Parallel Port DB25 25Pin PCIE Riser Card Communication Control Cards

Parallel Port DB25 25Pin PCIE Riser Card Communication Control Cards Description

It is compatible with PCIe GEN2.0 (2.5GT/s) and has 2 ports, each with many enhanced features.
Half duplex, -422 full duplex control, can achieve bidirectional data transmission with a transmission distance of up to 1.2 kilometers, and a single port can support up to 32 more
Surge protection, photoelectric isolation protection, DC-DC protection enable it to operate normally in more demanding environments and achieve -485
The device communicates simultaneously, so it is applied in many and various situations.
Compliant with PCI Express version 2.0;PCI Express X1 supports a bus bandwidth of 2.5Gbps;Supports x1, x2, x4, x8, x16 () PCI Express slots
