PCIe x4 Gen 2 cable adapter with PCIe switch (including NT port and DMA controller) operates in upstream or downstream mode with DIP switch setting change.
PCIe cable adapters install easily into a computer's PCIe slot. A PCIe cable can then be plugged into the adapter to extend the PCIe bus from the motherboard to an external device, like an expansion enclosure or storage device. The PCIe x4 adapter has an 8-lane switch with built-in DMA controller and extends the PCIe bus at 20Gb/s with extremely low latency because there is no conversion software.
