| + | |
| − | | + | |
| − | 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".

| + | |
| − | | + | |
| − | 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!(run 1019)
| + | |
| − | | + | |
| − | 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. (run 1020)
| + | |
| − | | + | |
| − | 5. Added some more delay(~200ns) between trigger and signal, changed PL=100(400ns) and PTW=80(320ns) in the crl code. Now I can see the signal from the decoder in fDecode!! See [http://hallaweb.jlab.org/halog/log/html/1209_archive/120928163904.html halog] (run 1028)
| + | |
| − | | + | |
| − | 6. For now, this is the only working decoder (/adaqfs/halla/adev/fadc/fDecode)... more later.
| + | |
| − | | + | |
| − | '''Date : 1 Oct 2012''' (R. Michaels)
| + | |
| − | | + | |
| − | 1. Got my own version of fDecode to compile and run in ~adev/bob. Spent about an hour figuring out where the heck the
| + | |
| − | slot number comes from (I did). Slot 5 for now.
| + | |
| − | | + | |
| − | 2. Latency 300 nsec. Trigger window 260 nsec. I learned how to adjust this. Runs 1040 - 1045 are ok. I can see the data, and
| + | |
| − | it moves to another channel when I move the input cable, but there are some strange things: (a) For data in chan 15, I see many times a repitition of the same ADC data, it's not physical. Meanwhile for chan 16, the data looks normal (monotonic, looks like a pulse). And (b) When I do run #N the first few events look like run N-1 conditions, as if the ADC is not cleared. Obviously, some work to do here.
| + | |
| − | | + | |
| − | 3. Neither fDecode nor decoder_new compiles on adaq1. Instead must use adaql* (with the "L"). The CODA-related problems for adaq1 were allegedly fixed, so we may try running CODA there again sometime. I'm more interested in the FADC for now, though.
