If you have a GSI account it should be possible to connect to aida-gsi remotely via the following
SSH into lx-pool.gsi.de with GSI Linux username/password (ssh username@lx-pool.gsi.de)
Then SSH into aida-gsi via ssh npg@aida-3

Two raspberry pis:

nnrpi1 - FEE64 system consoles
nnrpi2 - AC Mains Relay & CAEN HV

Startup:

1. Plug in micro-USB on pis
2. Connect via ssh: ssh pi@nnrpi1  or ssh pi@nnrpi2
3. Start MIDAS:
cd /MIDAS/TclHttpd/Linux-arm
./TclHttpd-server

4. Connect from aida-gsi web browser
http://nnrpi2:8015 - For AC Relay Control
http://nnrpi1:8015 - For Pi Monitoring (Get list of USB terminals, Connect)
-> Parse USB log for details to check if all FEEs have finished booting completely or not

5. For CAEN HV connect via ssh/X (ssh -X pi@nnrpi2) and run
putty &
Opens putty window to connect to the CAEN HV module (Serial /dev/ttyACM0)

11.50: DAQ stopped, TapeServer stopped
       
       TapeServer restarted, DAQ restarted

       Writing to file TapeData/NULL/R9_0 with Clock ReSync at start.

       Wasn't writing to disk, restarting (DAQ stop, TapeServer stop, TapeServer start TO DISK, DAQ Start)

       Writing to file TapeData/NULL/R10_0

12.04: DAQ stopped, TapeServer stopped, merger stopped
       FEE64 power relay switched off
       Raspberry PIs switched off and disconnected
       water cooler stopped
       Mains IEC cables removed from relay

       
        

AIDA@DESPEC MACB time switch settings before and after WR are as follows.

Attachment 1 - MACB 1-4 from left to right

MACB number:                           1        2        3        4

100MHZ clock setting (before WR):      0        2        2        2

White Rabbit setting (after WR):       3        3        3        3

Attachment 1 - summary analysis R2_0

               increased slow comparator & LEC/MEC fast comparators cf. R1_0 to minimise random noise

Attachment 2 - summary analysis R3_0

               per R2_0 but BNC PB-5 pulser frequency increased from c. 2Hz to c. 1kHz
               pulser to *all* channels 12x FEE64s

Attachment 3 - summary analysis R4_0

               open TapeSever file, DAQ GO, Start ASIC Readout (*correct* DAQ start sequence)

Observations

- some RESUME but *zero* PAUSE data items observed

- information types 4 & 5 not equal for R2_0 and almost, but not quite, equal for R3_0 & R4_0 

- information types 4 & 5 start data file with 'correct' DAQ start sequence

           

Analysis of file GSIJan19/R1_0 (white rabbit data)

attachment 1 - overall statistics

attachment 2 - verbose output listing all data around first six identified timewarps

attachment 3 - analyser.f (old version for 48 bit timestamp)

attachment 4 - analyser.f (new version for 64 bit WR timestamp)

Observations

1) File does not commence with information type 4 & 5 data items

   DAQ/TapeServer start sequence issue??

2) DAQ RESUMEs observed for all FEE64s - DAQ PAUSEs *not* observed

3) Number of information type 4 & 5 data items for each FEE64 *not* the same

4) reported idle & elapsed times incorrect - presumably analyser.f bug

 

1) Click on item "Merger MK2" in top panel
   This kills any existing Merger existence and loads a new copy.

2) Start (if needed) browser conection to localhost:8115.

3) Click on "NewMerger Control"

4) In NewMerger Control, click "Reload"

5) If MergerState = IDLE, click "SETUP".

6) Wait until state = STOPed

7) If links shown are correct, click "GO"

8) Wait until popup about "Resume Merger" appears and click OK

9) when writing to disk, click "Forward Output to Data"
