See Figure 2-2. 8 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-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
?? 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 vehicles 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 equipments 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 connection for monitoring green phases and also provides additional priority control outputs. The auxiliary harness can be used to provide additional connection for monitoring green phases when the auxiliary interface panel is not required.

This is done by connecting the yellow wire to the left turn signal wire and the green wire to the right turn signal wire. 12. 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). 13. 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. 14. Install the fuse rating label on the blue wire near the fuse holder. 15. 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. 3M 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. 16. Install the fuse rating label on the red wire near the fuse holder. 17. 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. 18. Verify that the control unit on/off switch is set to the OFF position. 19. Inspect all connections and verify that the wiring is complete and accurate as described in this installation manual. 20. Install the fuses (2A, 250V) in the fuse holders. 21. Connect the vehicles positive battery cable, then connect the negative battery cable. 5.4.1 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. This action may be observed using the Vehicles Heard section of ITS Explorer. Refer to the GPS Vehicle Configuration section of the 3M Opticom GPS Priority Control System Operation Manual. Vehicle Equipment Installation Instructions 19 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.

Configuration
?? Vehicle Name Up to 40 alphanumeric characters
?? Agency ID 1 254
?? Vehicle Class 1 15
?? Vehicle ID 1 9999 Operating Mode
?? Disable Mode Latching or Non-Latching
?? Disable Trigger method
+12 VDC to Ground Ground to +12 VDC 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. 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. 20 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 vehicles 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.
?? 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. 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, 3M 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 equipped with a GPS re-radiator. 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 or a working re-radiator. If you are unable to acquire GPS, contact 3M 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.

Description This section provides a general description of the 3M Opticom GPS Priority Control System and a detailed description of the vehicle equipment 3.1 Opticom GPS System The 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 module containing a GPS receiver with antenna and a 2.4 GHz transceiver with antenna
= Processing module Intersection Equipment
= Module containing a GPS receiver with antenna and a 2.4 GHz transceiver with antenna
= Phase Selector
= Auxiliary Interface Panel
= Card Rack/Input File 7 The vehicle equipment, is mounted on the priority vehicle. Its GPS receiver receives 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 vehicles turn signal is broadcast using the 2.4 GHz transceiver. The intersection equipment receives this information. The intersection equipment then compares the information being received from the vehicle to the parameters stored in the intersection equipments memory. If the vehicle is heading towards the intersection in a predefined approach corridor and is requesting preemption and has met all other programmed parameters, the corresponding phase selector output is activated. This output is then connected to the traffic controller preemption input. When activated, the controller will then cycle to grant a green light to the requesting vehicle or hold 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 connection for monitoring green phases and also provides turn signal state dependent preemption outputs.

