3.3V cPCI in NI PXI 1042 with NI PXI 8105

[lapenta]

I have just purchased an NI-PXI-1042 with a NI-PXI-8105 controller. I have just now realized that the Chassis is keyed for 5V logic. The cPCI card that I purchased the NI system to support is keyed and setup for 3.3V logic. What is the best solution to configuring the NI-PXI-1042 and NI-PXI-8105 to support my 3.3V cPCI card?

Thank you,

Hello Jason,

I found this KnowledgeBase article that discusses the 3.3V and 5V logic levels for cPCI. National Instrument chassis are keyed, and only offer 5V logic levels. Unfortunately, this means that cPCI cards that support only 3.3V are not compatible with NI chassis'.

In this case, if a 5V or universal version of your cPCI card is available, that would be the best way to go.
