Entry number 346206

For synchronization purposes, I connected copies of the fast clock 
103.5 kHz to the scalers in the BigBite FB crates.  ROC 8 and 9 have 
LeCroy 1151 modules, whereas ROC 10 has an SIS3800.  For all crates, the 
fast clock is connected to the first scaler channel (1).  The LeCroy 
modules require a gate to count, so I took a NIM-bar output to create the
gate for them.  

In the crl code, we just need to make sure that the scaler code is enabled 
and reading out the correct channel.  At the start of run, the scalers
are cleared.

I would like to add a scaler to ROC 5 to add a copy there as well.

I had a problem with the fast clock double-pulsing, which appears to be 
related to a bad level translator output.