12 Installation 5.1 Radio/GPS Module Installation This subsection describes how to install the 3M Opticom GPS Priority Control System Radio/GPS Module. WARNING Vehicle batteries contain sulfuric acid and may contain explosive gases. Keep sparks, flames, and cigarettes away. Wear eye protection. Disconnect the negative cable first to prevent shorting the positive terminal to the chassis when removing the positive cable. Battery acid may cause skin irritation and eye injury. Explosive gases may cause severe injury or death. 1. Disconnect the battery before beginning the installation. Disconnect the negative battery cable first, then the positive battery cable. 2. Remove interior panels and headliners, as necessary, to provide access for cable routing. 3. Using the Radio/GPS module as a template, mark where you want to drill holes at the mounting location. 4. Drill three 1/2-inch holes at the mounting location. NOTE: The installer may have to fabricate special brackets to mount the Radio/GPS module on some vehicles. 5. Place the three rubber Wellnuts into the holes. 6. Position the module over the Wellnuts and use three 1/4-20 x 1/2 inch screws to secure the module to the vehicle. Use removable loctite to prevent the screws from loosening. 7. Mark the location of the entry hole for the Radio/GPS module cable. Check the hole location both inside and outside of the vehicle. 8. Drill a 1/2-inch hole for the vehicle equipment cable entrance grommet. 9. Tape wrap the end of the vehicle equipment cable to protect the wires and to ease cable routing. 10. Select an appropriate size grommet from those supplied. The grommets are supplied in three sizes to allow for different thicknesses of vehicle sheet metal. 11. Place the grommet on the cable and slide it toward the module. Leave enough cable exposed to reach the module. 12. Route the taped end of the cable from the module mounting location to the control switch module location. 13. Apply lubricant to the grommet, then insert it into the hole in the vehicle body or lightbar.
(Window cleaner works well as a lubricant.) 14. Remove the wire entry cover from the Radio/GPS module. 15. Disassemble the cable grommet and route the cable through the plastic sleeve and the rubber plug. Leave approximately 5 inches of cable inside the cover and tighten the plastic sleeve to secure the cable. 16. Strip approximately 3 inches of the outer jacket. Be careful not to cut the wires inside. 17. Strip 1/4 inch of insulation from each wire. NOTE: It is very important to not strip too much insulation, which may lead to short circuits; or too little insulation, which may prevent the wire from making adequate contact. 18. Place each wire into the appropriate hole in the terminal block and tighten the screw to secure the wire. There is a label on the terminal block corresponding to the color code for each wire. The terminal block may be removed from the module to allow easier connections. 19. Reattach the wire entry cover to the module and tighten the screws. Push any excess cable back inside of the vehicle. Allow some extra cable for strain relief. 20. Dry the grommet and apply a sealant to the cable, grommet, and vehicle to seal the assembly against moisture penetration. (Silicone RTV is a good choice for a sealant.) 21. Finish routing and securing the cable in the vehicle. Use cable ties to secure all wires away from heat sources and moving parts. 22. Remove the tape from the end of the vehicle equipment cable. Installation 5.2 Control Switch Module Installation This subsection describes the installation of the control switch module. It also describes how to connect the vehicle equipment cable from the Radio/GPS module to the control switch module. Please read and fully understand the following precautionary paragraphs before installing the vehicle equipment control switch module. Installations may include a customer-supplied disable switch in addition to the control switch module. The Disable feature turns off radio transmission when the disable switch closes to battery negative or positive. This feature typically uses an existing switch that indicates the presence of conditions deemed appropriate to disable radio transmission. Such conditions include putting the transmission in park, setting the parking brake, or opening the vehicle operators door.
= The control switch module location must be readily accessible and visible to the vehicle operator. 13
= The control switch module must not be in the path of airbag deployment.
= The cable is routed between the Radio/GPS module, the control switch module, the disable switch, the vehicle turn signals, the light bar switch, and the battery.
= Use care when drilling holes to avoid drilling into undesirable locations. 1. Determine the desired location to mount the vehicle equipment control switch module. Mark and drill two 7/32-inch holes, using the vehicle equipment control switch mounting bracket as a template. 2. Insert the two 10-32 x 3/4-inch cap screws through the holes in the mounting bracket and mounting surface. See Figure 5-1. 3. Use the two lock washers and 10-32 nuts to secure the bracket to the vehicle. Figure 5-1. Control Switch Module Mounting Bracket Installation
14 Installation 3. Connect the TBD wire to a 12 VDC power source that provides at least x amps at all times. In order for the GPS receiver to maintain an accurate location, it is necessary to provide 12 VDC to the receiver at all times. Therefore, it is necessary to connect to a constant12 VDC source. 3M recommends that a direct connection to the battery be used. If this is not possible, use a terminal block with a direct connection to the battery. Install the provided x amp fuse and fuse holder. Attach the provided fuse size label. 4. Connect the TBD 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. 5. Connect the TBD wire to a switch that will actuate when the driver reaches the scene and steps out of the vehicle. This could be a door switch, gear select switch, etc. The switch may provide either +12 VDC or a ground. 6. In order for the vehicle equipment to transmit turn signal information to the intersection equipment, it is necessary to interface the vehicle equipment to the vehicle turn signal indicators. This is done by connecting the TBD & TBD wires to the vehicle turn signal wires. 7. Connect the TBD wire to a point that allows remote activation of the vehicle equipment. A point that provides +12 VDC is required. A switch that activates the light bar is the most common point to make this connection. 4. Cut the 3M Opticom GPS Priority Control System cable to the proper length. 5. Remove about 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 adequate contact. 7. Place each wire into the appropriate hole in the terminal block and tighten the screw to secure the wire. There is a label on the terminal block corresponding to the color code for each wire.

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, 3M strongly recommends that, when the system is turned on, the installer functionally tests the system using an Opticom GPS-equipped vehicle and an Opticom GPS-equipped intersection. To test the system, the installer drives the priority vehicle through the intersection to verify that the system is performing in accordance with customer requirements. 16 Installation 6. Maintenance 3M Opticom GPS Priority Control System components are designed for reliable operation. Inspect the components at regular intervals to ensure proper system operation. 3M 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 departments operations and meets the needs of your system.
= You should keep accurate and up-to-date records of system performance and test results.
Important Notice to the Purchaser THE FOLLOWING IS MADE IN LIEU OF ALL WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTY OR CONDITION OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THE REMEDIES SET FORTH HEREIN ARE EXCLUSIVE. 3M will repair or replace any Opticom Priority Control System component found not to meet 3Ms specifications within five (5) years from the date of shipment from 3M. See Summary of Warranty/Maintenance Coverage for details and limitations of the coverage plan. This warranty shall not apply to incandescent lamps (confirmation lights) or to any system component which has been (1) repaired or modified by persons not authorized by 3M; (2) subjected to misuse, neglect or accident; or (3) has been damaged by extreme atmospheric or weather-related conditions. IN NO EVENT SHALL 3M BE LIABLE IN CONTRACT OR IN TORT FOR ANY INJURY, LOSS, OR DAMAGE, WHETHER NON-SPECIFIED DIRECT, INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL, ARISING OUT OF THE USE OR INABILITY TO USE THE OPTICOM SYSTEM OR ANY COMPONENT THEREOF, REGARDLESS OF THE LEGAL THEORY ASSERTED. 3M has designed, developed and tested each Opticom priority control system component as part of a matched component system. 3M makes no warranty whatsoever concerning the reliability or safety of Opticom system components when used with non-Opticom system products. 3M shall not be responsible for any Opticom component which 3M determines has been damaged in whole or in part by its use with a non-Opticom system product. Sale and use of the Opticom priority control system is expressly restricted to authorized agencies of government customers, within their respective jurisdictions. However, because the infrared signal generated by the Opticom system is not exclusive, 3M cannot ensure exclusive activation by the purchaser. Authorized users who desire to use or coordinate use of the Opticom system with that of other jurisdictions must first obtain the prior written approval of each authorized user in the jurisdiction where use is sought.
