Power Supply and Ignition Key

Connect Omnicomm OKO video terminals as per diagrams without a ground disconnect switch: without ground disconnect switch after the ground disconnect switch: after ground disconnect switch

Do not connect the terminal before the ground disconnect switch.


Omnicomm terminal shall be installed inside the vehicle cabin or in specially equipped electrics boxes on the vehicle protected from atmospheric precipitation.

Drill 4 mounting holes Ø5.5 mm.

Mounting dimensions

Install the video terminal and fix with self-tapping screws.


Choose the installation site of antennas based on the antenna cable length.

Antennas should be installed inside the vehicle cabin on a flat surface.

Distance from antennas to any metal surface (except for the installation surface) should be not less than 50 mm.

We recommend installing antennas on the windshield or on the horizontal surface of the instrument panel in a place providing a good radio pick-up range of the sky.

  1. Degrease the installation site surface
  2. Remove protective film from the double adhesive tape on the surface of antenna
  3. Attach the antenna with the adhesive side to the installation site
  4. Fix the antenna while the adhesive is setting
