I am thinking now I may have a bad cable, I have unhooked the one causing problems, and if the other one doesnt cause any problems, I will switch the cables and see if that changes things.
I changed out the order and the the 100/30 is in the far right port, (as you are looking at it) and the 100/50 is in the middle port, and the Smart Shunt is in the far left port.
The 100/20 is connected to the far left USB port.
So far it's working, I think the order was the problem, the 277 is the 100/30, the 278 is the 100/50 and the 288 is the 100/20.
