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:
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, and ID information 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.

Vehicle Equipment Installation Instructions
5.3 Turn Signal Sensing Connections
The turn signal sensing inputs operate by detecting the vehicle’s turn signal circuits. The turn
signal sense wires may be connected to a pulsing turn signal circuit or a steady turn signal circuit.
By default the radio/GPS control unit is looking for a pulsing signal on the turn signal circuit. If you
will be connecting to a steady (non-pulsing) turn signal circuit, you will need to use the On-site
software to change the input mode. See the On-site software help file for more details.
Notes:
• 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.
o This will occur if the emergency flashers are on.
o
This may also occur 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.
o
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.
3. Set the desired operation mode and input type using the On-site software.
4. See section 8.2 for details on how to verify proper turn signal sense operation.
5. Rewire any connections that do not work properly.
22
Vehicle Equipment Installation Instructions
5.4 Disable Sense Connection
It is recommended that the disable sense wire be connected. It is important to provide an
automatic method of disabling the vehicle equipment so that emergency vehicle drivers do not
need to remember to shut off the equipment when arriving at the scene. If the disable sense is not
wired and the driver does not manually shut the Opticom™ equipment off, any in range
intersection/s may remain in preemption mode.
On transit vehicles it is recommend that the disable sense be wired to the passenger door to
disable the transit signal priority request while passengers are loading and unloading.
1. Connect the white wire to a switch that actuates when the vehicle reaches the scene.
a. For instance, this could be a door switch, parking brake, air brake, or gear shift.
b. The switch may provide either +10-36 VDC or a ground when actuated.
c. This switch may be an existing vehicle switch or you may install your own.
2. Using the On-site software set the Disable Triggering Mode:
a. Set to “Apply Ground” if the white wire will be grounded when the disable is
activated.
b. Set to “Apply 12 Volts DC” if the white wire will have a voltage applied when the
disable is activated.
i. This voltage may be +10-36 VDC
3. Using the On-site software set the Disable Operating Mode:
a. Set to Latching if you are connecting the disable sense wire to the door of an
emergency vehicle.
b. Set to non-latching if you are connecting the disable sense wire to a brake switch,
gear shift or the door of a transit vehicle.
4. Verify proper operation. See section 8.2 and 8.3 for details.
Notes:
•
See the On-site help file for more details
•
If the white disable sense wire is not to be used, it is recommended that this wire be
connected to Ground.
o
The Disable Triggering Mode should then be set to “Apply 12VDC”.
o
The Disable Operating Mode should then be set to “Non-latching”.

6 Infrared Emitter connections (optional)
Skip this section if you are not connecting an infrared emitter.
The radio/GPS control unit contains a 6-pin terminal strip for connecting an Infrared emitter.
When connected, the emitter will be able to be switched on and off by the radio/GPS control unit.
When the radio/GPS control unit is put into disable mode, any emitter that is connected to it will
also be turned off (disabled). The emitter will not be put into disable mode but rather shut off.
Therefore the LEDs (794-795 emitters) will not flash at the disable flash rate.
Any model Opticom™ emitter may be connected.
These terminals may also be used to control/switch other devices on the vehicle. Anything
connected to these terminals will be switched on and off with the radio/GPS control unit. Contact
GTT technical support for details on what may be controlled/switched with these terminals.
Notes:
•
See the emitter installation instructions for additional mounting and wiring details.
•
Additional power and ground connections must be made via the terminal strip BAT and

7 Configuration and Checkout
This section describes how to configure check out and verify the installed Opticom™ GPS vehicle.
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.
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.
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. Turn on the equipment by depressing the ON/OFF button and/or activating the
lightbar/ignition.
a. The unit should acquire GPS within a few minutes; however, it may take up to 15
minutes. A green RADIO indicator means that GPS has been acquired. An amber
RADIO 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.
b. Also verify GPS reception using the GPS status screen in the Current Activity section of
the On-site software.

7.2 Input Verification
Click on Diagnostics Link in the On-site software to see the discreet inputs section. This screen will
allow you to monitor the state of various discreet inputs. If the discreet inputs are not seen in this
screen, it will be necessary to rewire the inputs so that they are detected. Contact technical service
if you have difficulty.
7.2.1 Turn Signal input verification
1. Set the appropriate Turn Signal operating Mode using the On-site software.
a) Set the appropriate Right and Left Turn Signal Triggering Mode(If needed) using the Onsite software.
2. Activate the left turn signal.
a) Verify that the left turn signal indicator flashes as switches between On and Off.
b) Pump the brakes several times and verify that only the left turn signal indicator flashes
as switches between On and Off.
3. Activate the right turn signal.
a) Verify that the right turn signal indicator flashes as switches between On and Off.
b) Pump the brakes several times and verify that only the right turn signal indicator
flashes as switches between On and Off.
Notes:
•
There may be a delay before the turn signal status will be seen by the On-site software.
•
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.
o
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.
o
Therefore it is recommended that the yellow and green turn signal sense lines be
connected only to the front turn signal wires.
•
If both signals are being detected when only the left or right signal is activated, it will be
necessary to connect the turn signal line to another point.
•
Set the proper input mode and state of the turn signal inputs using the On-site software. See
the On-site help file for more details.

GTT warrants future system operability coverage as described herein. This warranty shall not apply
to any OpticomTM system components which have been (1) repaired or modified by persons not

Sale and use of the Opticom TM System is expressly restricted to authorized agencies of government
customers, within their specific jurisdictions. However, because the signal generated by the

Authorized users who desire to use or coordinate use of the OpticomTM system with that of other
jurisdictions must first obtain the prior written approval of each authorized user in the jurisdiction
where use is sought.
Since the availability of a GPS signal is out of GTT’s control and is required for OpticomTM GPS
system operations, GTT does not warrant against OpticomTM GPS system failures due to the
unavailability of the GPS signal for any reason.
