Re: [CAD_CAM_EDM_DRO] Wiring Problems

Hi Tim, Chris

If you were running EMC, the is a usefull IO exerciser utility with a GUI
built in. Just click on the relavent "pin" to alter it's state, and check the
output has actually changed.

If you are running in a MS envionment, unless there is a utility somewhere, a
small BASIC program should suffice - I would have thought there is a program
out there writen for Windows. A Google search may well turn something up.

Regards, Paul.
