MXI-3 and MXI-4 to MXI-Express Upgrade Questions
What are some of the improvements from MXI-3 and MXI-4 to
MXI-Express?
MXI-Express incorporates the latest technology to include:
Support for PCI Express slots.
Improved error correction and handling for noisy or harsh
environments.
Improved mechanical connectivity.
Improved performance.
Support for two chassis from a single card in the host PC.
Lower cost.
Can a MXI-3, MXI-4, and MXI-Express board be used together
directly?
No. MXI-3, MXI-4, and MXI-Express boards use different cable
connectors and cannot be connected together. Additionally, the
board-to-board communication protocols differ.
Can I use a MXI-3, MXI-4, and MXI-Express kit in the same
multichassis PXI system?
Yes. Different MXI kits can be intermixed to connect multiple PXI chassis
together. As mentioned previously, an individual MXI-3 or MXI-4 board
will not cable directly to a MXI-Express board.
MXI-3 and MXI-4 systems required the use of a specific boot ordering.
Is this a requirement with MXI-Express?
Yes. The requirements of the PCI bus still mandate that you must power on
secondary PXI chassis before powering on the host PC when using
MXI-Express.
With MXI-3 and several chassis connected in series (daisy chain
configuration), you were required to power on the chassis in order starting
