Logic Families
The NI 656x PFI 3 channel can be independently set to one of two modes: LVDS or single-ended. The actual voltage levels defined by these logic families are defined in the NI 656x specifications. The PFI terminal configuration is software-selectable using NI-HSDIO.
Refer to Voltage Ranges and Settings (NI 656x) for more information about the logic families supported by the other PFI channels.
