Help installing Z axis toolsetter

[adanlicea]

Hello
I've purchased a Chinese Z axis toolsetter, the problem is that instructions are in Chinese and the diagram doesn't even indicate which cables are what. It has 4 cables brown, green, blue and orange, I want to plug it into the CNC board and set it up on Mach3. Anybody has experience this this kind of Z probes? The vendor doesn't even understand English so it's been pointless to ask them for instructions.
I managed to decipher that one cable (don't know the colour) goes to IN2 and another goes to DCM (also don't know which colour)

Much appreciated if someone can help
