Configure Data Interpretation

Selects between acquiring high/low data or valid/invalid data during a static or dynamic acquisition operation.

Note PXI/PXIe-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).

Inputs/Outputs

datatype_icon

session in

Instrument session obtained from the Initialize Acquisition Sessionnode, the Initialize Generation Sessionnode, or the Initialize External Calibrationnode.

datatype_icon

channel list

The channels you want to apply settings to. Leave channel list blank to apply to all channels.

datatype_icon

data interpretation

The specified value for data interpretation.

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

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Default value: No error

datatype_icon

session out

Handle that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Sessionnode or the Initialize Generation Sessionnode.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
