Jim and Dave.

After seeing some confusing trend data about what the default RMS-trip level and time-to-kill times are (should be 110mV and 20mins respectively), we went to EY and performed the following tests:

pre-test: put SUS, ISI and HEPI into safe states, no DAC drives anywhere. The IOP SWWDs for SUS and SEI were panic'ed.

1. powered down the HWWD, verified 3 ISI Coil drivers were powered down.

2. powerd up the HWWD, noted it would not boot until we pressed the front panel reset button.

3. read the HWWD settings via BIO connection to h1susetmy model's hwwd part, settings of 110mV and 20min confirmed

4. restarted the h1susetmy model, noted that the hwwd part in the model seems to program the HWWD without being asked to

5. unplugged the control BIO cable from the back of the HWWD (retaining the monitor BIO cable), restarted the h1susetmy model. Its hwwd programming part froze with lack of acknowledgements, but the LED monitoring continued to work

Lastly we plugged everything back in, un-panic'ed the IOP SWWDs, damped/aligned SUS, damped/isolated SEI.
