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.
