Hi, i'm new in this.
i just bought a china breakout board (Mach3 engraving machine cnc 5 axis stepper motor driver interface board with optocoupler isolation C2B4).
the problem is its din't come with user manual.
I do contact the seller but no feed back.

Can some one help me for the wiring, especially with the connections of the LPT cable wire connections.
Are the male & female pin connect to parallel or have to wire jumping?

I have so many questions to ask but for now i ask 1 first.

Please help. Thanks.
