15/1/99 2 GLT cables wrongly connected, 1&3=TPB0&2.  This was status for data on 10/1/99.
Sun 17/1/99 500 EMT, GLT, EMC
Tue 19/1/99 Readphase was set to FF in latency.fcx. 
Changed to 6.
Wed 21/1/99 Set read delay value to 20. 
 
'Out of order' errors fixed by fixing FCX. Plots from EMT and GLT show a 2-bin shift in phi.
EMC on-data electronics overheated.

Loaded new version of GLT FEX in L1EmtCalOdf. 
Run 755 was corrupted.

777  run0777.mask
26/1/99 
Runs 0823-0841
Close L1As, 'out of sync' and 'out of order'.  Caused by L1A during ReadEvent. run0831.ax 
run0831.mask
@ 0940 TPB26 in slot 5 loaded with AX V9.0.  Boots ok.
@ 1800 replaced AX V8.12

28/1/99 
Runs 0875-0888
run0885.ax 
run0885.mask 
run0888.ax
Used online 2.3.2
@ 1900 Half of endcap was used. First attempt at Frameclash.
@2100 EMC 10/40 not connected. 
Included in next run.
885 EMC, EMT, DCH, DCT, IFR 53k events.
@2330 888 (probably, number overwritted in paper logbook) Scan AX configuration values Time alignment set to 2 = 0x4000
29/1/99 
Runs 0889-0953
run0891.ax 
run0892.ax 
run0930.mask
@0015 889 2M*  GLT event display shows cosmics with EMT alone.
@0030 890 EMC crashed immediately (3k events)
@0045 891 Time alignment = 4 = 0x8000
892 Alignment back to 3=0x6000
@~1700 Changed all AX from ESP 8.12 to ESP 9.1.
30/1/99 
Runs 0954-1013
run0992.mask 
run0995.ax 
run1001.ax
@~0900 EMC ROM problem; EMC out of run 982->, but EMT still in!
@1445 995 -> 997 Junk run Time alignment = 0x8000
998 Time alignment 3=0x6000
@1655 999 Went full (?) 
Whole front barrel lit up!!!
@1512 1001 Using correct libs and run0995.ax, time alignment = 4. 
Next run time align = 3.
31/1/99 
Runs 1014-1096
1/2/99 EMC: All UPC firmware changed and all IOBs modified.
Fri 5/2/99@~1900 First data taken using own trigger (0x4000). Using pulser, went to 95Hz before 'out of order' error.

Runs 1109-1112
18/2/99 
Runs 1114-1120
19/2/99

EMC: Frame offset was being set to 3. Changed to 8 for running tonight.
22/2/99 
Runs 1174-
Frame offset = 8 
Repeat theta mask for single towers; higher statistics.
run1179.mask
1175 Tower3, 22k events 
EMC crate4 [B0] missing, so UPCs going into Theta4.5.6, Phi0-2 could be bad.
1176 Tower4, 33k events 
EMC crate4 [B0] missing, so UPCs going into Theta4.5.6, Phi0-2 could be bad.
1177 Tower2, 5k events
1178 Tower5, 37k events
23/2/99 Test runs to look at weird tower summers.
