Currently we can only run the DAQ in a standalone configuration. Eventually, we will connect it to the SBS DAQ.

update: June 7, 2021

Where to run:  adev account on adaq1.  

I. Bringing the DAQ up from scratch.

  1a. Might need to reboot crates, but probably NOT.
  1b. Might want to kcoda, although startcoda does that.

  2. Type "setupxterms", this pops up 4 xterms

    Might be a good idea to do it from adaq2 because kcoda kills xterms.
    Alternatively you can do the commands in #3 by hand in windows.

  3. In each xterm or window, login.  Note, we now use adev !!

     The old TS is not used in the DAQ; however, it houses scalers
     which are read for xscaler and the usual event type 140 insertions.

       VXS crate with FADC .....  ssh -X halladaq8 -l adev
       lower fastbus crate .....  ssh -X lhrsfb1 -l adev
       middle fastbus crate ....  ssh -X src2 -l adev
       uppper fastbus crate ....  ssh -X lhrsfb2 -l adev

    (if you don't know the password, text Bob)

  4. Startcoda by typing "startcoda"

  5. In each window (step 3) type the appropriate "startrocN" command

	   ROC1-hallada8:  ./startroc1
           ROC2-lhrsfb1: ./startroc2
           ROC3-src2: ./startroc3
           ROC4-lhrsfb2 :  ./startroc4

     You should see the ROCs connect in the red gui (platform).

  6. Now in Run Control GUI (aka rcgui)
 
  Control(upper left)-> Connect -> click the tools thingy (Configure).

     Sometimes one component is disconnected or has a problem (red),
     like "configuring" instead of "configured".
     Often a reset ( <| in gui ) does the trick, and download again.
     Otherwise patiently start at 1.  It works eventually.

  Assuming you can see connected ROCs in the rcgui:  

     Next, Download, StartRun.  If you don't know what a button
     means, let the mouse hover over it for a few sec.

     Configs to use.  Note, the last correctly-running config is what
     gets loaded by default.  You have two configs to pick:

      LHRS -- all 4 crates

      LHRS_FADC -- just the FADC, good choice if Fastbus is down and
                   you don't need Fastbus

  ---------------------------------------------------

II. If CODA running somewhere and you just want to start/stop runs.

      Type "rcgui" and start with point 6 above. 

  -----------------------------------------------------

II. Trouble shooting

     Might need to power-cycle the crate if you things like this:

         ./startroc1: line 2: 31770 Segmentation fault 

   Old ROC processes can cause trouble.  Kill them or reboot.
   
ps awx | grep roc
21353 ?        Sl     0:00 coda_roc -type ROC -name ROC3s
21394 ?        Rl    44:36 coda_roc -type ROC -name ROC3
21477 pts/0    R+     0:00 grep roc
[root@src2 ~]# kill -9 21353 21394

     Some other component not working (e.g. PEB error).
     Be patient, go to I.1 above.  

III.  Power cycling can be done remotely.

     ROC1 (formerly ROC31 during PREX) FADC crate
     go to bbvme1.jlab.org   on firefox on a-onl@aonl1

     For the Fastbus, the hall A Tools screen and "Crate resets"
     used to work, but during the shutdown I have had trouble finding it.
