To power the LPR Processing Unit, you must connect it to the vehicle’s power. The LPR Processing Unit requires a constant power source of 12 VDC protected with a 15A fuse.

Before you begin

  • Have your 15A fuse ready (ATO/ATC in-line).
IMPORTANT:
  • These instructions do not replace your vehicle’s owner manual. If you are unsure about your vehicle’s internal wiring, see your owner manual before continuing.
  • Solder your connections and protect them with heat shrink tubing.

What you should know

  • The system requires an ignition signal to turn on and off the LPR Processing Unit gracefully. Simply shutting off the main power to the LPR Processing Unit can corrupt the LPR Processing Unit and make the system inoperable.
  • The LPR Processing Unit can be used to switch power for auxiliary devices, such as power for the laptop, a modem, and wheel imaging cameras.

Procedure

  1. Connect the wire from the LPR Processing Unit’s (+) terminal, through the 15A in-line fuse, to the vehicle’s 12V power source (permanent +12V).
    NOTE:
    • Install the fuse at the source of your vehicle’s 12V system tapping point. The LPR Processing Unit is already protected internally by an electronic circuit breaker.
    • If you are connecting the primary power lead from the battery, it must be fused within 2 inches of the battery.
  2. Label the primary wire at the fuse to help identify the circuit for future service.
  3. Run the wire to the LPR Processing Unit location.
    IMPORTANT: Protect the wire with a convolute wire loom and secure the loom from potential damage from heat or abrasion.
  4. Connect the wire from your LPR Processing Unit’s GND pole to your vehicle’s chassis for grounding.
    NOTE: Ensure that the ground connection is clean and secure and that there is no paint impeding the connection. Ground connections should also be located away from weld points. Use ring terminals with incorporated, internal locking teeth at all grounding screw locations. This ensures a positive ground connection. For a reliable connection, select ring terminals that are compatible with the size of the stud, screw or bolt that will be used to attach them to the vehicle.
