Product Details

PEX2S952 PCI Express RS232 Serial Adapter Card

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 to 4.11.x).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.Backed by a Lifetime warranty and free lifetime technical support.

PCI ExpressCards RS-232

PCI Express (PCIe) is a serial I/O technology that has been designed to deliver significantly more data than the existing PCI standard, with a transfer rate of 2.5Gb/s in each direction per lane. PCIe is expected to replace PCI on all new personal computers to the end of this year. Initially, personal computers will have both PCI and PCIe slots available. Drivers for all popular operating systems including Windows 7.
