Short Name: ActiveLoad.CommVoltage

Property of niHSDIO

Specifies the voltage threshold that causes the driver to switch from sourcing to sinking current. If the incoming voltage is greater than or equal to the commutating voltage level, the device sinks current. Conversely, if the incoming voltage is less than the commutating voltage level, the device sources current.

Valid values range from -2 V to 7 V.

The default value is 0 V.

The units are volts (V).

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.

Note  Only NI 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.
