> 15.20 DAQ histogramming & data transfer #1 enabled > Merger configured, started, input paused > Following DAQ GO nnaida9 data transfer 'X' nnaida19 histogramming 'H' disappear - see attachments 1-7 > > Workaround suggested by https://elog.ph.ed.ac.uk/AIDA/230 appear not to work > ########### The reason being that it is not the solution to this problem. When the X will not stay it seems to be because the FEE64 cannot open a connection to the Server. -------- Entry 230 was to help when the rates in the fastest part of the system caused one of the FEE64 to be blocked for control access while waiting for the slowest to produce data. Judging by the next entry in this diary I think this is now understood but .... 'belt and braces' seems a good idea ;-) I've not seen the 'H' disappear but it could similarly mean that the enabling of Histogramming is failing. Perhaps check the Options settings for this FEE64 to see that the Histogram quantity and size parameters are the same as another FEE64. > > 16.25 Resolved data transfer issue > nnaida9 producing SYNCs but merger data queue blocked > rebooted aidas1 > > nnaida19 histogramming issue remains > > 17:50 6 DSSD insalled > > From front to back of stack: > > DSSD 1 = 3131-9 > 2 = 3058-25 (rotated 90deg w.r.t. other detectors - p-strips horizontal and n-strips vertical) > 3 = 2998-23 > 4 = 3058-5 > 5 = 3058-6 > 6 = 3058-7 > > HV mapping (-ve bias): > > DSSD Braid Core > 1 nnaida20 nnaida17 > 2 nnaida19 nnaida18 > 3 nnaida12 nnaida14 > 4 nnaida11 nnaida13 > 5 nnaida4 nnaida6 > 6 nnaida3 nnaida5 > > 18.55 Change ASIC settings > > nnaida18, nnaida21 positive -> negative input > diode link threshold 0xca -> 0xbf > LED settings negative -> positive, threshold 7200 -> 9000 > > nnaida19, nnaida24 negative -> positive input > diode link threshold 0x11 -> 0x23 > LED settings positive -> negative, threshold 9000 -> 7200 > > Saved new settings to DB key 2016May28-18.52.07 > Saved new DB key to Options Encoding: HTML ELCode plain Suppress Email notification
