Please note the following "quirks" currently present in S452 that are important [B]a) Strips/Thresholds[/B] Thresholds are 0xA, 0xA, 0x10 [Maybe changed depending on rate, etc] Some strips are very noisy - damage? [B]b) Powering FEE64s[/B] Due to a misbehaving USB hub(?) or cable only 7 FEE TTYs are monitored aida04 and aida05 can take minutes to start, unsure why. aida05 is monitored on nnrpi1 and hence when aida05 is ready it is safe to assume all 12 are ready Watch the logs as normal [B]c) Slow control & nnrpi2[/B] For the Grafana script to read the DSSD HV, it must be ran in a screen session If nnrpi2 is restarted please run the HV as a screen by Putty SSHing (localhost 22) and running [CODE]screen -S caenhv /dev/ttyACM0[/CODE] if screen was just closed you can do [CODE]screen -x caenhv[/CODE] to reconnect The pulser ideally should be started the same [CODE]screen -S pulser /dev/ttyUSB0[/CODE] To allow remote changing by NH/GSI The pulser is sent to all subsystems for correlation and should be kept on at 2 Hz for the experiment IN the pulser putty you can check the settings by typing [CODE]display settings[/CODE] And general commands: [CODE]help[/CODE] The NIM crate can be monitored /dev/ttyUSB2 but you should be careful It is very easy to turn off the NIM crate if you do I run it in a tmux session with ([CODE]tmux attach -r[/CODE]) to have it "readonly" There is a small script on nnrpi2 [CODE]./check_usbs.sh[/CODE] to see which ttyUSB is which device As they can change if the pi is rebooted [B]d) Scaler Readout[/B] If powercycled FEEs, enable the scaler in Local Controls page by setting BuTiS interface control to 0x3 To enable scaler readout after GOing the run please open the Correlation Control page (Act on all FEE64s) and set control to 0x1 [U]This has to be done every time the FEE64s are set to GOing[/U] [B]e) New Tape Server[/B] For waveform readout in future experiments, the tape server is in "Expert" mode which is harder to use Please read the "How to use" instructions by clicking the button on the bottom right Or in a terminal [CODE]cat /MIDAS/TclHttpd/Html/ETape/1.txt[/CODE] [B]f) GSI/MBS[/B] If GSI team ask to restart AIDA MBS you may need to restart the MBS relay so it can reconnect To start MBS in a terminal [CODE]ssh despec@x86l-94 cd mbsrun/s452/aida_to_mbs mbs @startup [/CODE] It should report it connected to AIDA-3 - if not check the MBS relay is running or restart the relay Please check the MBS rate command [CODE]rate -nst -rst -nev -rev -ndata -rdata -st[/CODE] That the "Streams" column does not frequently (ever) have 0 empty streams If so AIDA data may be getting dropped and should be looked into If another DESPEC DAQ has failed this will eventually happen and is not a problem But if it occurs in normal operation it is concerning Do NOT stop the AIDA run without talking to GSI team - if no AIDA data the whole MBS DAQ stops and blocks all other subsystems. It is best to keep AIDA ticking over constantly and let MBS start/stop files when relevant. Of course if things have to stop it is OK but inform GSI shifters so they can take action Encoding: HTML ELCode plain Suppress Email notification Resubmit as new entry
