All (10) B737 gauges can be controlled by a single Mini Maestro 12- Channel USB placed in the OVH panel. This setup however would require very long extensions for the Brake Press and Flaps servos. Other option is to use 2 separate controllers: 6 ch in the MIP and 12 ch in the OVH. Not utilized ports can be used as digital inputs/outputs.
Backlight can also be powered from the controller ports through the included splitter cable.
Open Cockpit controller users:
OC servo card requires pinout change per page 4 of the manual. DO NOT change pinout at the servo plug if the backlight is powered through the included servo splitter ! Change pinout at the main servo splitter plug only.
