Some eventcodes defined by ACR are described on Carolina's page (see column labelled "new trigger bit"):  Control Sequence Bit (note .  Note that our "eventcode" is their (sequenceEngine#<<16 | sequencerBit#).

• 288 bits of "event codes":
  • some have well-defined meanings (in progress)
  • 16 highest bits are hutch specific for sequences (272-287)
  • DAQ readout groups are "extra bits" included at end of timing frame
• timing frames have "destinations": e.g. bykiks, and bykikh both go to "bsy" dump
• unlike LCLS1 we will not be using event-codes to understand when bykiks has fired: use destinations instead
• To trigger on "every shot" with beam (the equivalent of LCLS1's eventcode 140) use "Mode=FixedRate:1MHz, Destination=Include:DumpSXR" (without the "destination" field I believe you will just get a pure 1MHz trigger)
