Nice.
One thing to keep in mind when wiring Mesa and other boards, inputs and outputs start from 0, so input 1 on connector is input 0 in hal, and so on.

You are right.
I was something i knew earlier because i ones had this problem already, but please look at this picture from grabcad of the 7i76E on bottom (The inputs seem to be wrong, but when counting from the input 16 from TB6 and continue terminal TB5 to pin 22 then it seems to be the correct inputs)

Because of that picture i choosed Input 21 and 22. I am now a bit angry about my self, because i thought about it to change in the .hal to input 20 and 21 before i wrote the thread, but i dont know why i have not done it.. I could save your and my time, because that was the only reason why the switch/settings did not work properly.


EDIT: i edited the picture and marked the correct Pin names for the .HAL. This might help others in future so that they not get confused by the original picture which was not edited.

Sorry, now it is there.
I have edited the picture in Photoshop so thats it clear. The original picture is from Grabcad, here the link: grabcad.com/library/mesa-7i76e-7i76e-1

EDIT: i just thought about it if the reason for the wrong input pin numbers is because i have it in Serial mode 2 ?
In the standard mode the Pins 21 and 22 might be correct as on the grabcad picture.

Are you aware that you can restrict these switches to les positions by seting a pin in the wholes on the front.

Thanks Mike for that Information. As soon as I will be back home I will test it. I just checked the picture from the aliexpress product page and I see 2 holes on the front. I will let you know when if it's possible to restrict the switch to 4 positions
