MXI-Express x1 Series User Manual
Can I use MXI-Express x1 products in place of MXI-4?
Yes. There are products that offer the same PCI slot-to-PXI chassis connectivity as MXI-4 with
a few differences, as shown in Table C-1.

Unlike MXI-4, the MXI-Express-based PXI controller modules are different from the PXI peripheral
modules used to daisy-chain to subsequent chassis.
†
With hybrid slot support, you can connect an expansion chassis to a PXI Express chassis that contains
PXI hybrid slots.
**
Actual throughput performance varies depending on the system setup and composition.
‡
Universal options for copper and fiber-optic MXI-4 products are available upon request.
***
With the copper MXI-Express PXI modules, you can control a PXI chassis from a PCI Express or
ExpressCard slot in your host computer using the PCIe-8361, PCIe-8362, PCIe-8363, or
ExpressCard-8360.
