keyword=LHRS DAQ problem fixed
The problem turned out to be a bad connection of L1A signal from the
retiming board to the TM module. I unplugged the cable and plugged in
back in at the retiming board and got the gates signals back (checking
from the scope). And the newly started runs have data now. The pins of
the retiming board are kind of loose. If you touch the L1A cable at where
it is connected to the board, sometimes you might loose the gate signals.
