  43   16 Jul 2019 03:53 Marco RescignoRoutineGeneralrun 774, scintillation events triggering on all 24 channels and 200 us window

Majority of 8, threshold at 1000 ADC count, 24 channels enabled (16 trigger signals)  10 Hz, 200 us window, trigger at 9.5 microseconds.

10 k events recorded.

By direct inspection pileup seems at the 10 % level in the 200 us window.

Trigger setup with a threshold of 1500 ADC count wrt to baseline, on just two channels.

This is also to limit the trigger to 50 Hz, since the busy still did not work.

  31   11 Jul 2019 15:52 ThomasRoutineTriggerinvert first chronobox busy signal
The DAQ seems to be ready for tests with proto-0 tomorrow.  

I had to invert the first busy input in order to get chronobox to produce triggers.  I modified the setup script

setup_chronobox.sh

so this is now the default.  Not sure why necessary.

Another interesting fact; it seems the chronobox only asks for a DHCP IP when it first boots.  I think that
chronobox and ds-proto-daq were rebooted at the same time; ds-proto-daq dhcp server was probably not running
when chronobox asked for IP.  chronobox got IP fine when it was power cycled.
