niHSDIO_ConfigureTriggerVoltageCustomLevels
Specific Function
C Function Prototype
ViStatus niHSDIO_ConfigureTriggerVoltageCustomLevels (ViSession vi, ViReal64 lowLevel, ViReal64 highLevel);
Purpose
This function configures the voltage levels of the trigger channels using user-defined high and low levels.
 |
Notes Refer to the device documentation for possible voltage restrictions. |
| If you are using an NI 654x device for generation sessions, you must set highLevel to the appropriate logic family value, and you must set lowLevel to 0. For acquisition sessions with the NI 654x, select the same value for highLevel and lowLevel from the following list: 0.9 V, 1.25 V, or 1.65 V. | |
| NI 656x devices do not support configuring voltage levels. NI-HSDIO returns an error if you use this function when programming those devices. |
