Error Conditions
The KUSB-3100 module can report an underrun error if the data for
the analog output channels is not sent fast enough from the host
computer. It is up to the host application to handle this error either by
ignoring it or by stopping the output operation.
To avoid this error, try slowing down the output frequency,
increasing the output buffer size, or allocating more output buffers.
Note: If no new data is available to be output by the analog output
channels, the last value that was written to the analog output
channels continues to be output by the analog output channels.
