T2 Software at IP5

(Situation as of April 2010)

Software

Latest monitor /data/T2/Monitor_developT2 (at vmepcS2B19-07)

Xml input files

vfat_controller xml files in ~nturini/T2/config

Vfat_controller xml schema at http://cmsdoc.cern.ch/cms/cmt/System_aspects/FecControl/binaries/misc/schema.xsd

Contains among other things VFAT lines

• preamp/shaper settings, same for all
• Control0,1,2,3 (control registers)
• Chanreg1-128 (mask/calpulse/trimDAQ channel by channel)
• Lat (latency)
• Vthreshold1,2 (vt1=threshold, vt2=0)
• chipid0,1=vfatID-16bit : low 8bits + high 8 bits

Xml file contains up to 688 VFATs, and in vfat_controller one can make changes to one or all VFATs

• automate to
  • speed up initial value setting
  • cut down error rate

I modified some of MirkoBerretti's scripts, producing methods to change

• vthreshold1 = read from file: (VFAT ID,threshold)
• chanregNNN= (chanregNNN OR 64) if Read from file: (VFAT ID,channel=NNN)
  • OR 64 is calpulse bit
• easily modified too (not implemented now) :
  • OR 32 is maskChannel bit
  • AND 31=last 5 bits are trimDAQ value
  • For reference: If you set nonzero trimDAQ value, check that control3 AND 7=7 (or at least nonzero)

Scripts available here (see attachment) and on lxplus: oljemark@lxplus:~/public/T2scriptsIP5.tgz

PAGE HALF DONE: COME BACK TOMORROW
