The HRS DAQ is used for Optics, for measuring Qsq, and background studies. This is expert driven.
We will need a checklist for switching between counting mode and integrating mode. The old checklist is linked below. We'll need instructions which are at least as good:

L-HRS DAQ runs on adaq3 ........ R-HRS DAQ runs on adaq2
Account: adaq
CODA will normally be running already. But, to start CODA from scratch on either HRS: "startcoda"
The running config is usually LeftHRS or Righthrs, but there may be other configs for special purposes.
Triggers are (still to be defined)
T1: S0 scintillator T2: S3 scintillator (behind Quartz) T3, T4, etc.
How to set Prescale factors: Type "prescaleL" or "prescaleR" and use the obvious GUI.
Scalers display (xscaler): Login to aonl1 as the a-onl account and type "xscaler", then do what it says to do. Note that xscaler is normally running on the hapc3 computer above the adaq1 console.
Triggers for PREX T1 = S0A & S0B T2 = S3 T3 = S0A || S0B T4 = Upstream Quartz T5 = Downstream Quartz T6 = ((S0A & S0B) & S3) = T1.and.T2 T8 = Clock (1024 Hz) Note about prescale factors Max prescale factors: ps1-4=16777215; ps5-8=65535 T9-12 cannot be prescaled but any trigger can be turned off with ps=0
