Re: 7-segment display wiring? HELP?

I wanted to provide an update to this thread.
After many months of delays on my part - I was finally able to get my system up and running in late December. Discovered that the displays were wired up wrong. The wiring schematic on the back of the unit is in the middle of the two sets of pins - confusing, as it overlays two pins on the left, seemingly indicating 'GND' and '12V' and then two on the right, indicating 'SCL' and 'SDA'. I wired according to that, instead of what I should have, being one plug on the right being GND|12V|SCL|SDA and one on the left (jumper) being the same. Doh.
I also discovered, thanks to a suggestion from Ryan at ElectricBrewingSupply, that my probe wires were wrong - I am only using two wires of 3 wire XLR connector, and I used one of the dead pins... DOH!
Once corrected, and my BCS restored from having it's bus fried, it was back to working.
I hope you other gents have gotten yours working as well.
