Data Voltage Custom Levels

This instance of niHSDIO Configure Voltage configures the voltage levels of the data channels using the specified high and low levels. Refer to the device documentation for possible voltage restrictions.

Note  If you are using an NI 6541/6542 device for generation sessions, you must set high level to the appropriate logic family value, and you must set low level to 0. For acquisition sessions with the NI 6541/6542, select the same value for high level and low level from the following list: 0.9 V, 1.25 V, or 1.65 V.
Note  If you are using an NI 6544/6545/6547/6548 device for generation sessions, you must set low level to 0. For acquisition sessions with the NI 6544/6545/6547/6548, you must select the same value for high level and low level.

When you use this VI, NI-HSDIO coerces the values you specify according to the voltage levels supported by your device. Refer to your device specifications for more information about the supported voltage levels. After you commit the session, you can read the Data High or Data Low properties to get the actual value of the configured custom levels.
