Controlling a PXI/SCXI Combination Chassis With a PXI Multifunction Card

Issue Details

I would like to control a PXI/SCXI Combination Chassis with a PXI M Series device. Which device can be used and what do I need to pay attention to?

Solution

If the PXI M Series DAQ card has a standard full backplane connector on the back of the card, it can control the SCXI side of a PXI/SCXI Combination Chassis. Most current M series cards are only shipped with hybrid Connector and cannot be used to control the SCXI portion of a PXI/SCXI Combination Chassis. There are still some cards that are sold with the standard PXI connector option so that they can control the SCXI portion of a PXI/SCXI combination Chassis:

• PXI-6221 (P/N: 779113-01)
• PXI-6229 (P/N: 779115-01)
• PXI-6251 (P/N: 779117-01)
• PXI-6259 (P/N: 779119-01)
• PXI-6289 (P/N: 779123-01)

On the product page for each of these devices, two part numbers are given. One part number is for a version that will work in both a PXI Express and PXI Chassis. The other part number is for a version that can control SCXI in a PXI/SCXI Combination Chassis (the part numbers listed above). Both versions are clearly marked on the product page.

All other PXI M Series, like the PXI-6220, are only sold with the hybrid connector and cannot be used to control SCXI in a PXI/SCXI Combination Chassis.


A PXI Card with a Standard Connector - Can be Used to Control SCXI


A PXI Card with a Hybrid Connector - Cannot be Used to Control SCXI


A PXIe Card with an Express Connector - Cannot be Used to Control SCXI

Additional Information

PXI M Series with the hybrid connector began shipping on 2/28/2006, so boards received before this time will be able to control SCXI in a Combination Chassis. If there are doubts as to which version you have, the hybrid connector has a gap in it, while the version that can control SCXI does not, and has a full backplane connector.
