The 2-Port RS232 PCI Express Serial Card with Breakout Cable from StarTech allows you to add two RS232 serial ports using a single PCIe expansion slot. With the included breakout cable, you can easily add two ports to a single low-profile slot.

The PCIe serial card features a native single-chip design that provides optimum reliability and speed, reducing the CPU load by up to 48% over conventional bridge-chip serial cards - a cost-effective solution for connecting legacy serial devices to PCIe-enabled computers. The multi-port PCIe serial adapter includes both full- and low-profile/half-height brackets for compatibility with standard and small form factor computers. It is also compatible with Windows, Linux and Mac operating systems.

Lower CPU load, native single-chip, single-lane (x1) PCIe design with throughput of up to 2.5 Gbps ensures optimal system performance (up to 48% less CPU load)
Included standard and low-profile/half-height brackets make the card perfect for any application, including small form factor embedded applications
Breakout cable design means that only one expansion slot is needed to add two serial ports to any system
On-chip 256-byte depth FIFO in transmit/receive path of each port
Supports hardware and software flow control
Automated out-of-band flow control using CTS/RTS and DSR/DTR
Supports data transfer rates of up to 250 Kbps on each port
Compliant with PCIe base specifications revision 1.0a
