Does anyone know the pin out of the pin headers on the vortex 2 cards?

I have read that digital inputs exist on the card, but after hours of searching on google & forums I can’t find which specific pins to use.

I have an SQ2500 board and found a thread that says the digital cd input pins are in the Header on the right side of the board (as opposed to the wave table header), but the post didn’t specify which pins.

It was in an older thread I found so rather than necroposting I figured it was more in line with the rules to make this new post.
