I completed the baseline k2 kit but I seem to have some problems: The Voltage measurements from pg17 of the trouble shooting section differs from what I'm seeing in the receive case: U4 5-pin should be 5 but I get 0 U4 7-pin should be 0 but I get 5 U5 1-pin should be 0 but I get 5 U5 2-pin should be 5 but I get 0.
I've traced through - U4, 5-pin is connected to U5-2 and 3 pins on the control board. I've followed the leads and they are clean. I've resistance checked them and everything appears properly connected. I've also checked resistance to ground and U4-5 is not shorted. Likewise U4-7 connets to U5-1 and two chips on the control board. They seem to be digital logic pins, so I wonder if the listed voltage is incorrect? Otherwise it seems one of my chips is bad. Suggestions?
