An example of how to start DAQ for the stand alone BCAL (four north or south crates) with the external pulser connected to the master TI.

  1. Login to gluon49 under hdops
ssh hdops@gluon49
  1. Load the environment
source /gluex/Subsystems/BCAL/setupcoda3
  1. Start DAQ for 4 north or south crates: bcal_N4_start or bcal_S4_start
    terminate all DAQ processes bcal_N4_exit
  2. Choose configuration: Configurations-->Coda Config-->bcal_s4 (or bcal_n4)
  3. Settings in the Run Control (you have to set these variables once if you edit coda configuration with jcedit)
    Set User --> Runtime Variables --> Config File to /gluex/Subsystems/BCAL/bcal_pulser_ti/pulse
    Set User --> Runtime Variables --> List --> %(CODA_ROL) to /gluex/release/0.1/src/rol/bcal_base_ti
  4. FADC250 configuration files are located in /gluex/Subsystems/BCAL/bcal_pulser_ti
  5. Data output: /gluex/Subsystems/BCAL/data/south4
    /gluex/Subsystems/BCAL/data/north4 (default)
  6. Due to some glitches in the firmware you have to start run first before enabling external triggers (will be fixed)
