StarTech 1 Port Low Profile PCI Express DB-9 RS232 Serial Card

The PEX1S553LP PCI Express Serial Card turns a PCI Express slot into an RS232 (DB9) serial connection. The card is constructed using a native single chip design that lets you harness the full capability offered by PCI Express (PCIe), while reducing the load applied to the CPU by as much as 48% over conventional bridge chip serial cards.

1 Port Serial Card:
Serial controller card w/ 16550 UART based on ASIX MCS9922CV-AA, allows 1x DB9 port w/bi-directional RS232 speeds up to 460.8Kbps per port, available 256 byte FIFO buffer; Upgraded version of our popular card PEX1S552LP

Optional Configurable Power:
PCI Express RS232 serial adapter card provides choice of 12v, 5v, or none through pin 9
