit and tighten the screw
to secure the wire. The label on the terminal
block shows the color for each wire. Table

5.5.1 Turn Signal Sensing Connections
The turn signal sensing circuit operates by
detecting the change of state or flashing of the
vehicle’s turn signal circuits. If the turn signal
sense circuit detects both the left and the
right signal sense lines changing or flashing,
the vehicle equipment will transmit that it is
going straight.
This can be verified by monitoring the turn signal
inputs with the View Inputs Sensing screen or
vehicles heard screen in ITS Explorer.
1. Activate the left turn signal.
2. Press the brake pedal.
3. If you see the right (opposite) turn signal
sense change from active to inactive or vice-
versa. You will need to find another place to
connect to the vehicles turn signals.
Note: there is a 3 second delay before the
turn signal status will register. Press the
brake pedal several times and hold it for at
least 3 seconds.
This occurs because; in some vehicles the brake
light bulb is shared with the turn signals. If this
is the case, applying the brakes while either turn
signal is on will cause the turn signal sensing
circuit to think that both inputs are active and
cause the vehicle to transmit that it is going
straight.
Therefore it is recommended that the yellow and
green turn signal sense lines be connected only
to the front turn signal wires.
1. Connect the yellow wire from the harness to
the vehicle’s front left turn signal line.
2. Connect the green wire from the harness to
the vehicle’s front right turn signal line.
5.5.2 Additional Vehicle Connections
1. Connect the white wire to a switch that
actuates when the driver reaches the scene
and steps out of the vehicle. For instance,
this could be a door switch. The switch may
provide either +12 VDC or a ground. You
will need this information to set the Operating
mode (see Section 6.1, Configuration Setup
and Checkout).
Note: If the white disable line is not to be
used it is recommended that this wire be
connected to Ground. The disable mode
should then be set to Ground -> 12VDC and
non-latching.
2. Connect the blue wire to one of the provided
fuse holders. Connect the other end of the
fuse holder as described in either step a or b
below.
Do not install the fuse yet.
a. Connect the fuse holder to a point that
provides +12 VDC only when the lightbar is
turned on. This enables the driver to activate
the system when the lightbar is on by
pushing the ON/OFF switch on the control
unit to the ON position.
b. Connect the fuse holder to a point that
provides +12 VDC when the ignition switch is
in the RUN position. This enables the driver
to activate the system when the ignition
switch is on by pushing the ON/OFF switch
on the control unit to the ON position.
3. Install the fuse rating label on the blue wire
near the fuse holder.
4. Connect the red wire to the provided fuse
holder. Connect the other end of the fuse
holder to a +12 VDC power source that
provides at least 2 amps at all times. In
order for the GPS receiver to maintain an
accurate location, the receiver requires a
constant +12 VDC power source.
GTT recommends using a direct connection to
the battery. If this is not possible, use a terminal
block with a direct connection to the battery.
Do not install the fuse yet.
5. Install the fuse rating label on the red wire
near the fuse holder.
6. Connect the black wire to vehicle chassis
ground (DC–). Again, it is recommended
that this connection be made directly to the
battery or to a terminal block with a direct
connection to the battery.
7. Verify that the control unit on/off switch is set
to the OFF position.
8. Inspect all connections and verify that the
wiring is complete and accurate as described
in this installation manual.
9. Install the fuses (2A, 250V) in the fuse
holders.
10. Connect the vehicle’s positive battery cable,
then connect the negative battery cable.

5.5.3 Low Priority
When Opticom™ GPS vehicle equipment ships
from the factory, the priority level (High or Low)
is preset. The user cannot change this priority
level. However, a high priority vehicle may be
set to temporarily be a low priority vehicle. This
feature is useful for traffic department
maintenance vehicles that maintain Opticom
GPS intersection equipment where both high
and low priority vehicles operate.
Low Priority Connections:
The vehicle interface harness contains a brown
wire that when connected to +12 VDC will cause
the vehicle unit to temporarily broadcast that it is
a low priority vehicle (see Table 5-3).
1. Connect the brown wire to one side of a
switch (not provided) and connect the other
side to +12 VDC.
2. Install an in-line fuse holder with a 2A, 250V
fuse (not provided).
3. When you activate the switch, the vehicle
will be a low priority vehicle until the switch
is deactivated.
Do not connect the Brown wire if
you do not want to use the mode
described above.
This action may be observed using the Vehicles
Heard section of ITS Explorer. Refer to the GPS
Vehicle Configuration section of the Opticom™
GPS System Operation Manual.
5.5.4 Probe Priority/GPS always out
The user has the option of activating the
Opticom GPS vehicle unit in a mode that will
allow the vehicle to transmit its position
information and output GPS data via a com port
without requesting TSP/preemption. This is
done by connecting the gray wire to +12VDC.
When +12 VDC is applied to the Gray wire, the
vehicle equipment will broadcast that it is in
Probe priority (will not request TSP/preempt).
Then one of the communication ports may be
configured to output GPS data in the NMEA
format. This data may be sent to other onboard
devices or computers to display the vehicles
current position speed and heading.
Notes:
1. See the Technical Bulletin “Vehicle
Connections and Configuration to obtain
GPS serial data for other Devices” or
section 9 of this document for details on
how to make these connections.
Do not connect the Gray wire if you
do not want to use the mode
described above.

