8 3 Vehicle Equipment Installation Instructions 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.
Vehicle Equipment Installation Instructions 3.2 Vehicle Equipment 3M™ Opticom™ GPS Priority Control 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, diagnostics, and downloading log information.
10 4 Vehicle Equipment Installation Instructions Features Opticom GPS system vehicle equipment has the following features: ?? Vehicle identification encoding; selectable at installation ?? User-selectable Disable mode; Latching or Non-Latching modes ?? Diagnostic indicators ?? Millions of vehicle identification codes ?? Agency ID capability ?? Wide operational temperature range: –30°F to +165°F (–34°C to +74°C) ?? Meets FCC part 15 Class A specifications ?? 15 & 20-foot cables for installation flexibility
Vehicle Equipment Installation Instructions 5 Installation This section describes the installation of 3M™ Opticom™ GPS Priority Control System vehicle equipment. Please read and fully understand the following paragraphs before starting the installation. ?? Before cutting or drilling any openings in the vehicle or lightbar, draw a diagram showing placement, measurements, and dimensions. Use the diagram to avoid drilling or cutting holes in undesirable locations.
12 Vehicle Equipment Installation Instructions 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. Determine an appropriate location in a protected area inside of the vehicle or trunk. 4. Using the provided screws, attach the Radio/GPS unit to the mounting location. 5. The provided screws are self drilling/tapping screws.
Vehicle Equipment Installation Instructions 5.2 Vehicle Radio/GPS antenna installation 1. Remove the nut and washer from the Radio/GPS antenna. 2. Drill a 5/8 to 3/4-inch hole. See Figure 5-3. 3. Route the cables through the hole. And replace the lock washer and nut. 4. Tighten the nut with a15/16” wrench (a 24 mm wrench may be used if a 15/16’ wrench is not available) 13 5. Apply silicone RTV (not provided) around the antenna if the roof curvature prevents a good seal with the antenna’s built-in gasket.
14 5.3 Vehicle Equipment Installation Instructions Radio/GPS Unit Cable Terminations 1. Route the cables from the radio/GPS antenna through the vehicle to the radio/GPS unit location. 2. Coil up any excess cable. Note: When coiling excess cable do not create any sharp bends in the cable or the cable may be damaged. 3. Connect the cable labeled GPS to the GPS connector on the radio/GPS unit. Connect the other cable to the Radio connector.
Vehicle Equipment Installation Instructions 5.4 Vehicle Control Unit Installation This subsection describes the installation of the 3M™ Opticom™ GPS Priority Control System Vehicle Control Unit. It also describes connecting the radio/GPS cable from the radio/GPS unit to the control unit and connecting the vehicle interface harness to the control unit. Please read and fully understand the following precautionary paragraphs before installing the control unit.
16 Vehicle Equipment Installation Instructions 4. Cut the Radio/GPS cable (black cable) to the 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.
Vehicle Equipment Installation Instructions 17 10. Place the control unit into the mounting bracket. Use the two 1/4-inch acorn nuts and lock washers to secure the control unit to the bracket. See Figure 5-6. The control unit must be level within 15 degrees to allow the internal compass to function. Figure 5-6. Vehicle Control Unit Installation 1. Mounting bracket 3. Acorn nut (2) 2. Lock washer (2) 4. Vehicle control unit 11.
18 Vehicle Equipment Installation Instructions In order for the vehicle equipment to transmit turn signal information to the intersection equipment, it is necessary to connect the interface harness to the vehicle turn signal indicators. 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.
Vehicle Equipment Installation Instructions 6 Checkout 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. This section describes how to check out and test the installed 3M™ Opticom™ GPS Priority Control System. 6.
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.
