ViStatus = niHSDIO_ConfigureDataInterpretation ( ViSession vi, ViConstString channelList, ViInt32 dataInterpretation);
Purpose
Selects between high/low data or valid/invalid data interpretation during a static or dynamic acquisition operation.
Select NIHSDIO_VAL_HIGH_OR_LOW to get logic high or logic low values. Select NIHSDIO_VAL_VALID_OR_INVALID to determine if the signal is within the specified voltage range (above NIHSDIO_ATTR_DATA_VOLTAGE_LOW_LEVEL but below NIHSDIO_ATTR_DATA_VOLTAGE_HIGH_LEVEL) or outside the range (below NIHSDIO_ATTR_DATA_VOLTAGE_LOW_LEVEL or above NIHSDIO_ATTR_DATA_VOLTAGE_HIGH_LEVEL).
 |
Note NI 654x/656x devices only support the high/low mode of data interpretation. NI-HSDIO returns an error if you select valid/invalid mode for an acquisition with these devices. |

Parameters
| Input | ||
| Name | Type | Description |
| vi | ViSession | Identifies your instrument session. vi was obtained from the niHSDIO_InitAcquisitionSession or niHSDIO_InitGenerationSession function. |
| Channel List | ViConstString | Identifies channels to apply settings. Use "" or VI_NULL to specify all channels. |
| Data Interpretation | ViInt32 | Selects the data interpretation mode. Defined Values NIHSDIO_VAL_HIGH_OR_LOW (3)—Data read represents logical values (logic high or low level) NIHSDIO_VAL_VALID_OR_INVALID (4)—Data read represents whether channel data is within the specified voltage range. |
Return Value

| Status | ViStatus | Reports the status of this operation. To obtain a text description of the status code, call the niHSDIO_error_message function. To obtain additional information concerning the error condition, use the niHSDIO_GetError and niHSDIO_ClearError functions. The general meaning of the status code is as follows:
