This 4 port PCI Express based serial adapter card lets you turn a PCI Express slot into four RS232 (DB9) serial connections. The adapter 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 while reducing the load applied to the CPU by as much as 48% over conventional serial cards. The RS232 Serial Adapter Card is compatible with a broad range of operating systems, including Windows 2000/XP/2003/Vista, Linux Kernel 2. 6. 11 and up, as well as MAC OS 10. 4 and above. To ensure broad compatibility, the 4 port PCIe Serial Adapter card includes an optional low profile bracket that allows the card to be installed in virtually any computer case – making it easier to add serial ports to a PCI Express enabled computer, regardless of the size of the computer case.
