28 Operations
Table 3-6: Card Number Configuration Settings
Default card number is 15.
3.7.2 SSI_TRIG
As an output, the SSI_TRIG signal reflects the trigger event signal
in an acquisition sequence. As an input, the PCIe-9814 accepts
the SSI_TRIG signal to be the trigger event source. The signal is
configured in the rising edge-detection mode.
3.8 SDI
In some applications, marks may need to be added to some data.
The PCIe-9814 uses SDI to accomplish this. The lowest 3 LSBs
correspond to the logic level of SDI2 to SDI0.
