ComptonDaqDev

Here are some notes on the Compton DAQ Development.

Maybe should go into a logbook.

Start date Sept 26, 2012

Bob Michaels, Kalyan Allada

Will work on adev account.

Want to use CODA 2.6. Save the old tcshrc file cp .tcshrc tcshrc_22feb2012

VME cpu bbvme1 presently on bbps1 2002

FADC library for VME /adaqfs/halla/adev/fadc/v1.2

crl is /adaqfs/home/adev/fadc/v1.2/fadc_list.crl

Decoding of FADC /adaqfs/halla/adev/fadc/ComptonAnalyzer

Attempts to make CODA 2.6 work on adev

1. Adjusted .tcshrc, adding things at top (comments there).

2. Create coda26 directory. Put $COOL_HOME there.

3. Minor problems. Had to start msqld by hand (/etc/rc.d/rc5.d/S82msqld_s on adaql2). Had to run cedit or dbedit on adaql1, not adaq1, b/c on adaq1 it complains cedit: error while loading shared libraries: libXm.so.3: (adaq1 has libXm.so.4)

4. Minor problems (part II). Needed links on adaq1, else CRLs don't compile. in /usr/local: ln -s /adaqfs/coda/vxworks-linux gcc-vxworks and ln -s /adaqfs/halla/apar/vxworks/5.5/gnu_vxworks gnu-ppc

5. Minor problems (part III). Can't run rcgui on adaq1 b/c missing libXtst.so.6. I guess it's looking in the wrong place since it's here: /usr/lib64/libXtst.so.6. Punt on adaq1. Use adaql1 (with the "l") for now.

6. startcoda on adev was a link to startcoda_2.5. Change this to startcoda_2.6

7. Bootscript on bbvme1 changed from /adaqfs/home/adev/bbite/vxworks/bbvme1_coda25.boot to /adaqfs/home/adev/vxworks/bbvme1_coda26.boot

8. Adjusted hardware address of TIR and FADC in CRL.

9. Started all the DAQ components "by hand" (startcoda not working yet). A working config is $SESSION=Compton, Configuration = Compton2. A seemingly ok data file is /adaql1/data4/AComp_1012.dat.0

10. "startcoda" and "kcoda" are now working on adev account. A working configuration is "Compton2".

to be continued ....

Date : 28th Sept 2012 (K.Allada)

1. As a first step trying to decode fadc data using /adaqfs/halla/adev/fadc/fDecode which prints data on screen.

2. The 'fadc_decode' prints data with any slot and crate number as an argument ...this is not expected.

3. I tried to change some parameters in the crl (such as PTW and PL) and the decoder shows correct changes made to PTW, at least that works!

4. Now I increased the delay of the trig to TI so as to catch the pulse (it wasn't sufficient), but the decoder still see no signal, only pedestal.
