[Halld-pid] [New Logentry] Follow-up Re: Follow-up Re: Follow-up Re: CSS TOF Discriminator Display frozen

[Alexander Somov]

The problem seems to be with the DMA readout of discriminator scalers in 
the TOF crate by a scaler monitoring program. We don't read out DSC crates 
within DAQ. Very likely, there is a problem with a DSC module (s) in this 
crate. Discriminators for other sub-detectors look Ok - they are initialized 
exactly in the same way. One has to check TDC hits in the TOF, I think 
that they should be Ok  (except may be for the bad module, if any).

Somov compared the configuration to that of other working scalers and they are similar.  One suggestion is that there could be a firmware issue with the TOF disc. boards.   We need to track this down.
