Alright Guys,

I think I am just totally missing something here....

Running2.8 on stretch
Trying to setup 7176e atm but also have 7i85 but dont have a clue where to begin to add that...

I make it to the I/O portion and I am just completely lost.

What are the connectors? Are they related to the actual physical connectors on the board like TB1 TB2 ect?

What are the pin numbers? Are they related to physical Pins on the board?

If the pins are not physical pins is there some ryme or reason to what connectors/pins I should assign my I/O ect. to?

once I assign my step gens and skip to the next page, basically everything is grayed out on the motor/encoder config

Also is something supposed to happen when I click the launch test panel button?

Maybe I am over thinking this but I am just lost.

Sorry for the barrage of ignorant questions but I have spent most of the day googling and reading this forum but I feel more confused then when I started, Though I will say everyone here has been extremely helpful!

For a 7i76e, this is a better guide
forum.linuxcnc.org/27-driver-boards/3191...ection-sheet?start=0

All I've ever done is load up halshow and look for the pins I need. But if you look at the 7i76e manual all of the pins are listed in order and matched against the physical port number

I made up a table listing the physical pin (eg TB6-05), the signal (Input 04) and where its connected (gantry Y min limit)

I feel like i'm completely missing something... How do you determine what physical terminal relates to what pin in PNC Config?

I see the listings in the manual for what signal is at what terminal I just don't understand what the numbering convention in PNC Config is referring to?

I appreciate any info!

pncconf numbering system uses the component number rather then the pin number.
The reason is because different daughter cards can change the pin numbering.

Maybe this map - actually for the 7i76 may help:

So Chris,how would I identify say input 20? I see it is on terminal 5 on TB5 on the board, but How would I identify in in PNC Config?
