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.
