  • What's Included
  • The GWC Technology FP4220 adds two RS-232 serial ports to your full height or low profile computer through a PCI Express slot. The FP4220 PCI Express based serial card turns a PCI Express slot into 2 RS-232 (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 (bridge chip) serial cards. The RS232 serial adapter card is compatible with a broad range of operating systems.

    This card is also available in a low profile PCIe format with Two Ports or Four Ports, each sold separately.
