  • The wirescanner must be receive its triggers through backplane:
    • TPR:<IOC_LOCA>:<IOC_UNIT>:0:TCRB0:OUTPUTCONFIG 0
    • TPR:<IOC_LOCA>:<IOC_UNIT>:0:TCRB1:OUTPUTCONFIG 0
    • TPR:<IOC_LOCA>:<IOC_UNIT>:0:TCRB2:OUTPUTCONFIG 0
    • TPR:<IOC_LOCA>:<IOC_UNIT>:0:TCRB3:OUTPUTCONFIG 0
  • Next the clock source must be set to SC Mode
    • TPR:<IOC_LOCA>:<IOC_UNIT>:0:MODE
  • Items 1 and 2 will automatically get set, when the facility is set in SC mode.  But if there is some database error, we should check on it,
  • It is possible, the Facility mode is set to override, which is used for local testing. Make sure the override mode is un-selected.
    • <IOC>:FACMODE_AUTO 1 (which is global)
  • The MPS PV must be set to the correct state. This is not a PV we touch, but if the wirescanner is being finicky, we may have set the wirescanner node to NC mode, so it ignores the faults.
    • MPLN:BSYH:MP01:7:LC1_MODE 1
    • This PV sets the Wirescanner node to NC mode.
    • How to find the PV name, dbgrep in iocConsole for this MPLN PV
  • The ATCA slot should have AMC cards installed. (Already installed and PVs should be set). But check if something is wrong. This is to make sure the firmwre knows AMC is installed and knows what triggers to use.
    • AMCC:<IOC_LOCA>:<IOC_UNIT>:ADCSelect0
    • AMCC:<IOC_LOCA>:<IOC_UNIT>:ADCSelect1 0
  • For Wirescanner crate to send data, trigger 10 must be enabled and listening to a correctly configured trigger channel( In our case, it is trigger channel 10)
    • Trigger channel 10 must be set to 1MHz (TPR:L1B:MC01:0:CH10_FIXEDRATE  1MHz)
    • Trigger channel 10 SC Dest mode should be set to Dont Care (TPR:L1B:MC01:0:CH10_DESTMODE   Don\'t care)
    • Trigger Channel 10 is enabled (TPR:L1B:MC01:0:CH10_SYS2_TCTL  Enabled)
    • Trigger 10 is enabled ( TPR:L1B:MC01:0:TRG10_SYS2_TCTL Enabled)
    • Trigger 10 is listening to channel 10 (TPR:L1B:MC01:0:TRG10_SOURCE    Channel 10)
    • Trigger 10 has some width (eg 10ns) (TPR:L1B:MC01:0:TRG10_SYS2_TWID 10)
  • Do not play with Trigger 10 TDES or TPR Master Delay as if you play with it, you will momentarily cause timeout errors.
