Greetings and I hope you all have a Great 2024!

James, Steve, All - Thank you for all your efforts to date on the Hermes Lite project - A fantastic radio system that inspired me to get licensed.

I am trying to wire up the XB125B to the IO board and am struggling with identifying the j6 and J4 pinout numbering - Is there a page like this one for the HL2 that shows a picture of the jumper pinouts for the IO Board?  Apologies if it has already been discussed, I missed it and recent searches by me came up blank.

I did.  They do not show the jumper pin #s on the board itself.  I am unfamiliar with the standard for pin orgering-number.

If you look at the DB1 pictures on the HL2 page IO · softerhardware/Hermes-Lite2 Wiki (github.com)  you can see an example of standard pin number assignments, they are in dark lettering over each pin pad.  The square pad is pin 1.  Odd pins down 1 side, even down the other.

Dan, I think you got it figured out, but in case any other member has the same question here's a screenshot of the PCB Diagram with the corresponding numbers on J4, J6, J8 and DB9:
