Use this VI to select between acquiring high/low data or valid/invalid data during a static or dynamic acquisition operation.

Note  NI 654x/656x devices support only the high/low mode of data interpretation. NI-HSDIO returns an error if you select valid/invalid mode for an acquisition with these devices.

Select High or Low to get logic high or logic low values. Select Valid or Invalid to determine if the signal is within the specified voltage range (above Data Voltage Low Level but below Data Voltage High Level) or outside the range (below Data Voltage Low Level or above Data Voltage High Level). Refer to Data Interpretation to understand how data is returned to you.
