**debugging old half, 6 channels have issues - TDC or discriminator issues maybe for 4 of them - 2 might  be related to VME slot ? -
 
−
look with Bryan's decoder located in /site/coda/contrib/devel/dataDecode - if really looks like hardware issue can use VME bus analyzer
 
−
** Ben setup the FADC gui  - will be useful for FADC/detector debugging - Scott will write some documentation on wiki
 
−
** start cabling other half of detector maybe next week
 
−
**control pulser - use L1A to trigger LED, or use a VME pulser ( will try to give a DVCS LED board to Juan Carlos )
 
−
*Grinch
 
−
** DAQ issues - crashing for long runs
 
−
** need to investigate - maybe check event size

**need new TS crate to check the final timing
 
−
** takes about to generate Shower trigger : 60 ns cable + 60 ns logic + cable 25 m = 100 ns  ~ 250 ns
