pin locations

might be a dumb question I have a 7i96s how how do you no where PIN numbers locations. I'm in the pnccofig it says pin # xx  but where is it on the board ?

What pins do you mean?

If you run:

mesaflash --device 7i96s --addr 10.10.10.10 --readhmid

it will print the 7I96S's function (stepgen, pwmgen, encoder, etc)
terminal block pin numbers.

(replace the 10.10.10.10 with 192.168.1.121 if the 7I96S is jumpered that way)
 

  the header pins on the mesa boardIt's a project that was stared a couple years ago that I'm trying to finish and now on my own its PM728v-t everything is working except the spindle that I'm trying to figure out how and where to hook up. pncofig has PIN numbers I'm trying to figure out where the number is physically on the board. attached image is what I'm trying to hook up

Pncconf does not have pin numbers, for things like 7I96S PWM outputs
and SSR outputs (the things that are needed for spindle interfaces)
They are listed by channel number (the channel number matches
the 7I96S manual names and mesaflash listings)

Do you have a more complete spindle interface description?

It looks like the 7I96S analog output will need an external 12V or 10V source
(since unlike a normal VFD it looks like the drive does not supply a 10V source)

I think what I'm trying to translate pncofig to the physical location on the mesa board

That would be the 7I96S manual that lists the terminal block pins for
step/dir, analog out. encoder  and SSR channels.

These are also listed by mesaflash's  readhmid command
 

When i look at the mesa manual the numbers don’t match for example 30-33 in pnccofig where are those on the board it self 

I'm sure its something simple that I'm over looking or not understanding I'm a new at this
thanks for the help

Those are unused resources (for sserial expansion) and not relevant to
configuration (unless you want to repurpose those I/O pins)
