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-836x: PCI Express MXI-Express board
• NI PXI-8360: PXI MXI-Express module
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.
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 1 m, 3 m, and 7 m copper cables.
