  • PXIe-8301

Issue Details

The PXIe-8301 has two Thunderbolt™ 3 ports. Do I need to connect both ports to my computer to obtain maximum throughput?


No, the second Thunderbolt™ 3 port on the PXIe-8301 is for daisy chain purposes only.  The second port is used to connect multiple Thunderbolt™ 3 compatible devices to a PC connected on the first port in a daisy-chain topology
