The NI 1428 specification does not say what versions of the PCI spec it is compatible with. NI 1428 specifies 5 V and +/- 12 V supplies but from what I know versions 2.3 and 3.0 of the PCI spec require 3.3 V power supply compatibility. What PCI version is the NI 1428 and does it properly support 3.3 V supply voltage?

Hello Image_maker,
Most of current NI PCI devices support both 5V and 3.3V PCI/PCI-X standards. You can tell the difference by looking at the keying on the device. For PCI-1428, it has universal PCI which would support both 5V and 3.3V standards. You can refer the the knowledgebase article below for reference.
Will a National Instruments PCI Board Work in a PCI-X Bus?
