BLD Generation

This section is included for background knowledge on how to configure LCLS2 BLD from an accelerator IOC.

Taking the GMD (PV base  = EM1K0:GMD:HPS) as an example:

Configuration of SuperConducting Soft x-ray BLD:

(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:ENB
EM1K0:GMD:HPS:SCSBR:ENB        Enable
(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:MULT_ADDR
EM1K0:GMD:HPS:SCSBR:MULT_ADDR  239.255.25.2
(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:MULT_PORT
EM1K0:GMD:HPS:SCSBR:MULT_PORT  10148

For SuperConducting Hard x-ray BLD (LCLS2-HE) replace SCS with SCH.

The supporting PVs are described here (BLD PVs).  More detailed IOC setup instructions are found in the README file of the bsaDriver /afs/slac/g/cd/swe/git/repos/package/epics/modules/bsaDriver.git.

BLD Reception

The LCLS2 DAQ release has tools analogous to the LCLS1 DAQ for debugging BLD reception issues.  The application in the LCLS2 DAQ release can be run as
