2 Port Native PCI Express RS232 Serial Adapter Card with 16950 UART
StarTech ID: PEX2S952
The PEX2S952 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, including Windows®
and Linux (Kernel 2.6.11 and up).
Plus, the adapter card includes an optional half-height/low profile bracket that allows the card to be installed in
virtually any computer case – making it that much easier to add serial ports to a PCI Express enabled computer,
regardless of the size of the computer case.
