STARTECH.COM MPEX4S552 4 Port RS232 Mini PCI Express Serial Card w/ 16650 UART

Add Four RS232 Serial Ports to an Embedded System through a mini PCI Express Slot. The MPEX4S952 4-Port RS232 Mini PCI Express Serial Card (16650 UART) turns a mini-PCIe slot into four RS232 (DB9) serial ports with data rates up to 921.6 Kbps - a cost-saving solution for adding serial support to embedded systems missing the functionality. A native PCIe single-chip design enables you to take advantage of full PCI Express bus capability, by providing improved speed and reliability while reducing the load applied to the CPU by as much as 48% over conventional "bridge chip" serial cards. In-band software flow control, using programmable Xon/Xoff in both directions Compliant with PCI Express base specifications revision 1.1 Native single-chip, single lane PCI Express High Performance 16650 UART Includes 4x 30cm IDC to DB9 serial cables 256-byte deep FIFO per transmitter and receiver Automated out-of-band hardware flow control using RTS/CTS Four high speed RS232 serial ports with data transfer rates up to 921.6 Kbps
