PXIe-8399. The PXIe-8394 backplane connection is limited to Gen 3 x8. Figure 7. Example of a MXI-Express Gen-3 x16 System Expansion Topology Using a PXIe-8394 in Each Chassis Systems need not be exclusively star or daisy-chain. It is generally preferable to use a star topology, but you can daisy-chain or star additional chassis as needed. - Page 9 Port 1 of the PXIe-8398 and PXIe-8399 is upstream facing, meaning it is the link going toward the host. This means it is connected to a PXIe-8394, PCIe-8398, or a downstream facing port of a PXIe-8398 or PXIe-8399. MXI-Express Gen-3 x16 User Manual | © National Instruments | 9...
