Short Name: DataVoltageRange

Property of niHSDIO

Specifies the voltage range used for all voltages on the selected channel. If you are using both acquisition and generation sessions in your application, when you set a voltage range in a session, NI-HSDIO reserves that voltage range for that particular channel after the session is committed. The other session must then set the same voltage range for that particular channel to avoid a reservation conflict error after the initial session is committed.

After you commit both sessions, you cannot change the value of this property until you either reboot the hardware or call the niHSDIO Reset Device VI.

This property is valid for generation and acquisition sessions.

Note  Only NI 6555/6556 devices support this property.
Note   When the Attribute Committal Strategy property is configured to Immediately upon set (Voltage), setting this property while the session is in the Committed or Running state causes the new value to take effect by the time the property returns.

You can select the following PFI channels and clocks for the active channel input of the property node using these strings: PFI1, PFI2, STROBE, and DDC_CLKOUT. These strings are not case sensitive and can be grouped with the standard input strings separated by commas. The following are examples of valid string syntax: 0, 4, 6, PFI1, 7 or 0-12, STROBE, DDC_CLKOUT.
