How to run the DAQ in EEL building room 108.
Three VXS crates each with 15 FADCs. So, that is 720 channels of FADC.

Start/stop runs
Usually the DAQ is already running one of the workspaces on cdaql3 (giant screen). Then it's like any other CODA system. Stop/start runs with the Run Control GUI (rcgui).
How to CODA start from scratch.
On hccoda@cdaql3, type "startCoda" (note the capital C). The xterms with components pops up. Those are the 3 crates nps-vme1, nps-vme2, nps-vme3, as well as the event builder PEB1. The Run Control GUI (rcgui) pops up. We normally want the configuration "NPS_3crate" for the aforementioned crates. We also have single-VME configs ("vme1", "vme2", "vme3") but they only work if the trigger is plugged into the master TI. More on trigger below.
- FADC parameters are defined in the usual config file
ssh -X nps-vme1 -l hccoda c cd cfg and see nps-vmeN.cfg where N = 1, 2, 3 Please don't modify these unless you know what you are doing.
Trigger
Curently (Jan 24, 2023) the trigger is a front-panel trigger going into the 7th input of the TI-master. This input is labelled "TS#1". Later we'll have a fancy VTP trigger and I'll update this. But currently the trigger consists of the "and" between a scintillator on top and bottom of the calorimeter. And each scintillator is the "or" of the two PMTs that are connected to the two ends of the scintillator.
