Doh! The board is too smart for me.
I think I have to get a proper probe for my silly-scope. I got it off eBay and it didn't come with a probe so I'm just using flying leads now.

What do you think the RS232 communication would look like running along with a 2.5V current sensor signal and 0 ohms on the pot? I may try to get the RTD explorer running to see ....
