Thanks for the help. I also looked at the photo (UIM240-pdf). you say your shape exactly. I asked, but, whichever LPT pin. or together to make another circuit.

The pin from parallel port depends on your TYPE of BOB and where you pick up the connection

You still need to tell us which 'Break-out Board (BOB)' you are using WITH your stepper drivers (UIM240). You need a BOB to send the signals to the drives (UIM240).

window_s,
Break-out Board = 25 pin Interface board. What type of board did you use?

Actually, IMHO, any 25pin parallel port BOB will do... You can even run without one...
I recon Window_s has a language problem more then anything else. Give him/her some time...
