Why does the OPTICOM 764 intersection alternate displaying and dropping the left turn arrow when approaching vehicle has left turn signal activated?
- J
  John PopeSep 7, 2025
  If the OPTICOM Recording Equipment intersection alternates displaying and dropping the left turn arrow when an approaching vehicle has its left turn signal activated, the vehicle brake light bulb may be shared with the turn signal indication, or emergency flashers may be active, or the driver may be using turn signals to indicate lane changes. To resolve this, reconnect the vehicle turn signal sense lines to the front turn signal wires, turn off emergency flashers, avoid using turn signals for lane changes, and reprogram the controller or phase selector.

Why won't the GPS acquire on my OPTICOM Recording Equipment (Radio LED is amber)?
- R
  Richard VasquezNov 21, 2025
  If the GPS on your OPTICOM Recording Equipment isn't acquiring a signal (Radio LED is amber), several factors could be the reason. Initial start-up can take up to 15 minutes, so allow it some time. Obstructions may be blocking the Radio/GPS unit's view of the sky, so move the unit or remove any obstructions. Check if the garage GPS repeater is functioning; if not, repair or replace it. RF interference could also be a factor; try turning off the phase selector for 15 minutes and then try again. Inspect the wiring at both ends of the radio/GPS cable and ensure the radio/GPS cable connector (terminal block) is plugged in correctly. If there is still no GPS, check the voltage between the brown (+) and brown/white (–) wires at both ends, it should be approximately 8.3 VDC. In some cases, the Ra...

What to do if the Call LED does not light when vehicle is in an approach for OPTICOM 764?
- O
  ohendersonNov 20, 2025
  If the Call LED does not light when the OPTICOM Recording Equipment vehicle is in an approach, several factors could be at play. The vehicle might be out of range, so use the On-site software to check the ETA and range for all classes, both high and low priority. Alternatively, the vehicle may not be transmitting; verify this by checking the View Vehicles and Intersections Heard window. Other potential issues include an unmapped approach (map it), an incorrectly drawn approach map (redraw it), or an approach map drawn away from the intersection (redraw it towards the intersection). Radio reception could be obstructed, necessitating a relocation of the radio/GPS unit. It's also possible that the vehicle's operating priority is disabled (enable the priority and set the range). In some cases,...

Why do the LEDs continue to cycle through power-up sequence on OPTICOM Recording Equipment?
- S
  susanjoyceSep 18, 2025
  If the LEDs continue to cycle through the power-up sequence on your OPTICOM Recording Equipment, a 24VDC short is likely the cause. Check the detector wiring for a short circuit.

What does it mean when OPTICOM 764 displays 'Intersection Name not Heard'?
- S
  shellynicholsonSep 14, 2025
  If the OPTICOM Recording Equipment displays 'Intersection Name not Heard' instead of the intersection name, it may be because the name hasn't been heard yet. Press the 'Get Intersections Heard' button again. Alternatively, a name may not have been assigned to the intersection, so assign an intersection name.

Why does the Active Greens window show all greens active continuously on my OPTICOM Recording Equipment?
- E
  Eric BakerSep 13, 2025
  If the Active Greens window shows all greens active continuously on your OPTICOM Recording Equipment, the Green Sense AC neutral (AC–) is likely not connected. Connect the green sense common (white wire) to the cabinet common.

What to do if unable to communicate with phase selector on OPTICOM 764 Recording Equipment?
- T
  Tara McdanielSep 12, 2025
  If you are unable to communicate with the phase selector for your OPTICOM Recording Equipment, first check the cable connection at both the phase selector and the computer. If the connection is good, the baud rate may be incorrect. Use The On-site software to change the baud rate under Environment options.

  Michael CookSep 9, 2025
  If times in the log are incorrect for your OPTICOM Recording Equipment, the time localization may not be set or is set incorrectly. Set the correct offset for your area.

What to do if Call LED lights but controller will not respond for OPTICOM 764?
- J
  janet06Aug 25, 2025
  If the Call LED lights but the controller won't respond with the OPTICOM Recording Equipment, first, check that the phase selector outputs are correctly wired to the controller preemption inputs and logic ground. Next, verify that the outputs are configured correctly. If these are correct, the phase selector outputs may have failed; check that the controller does not see a preemption input, and if not, replace the phase selector. Also, ensure that the controller preemption inputs are active (turn them on). Lastly, the controller preemption inputs themselves may have failed, requiring replacement of the controller.
