This PCI Express based serial adaptor card allows you to turn a PCI Express slot into four RS232 (DB9) serial connections. The adaptor card is based on a native single chip design, that allows you to harness the full capability of PCI Express (PCIe) - providing optimum reliability and speed, and reducing the load applied to the cpu by as much as 48% over conventional serial cards.
