Addressing Audio Unit

Addressing the audio unit is crucial for a proper system functioning. Up to 8 audio units can be connected to one splitter. Each audio unit must be addressed to a unique position within the splitter.

Procedure

  1. Pre-configure the jumper on the configuration jumper 12.
  2. The first 4 pins serve for setting the location of the audio unit.
  3. If there is poor access to the pins, it is possible to remove the covers of the electronics.
    1. Slightly loosen the four screws and shift the cover upwards.
    2. Now you can removed the cover.

  4. Set the audio unit position by placing the jumper according to the following table:

    1st position

    2nd position

    3rd position

    4th position

    5th position

    6th position

    7th position

    8th position

  5. If you have removed the cover, put it back in the original position and tighten the screw.
