Is my PXI Card Hybrid Slot Compatible (PXIe-Ready)?
Hardware: Counter/Timers (TIO)>>Devices>>PXI-6608
Problem: I am interested in purchasing a PXI Express (PXIe) Chassis. How can I tell if PXI cards I have already purchased or am planning to purchase will work in the PXIe chassis?
Solution: PXI Express Chassis, depending on the model number, will come with a combination of four types of slots: a PXI Express System Timing slot, PXI Express peripheral slots, PXI peripheral slots, and PXI Express Hybrid peripheral slots.
- PXI Express System Timing Slots accept both PXI Express cards and PXI Express System Timing cards.
- PXI Express slots will only accept PXI Express cards since they are missing the lower connector that Hybrid cards need.
- PXI peripheral slots will accept PXI cards of the standard connector types- those that work in current non-express PXI chassis.
- PXIe Hybrid slots, due to the hybrid or combination of backplane connectors, accept PXI Express cards, 32-bit CompactPCI cards, and Hybrid Compatible PXI cards (also known as PXI Express-ready or PXIe-ready).
NOTE: Pay close attention when selecting a PXIe chassis. Some PXIe chassis, like the PXIe-1075, have no PXI peripheral slots and therefore will not accept the standard PXI cards.
Figure 1: Here we can see an illustration of the four backplane connector types and how they correspond to the PXIe-1075 Chassis Example.
A great way to tell what cards will work in an express chassis is to go to the Online Product Advisor site:
ni.com/advisor. This is an online utility that helps you configure a system. You can select
PXI Advisor»Start Building Your System. Here, you can click the
Chassis tab and select the PXI Express Chassis you are interested in purchasing. Now, when you go to the
Modules tab, you will notice that the incompatible cards are grayed out. For instance, if you select the PXIe-1075 chassis, all the Counter/Timer cards are then grayed out and unselectable due to the fact that they need PXI peripheral slots, of which the PXIe-1075 has none. However, you can add something like the PXIe-4496 Dynamic Signal Acquisition card to your system.
Below is an At-A-Glance Guide to tell if your card is PXI Hybrid Slot Compatible.
