Setting Movement of claw machine gantry

[Begenk]

Hi, I'm newbie...I have involve with claw machine for 2 year now. I recently purchased a second hand claw machine that work just fine. The mainboard of the claw machine as attach.  The previous owner only know some code setting...so i've mess around a bit with the code setting but I don't quite find code setting for speed  motor/gantry for the claw machine. I have try to look for this type of mainboard and only find mainboard with the same type in blue colour with code setting for speed motor/gantry available. If  anyone could or would be willing to guide on this mainboard setting?
