Common Questions

This appendix lists common questions related to the use of the 
MXI-Express controllers.

General Hardware

What are the board names of the MXI-Express remote controllers? 

•

NI PCIe-8361/8362: PCI Express MXI-Express interface

•

NI PXIe-8360: PXI Express MXI-Express interface

How many PXI bus segments can I connect together with 
MXI-Express? 

The PCI specification allows up to 255 bus segments. MXI-Express does 
not limit this number, but the maximum number of bus segments allowed 
can be BIOS or operating system dependent. Also, a computer may already 
have several PCI bus segments internally, and the MXI-Express link also 
has multiple PCI buses internally. Every PCI Express device has at least 
1 bus segment, though it will have more if it includes a bridge or switch.

What host PCs are compatible with MXI-Express for PXI Express?

Refer to KnowledgeBase 3U7CI4D8 at 

ni.com

.

Note

Due to the point-to-point nature of PCI Express, MXI-Express supports only the star 

configuration. You must use traditional MXI for the daisy chain configuration.

General Cabling

What is the maximum length of a MXI-Express copper cable?

The maximum length for a MXI-Express copper cable is 7 m. National 
Instruments offers 3 m and 7 m copper cables.
