Vehicle Equipment Installation Instructions 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-ofway 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. Vehicle Equipment Installation Instructions 3.2 Vehicle Equipment The Opticom™ GPS System vehicle equipment is intended for use on priority vehicles. The vehicle equipment consists of a radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver, a radio/GPS antenna, as well as a control unit, which also provides an interface point between the radio/GPS unit, the vehicle wiring, and an external PC used for configuration and diagnostics. This manual describes how to install the vehicle equipment. Please be aware of the following operational characteristics of this equipment. Appropriate agency ID, vehicle class, and vehicle ID numbers are determined at the time of installation and are programmed by the user via configuration software. The Disable feature uses an additional switch (customer supplied) that connects to battery negative or positive when actuated.

If you see the right (opposite) turn signal sense change from active to inactive or viceversa. 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 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. 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). 7. Verify that the control unit on/off switch is set to the OFF position. 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. 10. Connect the vehicle’s positive battery cable, then connect the negative battery cable. 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. Vehicle Equipment Installation Instructions 21 5.5.3 Low Priority 5.5.4 Probe Priority/GPS always out 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. 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. 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. 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. 22 Vehicle Equipment Installation Instructions 6 Checkout This section describes how to check out and test the installed Opticom™ GPS System. 6.1 Configuration Setup and Checkout Using the Vehicle Configuration window of the ITS Explorer application, configure the vehicle control unit with the following parameters: (See the on-line Help files and the Operation Manual for additional information.) Using the General Configuration window, set the following parameters: Configuration • Vehicle Name Up to 40 alphanumeric characters • Agency ID 1 – 254 • • Vehicle Class 1 – 15 Vehicle ID 1 – 9999 Operating Mode 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 normal state. Table 6-1. Vehicle Control Unit Indicators Indicator Color or Condition Meaning POWER Green Power applied to unit ON/OFF Switch Green Flashing Green Power applied to unit Vehicle in Disable mode DISABLE Off Vehicle NOT in Disable mode Vehicle is transmitting “Probe” mode Vehicle in Disable mode • Disable Mode Latching or Non-Latching Amber • Disable Trigger method +12 VDC to Ground Ground to +12 VDC Flashing Green • GPS Receiver Power Options Always On Standby 6.2 Input Verification 1. Open the Vehicle Configuration window in ITS Explorer. 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 GPS Amber Green RADIO Amber Green Not receiving GPS, radio not transmitting GPS has good 3D fix No communication between radio/GPS unit and vehicle control unit Good communication between radio/GPS unit and vehicle control unit Vehicle Equipment Installation Instructions 6.3 23 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. 24 Vehicle Equipment Installation Instructions 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.

Inspect the components at regular intervals to ensure proper system operation. GTT recommends the following: • Each intersection system and vehicle system should be inspected and tested at least every 12 months to ensure it functions to your specifications and requirements. • Intersection systems should be tested with known good vehicle systems. • Vehicle systems should be tested with known good intersection systems. • You should develop a test plan that fits your department’s operations and meets the needs of your system. • You should keep accurate and up-to-date records of system performance and test results. Note: When washing the vehicle, avoid pointing a high-pressure washer at the radio/GPS antenna. 26 Vehicle Equipment Installation Instructions Vehicle Connections and Configurations 9 GPS Output Function The Opticom™ GPS system utilizes information from the constellation of GPS satellites. This data may also be used by other devices that are installed in an Opticom GPS equipped vehicle This section provides details on the format of the GPS data as well as details on how to connect to the Opticom GPS equipped vehicle to obtain this data. Caution Notes The Global Positioning System (GPS) is operated by the United States government, which is solely responsible for its accuracy and maintenance. The system is subject to changes which could affect the accuracy and performance of all GPS equipment. Although the Opticom GPS system uses a precise GPS receiver, any navigation system can be misused or misinterpreted and therefore become unsafe. It is the user’s responsibility to use this position information prudently. This information is intended to be used only as a navigational aid and must not be used for any purpose requiring precise measurement of direction, distance, location or topography. Use this product at your own risk. To reduce the risk, carefully compare indications from the GPS to all available navigation sources including the information from any other NAVAIDS, visual sightings, maps etc. For safety, always resolve any discrepancies before continuing navigation. This section describes the necessary connections and configuration to obtain the available GPS data from Opticom GPS vehicle equipment. Connections 1. Connect the White/Orange (GPS TXD -) wire of the Vehicle interface harness to pin 2 on a DB-9 or DB25 connector. 2.
