Shoshana, Jim, Arnaud
The x6 HAM3 new CPS boards have been set to the following configuration (as per E2200455):
- Chassis ungrounded from PCB (P3 jumper removed) - To avoid ground loops (see p33 of the user manual)
- All boards set to slave (P26,27,28 jumpers removed) - This is because the LHO CPS are linked to an external timing chassis and don't need a master board (as per Jim)
- Phase set to 0 (P2 jumper on) - This setting is because the targets are now independant from each other (see point #1 in page 27 of the user manual)
| board SN | probe SN | Location | |
| H1 | 29536 | 22777 | Slot 1 in crate +Y side |
| V1 | 38690 | 22781 | Slot 2 in crate +Y side |
| H3 | 12563 | 22779 | Slot 3 in crate +Y side |
| V3 | 38494 | 22775 | Slot 4 in crate +Y side |
| H2 | 23370 | 22778 | Slot 1 in crate -Y side |
| V2 | 11950 | 22780 | Slot 2 in crate -Y side |
There was some glitching noticed on the channels that were in range prior to this work, which was fixed after this setting change (see attached). Two of the cards were set to Master before and Jim is confident this would have created problems.
Left to do :
1- Label the cards at the front of the boards with module SN and corner #
2- Disconnect the grounding to the chamber of the crate on the +Y side
3- Label the in-air lemo cables with H1, V1, H2 ...
4- Update ICS with the new boards SN
5- Gather the cards that were removed from WHAM3 to send back to microsense for recalibration with a new set of sensors (RMA)
