Common Questions
This appendix lists common questions related to the use of the
MXI-Express Gen II x8 controllers.
General Hardware
What connectors do the NI MXI-Express x8 copper cables use?
The NI MXI-Express x8 copper cables use Molex x8 PCIe connectors. For
more information about these connectors visit Molex at
www.molex.com
and search for
x8 PCIe iPass
.
How many PXI bus segments can I connect together with MXI-Express
Gen II x8?
The PCI specification allows up to 255 bus segments. MXI-Express Gen II
x8 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
Gen II x8 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.
