Installation and Setup: RTMS Echo Sensor
Mounting the Sensor
For a complete height and tilt angle mounting chart see Mounting Height and Tilt Settings.
NOTE: Always follow local wiring codes and local standards that apply to the location in which the RTMS Echo is being installed.
- Attach the bracket to the roadside pole (or another specified location) using stainless steel banding or bolts.
- Secure the RTMS Echo to the mounting bracket using the 9/16" (14 mm) bolt, washer, lock washer, and nut. Make sure that the cable connector is on the bottom of the unit when it is mounted.
- Adjust the RTMS Echo to be perpendicular to the travel lanes and level from side to side.
- Tilt the RTMS Echo so that the top of the senor is aimed at the fartherst monitored zone.
- 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.
6. Connect the cable from power and communications to the Echo sensor.
NOTE: 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.
7. Connect the other end of the cable to power and communications in the breakout box according to the pinouts show below (see Connecting Power/Communications).
NOTE: 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.
8. After all the connections have been made, turn on the mains.
9. Aim the sensor.
