AMMRL: BSMS keypad problems.

Hello Folks,

Last week we changed our CPU board and LCB board (in BSMS panel) on our 
AVII 400 system due to communication errors.  The good news is that after 
changing both boards we've re-established communication with the BSMS and 
are happily collecting NMR data once again (usually in automation).  The 
bad news is if we don't run in automation, e.g., shim manually, we observe 
very large changes in the lock display and digital readout on BSMS keypad 
just by turning the knob on the BSMS keypad ever so slightly and only on 
certain shims (Z2, Z3).   It's as if we are in coarse mode, but obviously 
we are not since other shims work fine (Z1 and Z4).  After changing the 
boards, with the help of Bruker Center we selected the correct BOSS 
configuration and checked the board updates in the BSMS utilities program. 
 To make matters worse, we are reluctant to change back the boards since 
one of our systems was just de-energized to make room for a new system. 

Has anyone encountered this problematic behavior with the keypad?.  We 
swapped out the BSMS keypad from another system, but unfortunately that 
didn't work.  When using the "setsh" command everything seems to be 
working fine.  Any advice would be greatly appreciated.  Hopefully in a 
few weeks, we will be up and running on the new system and can restart 
troubleshooting this issue again.
