StarTech PEX2S952 overview

  • 1Description

The 2-Port RS-232 Serial PCIe Adapter Card with 16950 UART from StarTech turns a PCIe slot into two RS-232 (DB9) serial connections. The adapter card is based on a native single chip design that provides optimum reliability and speed, while reducing the load applied to the CPU by as much as 48% over conventional (bridge chip) serial cards. The serial adapter card is compatible with a broad range of operating systems, including Windows and Linux (Kernel 2.6.11 and later). Furthermore, it includes an optional half-height/low-profile bracket that allows the card to be installed in virtually any computer case, making it easier to add serial ports to a PCIe-enabled computer, regardless of the size of the computer case.

Selectable power output on pin 9 for the serial port
Features two high-speed RS-232 serial ports with data transfer rate up to 460.8 Kb/s
Compliant with PCIe base specification revision 1.0a
Native single-chip, single-lane PCIe offers increased speed and reduces CPU load by up to 48%
Includes both standard and half-height/low-profile mounting brackets to ensure easy installation into almost any system
High performance dual channel Oxford 950 UART
128-byte deep FIFO per transmitter and receiver
Automated in-band software flow control using programmable Xon/Xoff in both directions
Automated out-of-band hardware flow control using Tx/Rx/RTS/CTS/DSR/DTR/DCD/RI/GND


Self service automated machines and kiosks to control serial devices such as scales, touch screens, magnetic card readers, bar code scanners, receipt printers, and label printers
POS retail applications in grocery stores, and any other retail store to control keyboards, cash drawers, receipt printers, card readers/card swipes, scales, and elevated displays on poles
Bank teller workstations in either full profile or low-profile versions to control serial devices such as cash drawers, card readers/card swipes, printers, keypads/pinpads, and pen pads
Standard ATM automated teller machines to control keypads, receipt printer, card readers/card swipes, touchscreen LCDs, camera control, and more
Used to control multiple surveillance/security cameras in a parking structure, an office building, and more
