In software, a multi-chassis system can be configured using Measurement and Automation Explorer (MAX). Current versions of MAX will auto-detect the additional chassis, but legacy versions will require manual configuration
The star topology requires the host PC/master chassis to have a slot available for each PXI chassis you want to control. Each PXI chassis is connected directly to an NI PCI Device for PXI Remote Control installed in the host computer. This topology has the highest throughput; however, it requires one PCI slot and one PCI Device for PXI Remote Control for each PXI chassis.
