4Port RS232 PCI Express Serial Card w/ Breakout Cable
The PEX4S552B Serial PCI Express card lets you add four RS232 serial ports using a single PCIe expansion slot.
The serial card features a native single chip design that provides optimum reliability and speed, while reducing the CPU load by as much as 48% over conventional serial cards that utilize a "bridge chip" for communication with the host PCI Express bus - a cost-effective solution for connecting legacy serial devices to modern PCIe-enabled computers.
The (x1) PCI Express Multiport Serial Adapter Card includes a full profile and low profile bracket to ensure compatibility with both standard and small form factor computers, and is compatible with a broad range of operating systems, including Windows 2000/XP/2003/Vista, Linux Kernel 2.6.11 and up, as well as MAC OS 10.4 and above.
- Automated out-of-band flow control using CTS/RTS and DSR/DTR
- Compliant with PCI Express base specifications revision 1.0a
- Includes a full profile and low profile bracket
- Native single-chip, single lane PCI Express
- On chip 256-byte depth FIFO in transmit/receive path of each port
- Single-Lane (x1) PCI-Express with throughput up to 2.5Gbps
- Supports 1 or 2 Stop bit operation
- Supports 5-, 6-, 7-, 8- bit serial format
- Supports DOS, Windows 2000, XP 32-/64-bit, Server 2003 32-/64-bit, Vista 32-/64-bit, Server 2008 32-/64-bit, Linux & Mac OS
- Supports even, odd, none, space & mark parity
- Supports hardware and software flow control
- Supports Re-map function for legacy ports(Supported OSs only)
