Information on the Relevé Motor Driver PCB



The motors inside of the Relevé Spot fixture are driven by Motor Driver Boards.
There are a total of three of them in the fixture located in the following positions:

  1. Yoke
  2. Optics Module
  3. Effects Module

Because these cards are similar in all three locations, their ID must be set to tell the card which location it is in, and thus can perform the correct functions.

Near each driver card, there is a key which shows which ID to set, if a terminator jump is installed, and where to land the wires on the card.



Because the Effects Module is the last card in the data chain, it must have a termination jumper installed on J15
