niHSDIO Configure Voltage

Configures the voltage levels for the data, trigger, and event channels. You can use either predefined logic families or custom voltage levels.

For more information on the voltage options available with your device, refer to Voltage Levels and Logic Families.

Note  NI 656x devices do not support configuring voltage levels. NI-HSDIO returns an error if you use this VI when programming those devices.

This instance of niHSDIO Configure Voltage configures the voltage levels for the data channels using a logic family. Refer to the device documentation for descriptions of logic families and possible voltage restrictions.

	instrument handle identifies your instrument session. instrument handle was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI.
	logic family identifies the settings for the instrument generation and acquisition operations. You can choose 5.0 V, 3.3 V, 2.5 V, or 1.8 V Logic for the logic family.
	channel list identifies which channels to apply settings. Leave channel list blank to apply to all channels.
	error in describes error conditions that occur before this VI or function runs. 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 was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. 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.
