Even though the serial/power cable tested fine, when it was connected to the power supply, no voltage was present at the T2-301. I tried to measure the voltage on the power supply side of the inline fuse I installed and no voltage was there. However, the voltage at the power supply Anderson terminals had 12.8V. Replacing the Anderson contacts on the serial/power cable solved the problem.
Back in August when I made up this cable along with others, I was having a problem with the Anderson contacts binding in the crimper even after replacing the crimp die. The contacts I replaced looked like they may have been some of those that got bound up. Anyway, I programmed the on board T2 and tested the unit and it works just fine. Now to go and finish the A-I-O setup...maybe next weekend.