2. Using the Diagnostic Activity window, open
the View Inputs Sensing window and activate
the left turn signal followed by the right turn
signal. Verify that the vehicle equipment
detects each input. You may also use the
vehicles heard window.
If both signals are being detected when only
the left or right signal is activated, it may be
necessary to connect the turn signal line to
another point.
3. Activate the disable switch and verify that the
vehicle equipment detects this action. Also
observe the DISABLE indicator and the
ON/OFF switch indicator. Both indicators will
be flashing green when the disable switch is
activated. See Table 6-1.
4. Verify that Disable mode activation is correct.
If Latching Disable mode is used, the vehicle
control unit stays in Disable mode after the
disable switch is returned to its normal state.
Turning the vehicle control unit off for a few
seconds and then back on removes the
Disable mode.
If Non-Latching Disable mode is used, the
vehicle control unit removes the Disable mode
as soon as the disable switch is returned to its

6.3 Performance Tests
WARNING
A completed installation that is not tested may
result in improper system operation, which may
result in accidents and/or injuries. To avoid
this problem, test the system to verify proper
operation. Improper system operation may
result in unsafe driver action.
These installation instructions are the result of
tests performed in our laboratory and we believe
these tests to be accurate and complete.
However, each installation involves variables
that cannot be controlled or predicted. These
variables may affect the operational
characteristics of the system.
To ensure proper system operation, GTT strongly
recommends that, when the system is turned on,
the installer functionally tests the system using
the following procedure.
1. Place the Opticom GPS-equipped vehicle in
an area with GPS coverage. This is either
outdoors, away from nearby buildings and
overhanging trees, or inside of a garage that
has adequate GPS coverage.
2. Verify that the vehicle equipment acquires
GPS.
Turn the vehicle control unit on by pressing the
ON/OFF switch. The unit should acquire GPS
within a few minutes; however, it may take up
to 15 minutes. A green GPS indicator means
that GPS has been acquired. An amber GPS
indicator means that GPS has not been
acquired. If GPS has not been acquired within
15 minutes, turn the control unit off and wait
another 15 minutes. Then turn it back on. If
the unit still has not acquired GPS, verify that
your location has a good view of the sky. If
you are unable to acquire GPS, contact GTT
Technical Service or your dealer.
3. Verify that the vehicle radio/GPS unit is
transmitting information properly. The
vehicle radio/GPS unit will not operate if the
system has not acquired GPS. Therefore,
this check cannot be completed unless you
have GPS.
Place the vehicle to be tested in close
proximity of another known good Opticom
GPS-equipped vehicle or intersection. This
vehicle or intersection also must have good
GPS coverage.
Vehicle Equipment Installation Instructions
24
If a vehicle is used, its radio must be placed
in Transmit mode because vehicle radios will
not transmit unless they hear an intersection
radio. Open the View Inputs Sensing
window and select the Transmit Test tab.
Press the Test Mode button. The vehicle
radio will now transmit even if it does not
hear an intersection radio. The vehicle radio
will stay in this mode until the next power
cycle.
Note: If an intersection is used for this
test, activate the vehicle’s disable switch
or you will be placing priority requests to
the intersection controller. Therefore, it
is recommended that another Opticom
GPS-equipped vehicle be used for
testing.
Open the Vehicles & Intersections Heard
window under the Real Time Activity section
in ITS Explorer. This window is duplicated in
both the Vehicle and Intersection modules of
ITS Explorer. Verify that you are receiving the
correct following parameters from the vehicle
under test.
Agency ID
Class ID
Vehicle ID
Priority
You should also receive the following
information from the vehicle under test. You
will not be able to verify the values, but you
need to verify that the information is being
transmitted. Examples:
Latitude and Longitude
Heading and Velocity
Fix Type
Position Dilution
Horizontal Dilution
Satellites
Activate the left turn signal, the right turn
signal, the disable switch and verify that the
correct information is being transmitted. This
verifies that the vehicle under test is set up
correctly and is transmitting all required
information.
4. Verify that the vehicle radio/GPS unit is
receiving information properly.
Connect the computer running ITS Explorer to
the vehicle under test and repeat the above
procedure looking for the data being
transmitted from your known good vehicle or
intersection equipment. This verifies that the
vehicle under test is receiving all required
information.
