The DIO domain control signals are using the PXI Trigger Bus lines to distribute those signals.
When using internal clock and strobe only two PXI Trigger Bus lines have to be assigned for the Run and Arm control signals.
Additional lines will be required to be assigned for the external clock and/or external strobe.
The assigned lines will be saved to the INI file to be automatically loaded and applied whenever the DIO is initialized.
By default the DIO will use PXI Trigger Bus lines 0 and 1 for the Run and Arm signals.
Note: The same PXI Trigger Bus line will be used by all DIO boards (Master and Slaves) in the domain.
The following example assigns the PXI Trigger Bus line 0 to the RUN signal:
SHORT nStatus;
DioSetupControlToPxiTriggerBusLineMode(nMasterHandle, DIO_TRIGGER_BUS_RUN_CTRL, DIO_PXI_TRIGGER_BUS_LINE0, TRUE, &nStatus);
