DAQ

• ODB /eq/cb02/settings:
• dl_ctrl for A+B 0xC0FE
• dl_ctrl for A*B 0xC0F0
• A is grand-OR of all scintillators on the TDC-A cable (enabled by dl_trg_mask[7..0], 8 bits for the 8 scintillators)
• B is grand-OR of all scintillators on the TDC-B cable (enabled by dl_trg_mask[15..8], 8 bits for the 8 scintillators)
• each scintillator signal (A[7..0] and B[7..0]) is L*R hardwired in dl/dl.sv
• dl_tdc_mask can be used to disable each of the 32 TDC inputs (see map between TDC inputs and scintillator channels)
• there is no button to disable chronobox counters and rates for individual CB channels
