Jenne, Jeff, Robert, Nutsinee, Dave:

Jenne added the CBRS system to the h1ngn model. This system requires four DAC channels. Robert has given up four PEM channels for this temporary test system.

All models on h1oaf0 were restarted. It was necessary to restart the IOP model when DAC channels are moved between models in order to rescan the channel allocations. Because this in turn requires a restart of h1tcscs, Nutsinee tested disconnecting the temperature control cable at the mezanine chiller to see if we could avoid the chiller trips normally related to h1tcscs restarts.

The restart procedure was:

Nutsinee disconnects temp control cable at TCS chiller

All models were shutdown

h1iopoaf0 started

h1pemcs, h1oaf and h1ngn models started (these models use the 18bit DAC)

h1tcscs, h1odcmaster, h1calcs, h1susprocpi models started

Nutsinee reconnects the temp control cable

The chiller did not trip, this was a successful procedure.

The 8 channel 18bit DAC allocation is:

h1ngn (cbrs) chans 0-3

h1pemcs chans 4-6

h1oaf chan 7
