H1 ISI BSC1 - Test

Earlier this morning, Dave modified the IOP models at ITMY to reintroduce the WD between SEI and SUS computer. Then, we figured the BS was part of the WD (tripping the ITM). Dave removed the BS from the IOP WD in H1susb123.

Model modifications were also made in h1isiitmy and h1susitmy (IPC channels for the WD). After swapping and plugging few cables, we were finally able to drive the ISI. But due to data errors in the dolphin, the SUS-ISI connection broke frequently (cf error during 2 hours) then tripping the ISI. The reason is still unknown (SUS CPU maxed out?). Also, the WD bit sent by the SUS model should be high when the SUS WD is not tripped and low when SUS WD is tripped (or model/connection is dead/broken). Currently, this is not the case.

I temporary allowed 150 errors per second of transmission error (4K native rate => 36ms) to run some measurements overnight.
