- Checked S-band system, data sync problems
Probably due to software opposed to hardware phase stability. Need to always make sure reference is last
channel in card. Also need to check data order.
- Data order (80, 64, 65, 66, 67, 68, 69, 70, 71)
- BPM order (REF5, SF1FF, QF1FF, SD0FF, QD0FF)
Need to rearrange BPM cables

Probably need to make S-band system trigger earlier, so always will be first.
The above order would make BPM (SF1FFx) index 64 the first data element.
To do
- Rearrange cables into SIS cards (as table above)
- Change EDM to reflect changes
- Modify code for BPM 64 to be first in readout system
- Move S-Band trigger earlier
