Setpoints
You enable setpoints with the SETPOINT_ENABLE flag. This flag must be OR'ed with the ChanTypeArray
argument values. You set the setpoint criteria with cbDaqSetSetpoints()/DaqSetSetpoints(). The number
of channels set with the SETPOINT_ENABLE flag must match the number of setpoints set by the SetpointCount
argument (cbDaqSetSetpoints()/DaqSetSetpoints()).
Output non-streamed data to a DAC output channel
With NONSTREAMEDIO mode, you can output non-streamed data to a specific DAC output channel. The
aggregate size of the data output buffer must be less than or equal to the size of the internal data output FIFO
in the device. The FIFO holds 524288 samples. This allows the data output buffer to be loaded into the
device's internal output FIFO. Once the sample updates are transferred or downloaded to the device, the
device is responsible for outputting the data. You can't change the output buffer once the output begins.
Trigger DAC output operations with the ADC clock
Specify the ADCCLOCKTRIG option to trigger a data output operation upon the start of the ADC clock.
DIO PortNum
For cbDOutScan()/DOutScan() and cbDaqOutScan()/DaqOutScan(), FIRSTPORTA and FIRSTPORTB are
treated as one 16-bit port. These functions can only be used with FIRSTPORTA. You must configure both
FIRSTPORTA and FIRSTPORTB for output using cbDConfigPort()/DConfigPort().
Quadrature encoder operations
To configure a counter channel as a multi-axis quadrature encoder, use the cbCConfigScan()/CConfigScan()
Mode argument values to set a specified counter to encoder mode, set the encoder measurement mode to X1,
X2, or X4, and then set the count to be latched either by the internal "start of scan" signal (default) or by the
signal on the mapped counter.
You can optionally perform the following operations:
 Enable gating, so that the counter is enabled when the mapped channel to gate the counter is high. When
the mapped channel is low, the counter is disabled but holds the count value.
 Enable "latch on Z" to latch counter outputs using the Encoder Z mapped signal.
 Enable "clear on Z" so that the counter is cleared on the rising edge of the mapped (Z) counter. By
default, clear on Z" is disabled, and the counter is not cleared.
