  The Expert DAQ panel is opened from Settings->Expert DAQ. The MAC address and IP address that are shown in the panel should correspond to the ethernet port on the DAQ PC. These addresses can be set in the JRichEcConfigurator through the Settings->PC network... panel, and should not need to be changed once the system is configured.

During beamtests, the number of MEP events per ethernet packet was increased to reduce the network packet loss. The settings used were Fragmentation size (hex)=1000 and MEP events (dec)=33.

During beamtests, the number of MEP events per ethernet packet was increased to reduce the network packet loss. The optimal setting is probably the maximum number of events that will fit in a single Ethernet fragment. In this firmware the fragment buffer is around 1kb so up to about 30 events per MEP is optimal.
 

DB pulser

The settings for the internal pulser on the digital boards are controlled via the Settings->DB pulser... panel. The textfield Pulse count sets the total number of pulses generated on the DB. The Pulse delay is in units of DB clock ticks. Generally, for setups using the trigger board to distribute triggers, it is better to use the trigger board to generate pulser triggers rather than the internal DB pulser.

Threshold/DAC scan

Threshold/Testpulse(DAC) scan

 
Changed:
<
<
Threshold/DAC scans can be launched from the Settings->Threshold/DAC scan panel, which asks for the number of events per threshold setting, as well as the range of thresholds and increment size (which can be negative). The threshold or DAC scan is started from the corresponding Threshold scan or DAC scan button. To record the scan, the Recording checkbox in the JRichEcControl panel should be ticked, but the Start and Stop buttons on the JRichEcControl panel should not be used to control the scan.

It is not necessary to click Stop in the Threshold/DAC scan panel when the scan is finished unless the scan gets stuck. In this case, Stop may be needed to clean up before you can continue with a new scan or other new run.

In case the scan gets stuck, use Interrupt to clean up before you can continue with a new scan or other new run.
 

CLARO or MAROC?

JRichEcConfigurator allows you to manage settings for both CLARO-based or MAROC-based systems. How these are used depends on the run control program. Typically you can ignore the settings for the MAROC if you are working with the standard CLARO-based EC.
