The PEX2S952 PCI Express based serial card turns a PCI Express slot into 2 RS-232 (DB9) serial connections. The adapter card features a native single-chip design, which harnesses the full capability of PCI Express (PCIe) for optimum reliability and speed, while reducing CPU load by up to 48% compared to conventional bridge-chip serial cards. It is compatible with a broad range of operating systems, including Windows® and Linux (Kernel 2.6.11 and up), and MAC OS 10.4 and above. The card includes an optional half-height/low-profile bracket for installation in virtually any computer case, making it easy to add serial ports to a PCIe-enabled computer regardless of case size. It supports a data transfer rate up to 460.8 Kbps per port and features a High-Performance Dual Channel Oxford 950 UART with 128-byte deep FIFO per transmitter and receiver. It also supports selectable power output on pin 9 for connected serial devices.
