- Mounting the Toll Antenna in an Overhead Location
- Caution
- To install the toll antenna
- 1. Place the toll antenna below the mounting pipe and insert a U-bolt around the pole and down through the bracket on the side of the antenna closest to the center of the lane. This antenna should be mounted toward the driver side of the traffic lane...
- 2. Rotate the antenna up and toward oncoming traffic. Rotate up 15° from horizontal for a lane. Use an inclinometer or angle finder to check the angle.
- 3. Tighten nuts with a torque wrench to 50 ft-lb (68 N-m).
- 4. Slide the shrink tubing over the coaxial cable, but do not heat it.
- 5. Connect the coaxial cable to the antenna and to the appropriate connector on the Orion Reader. Leave the shrink tubing loose until you have finished configuring the lane.
- Starting the Orion Reader
- To start the Orion Reader
- 1. Connect coaxial cable from toll antenna to ANT 1 port on Orion Reader for a single antenna configuration. Antenna ports 2-4 may also be used for systems requiring multiple antennas.
- 2. Connect host PC or lane controller to Orion Reader using the Ethernet TCP communications port (see Table 3-5.)
- 3. If using Sync to operate multiple lanes with Orion Reader, connect Sync cable to pins 3 and 4 of the Power, Sync, and I/O Connector on the Orion Reader.
- 4. Connect other options as required. See Appendix D, “Orion Reader Options” for detailed installation and operation information.
- 5. Connect the Orion Reader to 19V to 30V DC or 19V to 27V AC RMS @47-63 Hz power supply. See Figure 3-2 and Figure 3-3 for recommended wiring directions.

- Required Supplies
- Guidelines
- To mark the read zone
- 1. Turn on continuous RF power using the #6411 command.
- 2. Secure the test tag to the end of the yardstick using electrical tape or hook-and- loop material. Be sure the tag polarization (horizontal or vertical alignment) matches that of the toll antenna.
- 3. Stand directly in front of and about 5 feet (1.5 m) away from the overhead toll antenna. Hold the stick so that the tag is positioned at a height and angle consistent with a tag installed on a vehicle. The audible tester sounds upon tag read. If t...
- 4. Mark the spot with chalk or tape.
- 5. Move to the left until the sound stops and mark the ground with chalk or tape at the location of the tag when the sound stopped.
- 6. Return to the center and then move to the right until the sound stops and mark the ground with chalk or tape at the location of the tag when the sound stopped.
- 7. Return to the center and step backward 2 feet (0.6 m) and repeat steps 5 through 7.
- 8. Continue moving the tag in this manner, placing marks on the ground to identify the boundary of the read zone each time the sound stops. Continue moving the tag to various locations until the read zone is fully marked.
- 9. You can now connect the outer marks to draw the outer boundary of the read zone.
- 10. Standing at the farthest point of the pattern, walk toward the toll antenna and listen for a continuous sound from the audible tester. If the sound is not continuous, it could indicate a weak or patchy RF pattern.
