Mounting the Sensor

For a complete height and tilt angle mounting chart see Mounting Height and Tilt Settings.

  1. Attach the bracket to the roadside pole (or another specified location) using stainless steel banding or bolts.
  2. This is a picture of the software.
  3. Secure the RTMS Echo to the mounting bracket using the 9/16" (14mm) bolt, washer, lock washer and nut. Make sure that the cable connector is on the bottom of the unit when it is mounted.
  4. Adjust the RTMS Echo to be perpendicular to the travel lanes and level from side to side.
  5. Tilt the RTMS Echo so that the top of the sensor is aimed at the farthest monitored zone.
  6. Secure the position by hand tightening the nuts. Once the aiming process has been completed the nuts can then be securely tightened.

    Make sure the mains are turned off prior to connecting wires from the Echo cable to the breakout box.

  8. Connect the cable for power and communications to the Echo sensor.
    • If using a 12 volt power supply it is recommended that the cable length from the power supply to the Echo sensor be no more than 50 ft (15.24m) in length.
  9. Connect the other end of the cable to power and communications in the breakout box according to the pinouts shown below (see Connecting Power/Communications). This is a picture of the software.
    • In addition to connections shown above, the non-colored wire in the cable must be connected to Earth ground in the breakout box if the cable is not terminated with an RJ-45 connector. If it is terminated with an RJ-45 connector, the connector must have an element to which the ground wire can be connected.
  10. After all connections have been made, turn the mains back on.
  11. Aim the sensor.
