Start/stop runs
Usually the DAQ is already running on one of the workspaces on cdaql3 (the 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 the trigger below.
FADC parameters are defined in the usual config file
ssh -X nps-vme1 -l hccoda ; 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 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.
