Monitor Power

When power is provided to the monitor by the vehicle ignition, it initially powers to a standby state, and the power button displays in red. Pressing the power button will turn the monitor to the active “on” state and the power button displays in green. When the ignition is turned off, the monitor saves the current state and resumes the same state when the ignition is turned back on. The monitor will change from the standby state to whichever camera view is selected when a trigger signal is applied to one of the trigger wires.

Monitor Installation

  1. Determine the monitor mounting location and then decide which mount will be used. The U-shaped mounting bracket works well mounting to the dash or ceiling. The adjustable fan mounting bracket works well when adhesive mounted to dashboards or windshields, it also can be screw mounted.
  2. Use the included mounting hardware and install the mounting bracket. If the adhesive mount is to be used, hold the mount against the desired location and check to see if it fits well. If there is a curve to the surface, bend the bracket slightly to match the mounting surface before adhering. Remove the adhesive backing and then firmly press the mount to the surface and hold for 30 seconds. It is recommended to allow the adhesive to cure for 1 hour before attaching the monitor.
  3. Locate your ignition-controlled power supply and ground locations in the vehicle. A fused location is not needed as the power harness for the monitor includes an inline fuse.
  4. Make the proper connections to the red and black wires on the power harness to the vehicle power connection as noted in the diagram below.
  5. Determine if the triggers are going to be used for automatic activation of the monitor. Triggers are not required as the user can manually select cameras, but they are recommended for the rear camera input:
    • Rear Camera – Locate a reverse-activated signal such as the power supply to the backup lamps or backup alarm. Tap into the wire using a suitable wiretap method and then route a wire to the Camera 3 trigger input on the monitor power harness.
    • Driver's Side Camera – Locate a left turn activated signal on the front of the vehicle such as the power supply to the turning lamps in the headlight assembly, or in the fender. Important! Do not use turn signals from the rear taillight assembly as they double as brake lights. Tap into the wire using a suitable wiretap method and then route a wire to the Camera 1 trigger input on the monitor power harness.
    • Passenger Side Camera – Locate a right turn activated signal on the front of the vehicle such as the power supply to the turning lamps in the headlight assembly, or in the fender. Important! Do not use turn signals from the rear taillight assembly as they double as brake lights. Tap into the wire using a suitable wiretap method and then route a wire to the Camera 2 trigger input on the monitor power harness.
  6. Route the power harness large female connector to the mounting location of the monitor.
  7. Mount the monitor to the chosen mount and make the connection from the monitor to the monitor power harness. Make note of the connector alignment arrows making the connection.
  8. For each of the cameras to be installed, connect the PX-1943 10M A/V cable to the camera input of the monitor power harness, then run the male end of the cable to the camera installation location on the vehicle.

Monitor Operation

Monitor Power

When power is provided to the monitor by the vehicle's ignition, it will power on to a standby state showing a red power light. Pressing the power button will turn the monitor to the on state and change the color to green. When the ignition is turned off, the monitor will save its current state and resume it when the ignition is turned back on. The monitor will also change from the standby state to whichever camera view is selected when a trigger signal is applied to one of the trigger wires.
