Trying to fit 2 MPG

[m_c]

I am sorry but I have to disagree as I have a 5V mpg running on one of those boards

You could of maybe mentioned that in your previous post

However, back to basics.
Is the MPG switching the inputs of the BOB (the voltage should switch every two notches of the MPG on each channel)?
Are the inputs shown on the diagnostic screen in Mach?

But does the ESS support MPGs?
I know the original USS had a dedicated MPG input, which they dropped for the ESS. However I've not paid much attention to what Warp9 have or have not added since I last had one several years ago.
