Installed With: NI-HSDIO

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.

instrument handle identifies your instrument session. instrument handle is obtained from the niHSDIO Init Acquisition Session VI, the niHSDIO Init Generation Session VI, or the niHSDIO Init Ext Cal VI.

channel list specifies which channels to apply settings to.

Leave channel list blank to apply to all channels.

data interpretation specifies the value for data interpretation.

High or Low (3)	The data read represents logical values (logic high or logic low).
Valid or Invalid (4)	The data read represents whether channel data is within a specified voltage range.

error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source identifies where an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI.

error out contains error information. This output provides standard error out functionality.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
