7i76e configuration not working

Hi,

I have a CNC mill which I am converting to LinuxCNC with a 7i76e. I currently have the card connected to a Raspberry Pi 4 and powered on, but otherwise nothing is connected as far as motors, etc. I was hoping to just look at the signals on an oscilloscope so I can confirm everything works the way I expect.I created a simple XYZ configuration with PnCConf but LinuxCNC will not start up with this configuration. I get the error:

I have configured the tab "7i76-Analog Output" to be "Spindle Output".

The full error report is attached along with my configuration files. Does anyone know what could be causing this error? It seems to detect and connect to the card fine, but then it falls over on this configuration line. I didn't edit the files manually, so I am not sure what I am doing wrong here.

Thanks,
Jeremy

Interestingly, if I remove the 7i76 analog input (ie set it to unused) then everything starts up OK. But I do have an open loop analog spindle driver that I would like to use...

Ah, some searching of the forum with google gave me the answer I was looking for:

Turns out I had moved the VIN/VFIELD jumper to the wrong "left" So the VIN of TB4 was not being powered.
