MCC let me take controlled access to investigate the DAQ.
I found that the L1A to L-arm was double pulsing. I traced
this to a NIM/ECL on the floor which was being used as a fanout.
It is usually a bad risk to use a NIM/ECL as a fanout. I changed
this so that only one channel was involved and it cleaned up
the double pulsing.
So, the DAQ should work fine for cosmics checkout.
Unfortunately, the L-arm retiming is quite marginal. Easy to fix, but
a bad sign. I will need to do a thorough shakedown of timing on Monday.
However, it is probably good enough for detector checkout.
Another problem I had was that "rcServer" wouldn't start.
It reported "Cannot open broadcast Handler". Once I fixed it
be restarting msqld, but the 2nd time it happened I decided
to reboot adaql2.
I started a cosmics run 2444. Feel free to start/stop runs.
