I am looking to try to wire a Gecko G320x to the 7i76U. I found this diagram , which I am planning on using to complete the wiring.

Now, in the manual , there is a diagram of the board on page 3 and a list of the pins ordered by DB25 pin on page 4. The layout of the diagram and pins ordered by DB25 is not as helpful as the diagram I alluded to which another user created.

I have another BOB from CNC4PC, the C11G. In its  documentation  on page 18 you can the pins are labeled on the board diagram making it much easier to figure out which pins to use to wire a stepper/servo driver to the board.

@PCW, after some googling, I believe you are the owner of Mesa Electronics. Is that correct?

If so, I'd like to humbly suggest updating your documentation for the 7i76U to include something like the diagram I found on the forum to make it easier for people to figure out the pins for the 7i76U.

It's true that the 7I76U P1 DB25 pins are not relevant to normal
LinuxCNC setup which deals  with things like stepgen numbers.

The picture on page 4 gives the general location of the I/O pins and the individual
connector (TB1 through TB6) tables give the details. I guess it would be possible
to have another drawing with the individual pins labeled.
