If Board Handle was passed:

Channel number in the DIO board, each board has 32 I/O channels. I/O channels number range is 0-31.

Each DIO board has 4 Auxiliary channels. Auxiliary channels number range is 0-3.

If Master Board Handle was passed:

Channel number in the DIO domain, each DIO board adds 32 I/O channels. I/O channels number range is 0-991 (1 master and 30 slaves).

pnInputDataSource

PSHORT

Input data comparator can be as follows:

0  DIO_LOW_THRESHOLD_COMPARATOR: data will be the result of the comparison done on the input data by the low threshold comparator, logic levels are as follows:

Logic Low: whenever the input signal is below the low comparator threshold.

Logic High: whenever the input signal is above the low comparator threshold.

1  DIO_HIGH_THRESHOLD_COMPARATOR: data will be the result of the comparison done on the input data by the high threshold comparator, logic levels are as follows:

Logic Low: whenever the input signal is below the high comparator threshold.

Logic High: whenever the input signal is above the high comparator threshold.

pnStatus

PSHORT

Returned status: 0 on success, negative number on failure.
