Large System Size

You can use MXI-3 to control PXI-PCI devices on up to 255 buses from
any PCI-based system, provided the BIOS supports such a configuration.
You can use either a daisy-chain or a star configuration, with maximum
bus-to-bus distances of 10 meters (copper cable) or 200 meters (fiber-optic
