Tim,

This makes a good starting point but doesn't really explain how to
hook up homing switches let's say. EMC uses one pin (pin 12(S5)) for
input of homing. Where is the input coming from on the other side of
the switches? How are the switches wired? Series, parallel, or
series/parallel? It don't say. And I can't find anything that does
say.

The DANCAM drawing shows the homing switches grounding pins 12 and 13
as they close but with pin 11 (N.C. for DeskNC) being inverted I
assume it goes high when the switch is opened for DeskNC?

There is too much confusion here and that is why I'm making the
suggestion for wiring diagrams.
