Following the h1isiham5 model change last friday to correct the BIO card assignments, Jim W reported continuing binary output switching problems with h1isiham5.

We have found the problem.

The drawing D1000298 shows the following:

The IO Chassis has two BIO cards installed. Each card has an input and output connector, each connector pig tails to two cables (lower 32 channels and upper 32 channels). 

The CER rack has two binary input chassis installed (one for ham4 and one for ham5) and only one binary output chassis shared between the two chambers (ham4 uses lower 32 channels, ham5 uses upper 32 channels).

So the inputs are straight forward, CARD0 both cables go to the back of ham4 binary input chassis, CARD1 both cables go to the back of the ham5 binary input chassis.

The problem is with the binary outputs. The drawing shows that CARD0 lower 32 cable goes to the lower 32 of the binary output chassis and the upper 32 cable is not used. With CARD1, lower 32 cable goes to the upper 32 of the binary output chassis and the upper 32 cable is also not used.

We found that CARD1 binary output is missing its cable, and both cables from CARD0's output go to the output chassis. In other words ham4 gets two cables and ham5 gets none. The fix is to run a fourth cable to the CARD1 output, and use its lower32 for the output chassis upper 32 connector.

The h1isiham5 model is in agreement with the drawing, so no software change is needed.
