Projector Lamp Control Board Bypass 5-pin w/ Schematic

This is an OSRAM configured Lamp control board from Boxlight Pro4500DP Projector. It has three opto-couplers (Phot-transistors) like most projector boards. Instead of the 3-pin connector to mainbaord, this one is a 5-pin using UART communication versus Logic Levels. The pinout is at the end of the video. If someone can help me figure out which wires to bridge or which individual wire to short to ground, it would be greatly appreciated!
