Wiring 7i96 and THCAD

That did it! We're in business.

Thank you, Peter!

Does it matter at all what the input mode is set to on the index signal, jumper W4?

No, because index is not used ( The index input is a no-op unless the index enable pin is true )

@AgentWD40 What are you using to create your diagrams. I have seen this style used before by others and always wondered if they are hand drawn in a drawing program or if there is some specific software designed to create them.

Thanks

Either ms paint or inkscape, depending on much punishment I want at the time.
