 TO-DO list for Parity DAQ
   updated Jan 4, 2019

Cameron & Bob: 1, 2, 4, 5, 6, 11, 12, 13
Tao & Cameron: 8, 9
Bob: 3, 6, 10
Cip, Cameron, Tao: 13  
1 Timing: mostly understood, still small mysteries (LNE)
2 Synchronization-check system. w/help from Ed Jastrzembski
3 File naming, reset run num, finalize configs (INJ, CH, ALL) 
4 Fix scalers on spectrometer crates.
5 clean up cabling, labels, fasteners.
6 Clean up CRL -- eliminate so-called "dirty trick"
7 Check the 7200 scaler setup at injector, find a spare 7200.
8 Pedestal studies, aka cross-talk.  
9 Test JAPAN. Need cable map & labels. Possibly maintain "pan" ?
10 Green Monster maintenance.
11 Test spares.  Repair bad modules.
12 Document everything.  Circuit diagrams, cable map, "how to".
13 Online software, a bit undefined since software is changing.
    (a) automatic production of run-dependent database
    (b) alarms like end-of-run voice (Bob)
    (c) feedback
    (d) coil-pulsing aka modulation aka dithering (Victoria)
    (e) panguin (GUI showing real-time plots)
    (f) prompt analysis
    (g) e-logbook entries 
    (h) archiving EPICs data
Accomplished
 * Revive all crates.
 * Deploy all ADCs needed and test each channel.
 * Build various DAQ configs with subsets of the DAQ crates.
 * Timing diagram, check timing of external signals and readout.
 * ET system upgrade, test rate limits, ensure deadtime zero.
 * Implement Bank structure.
