Introduction

This multiport PCI Express RS232 serial adapter card lets you add two RS232 (DB9) serial ports to your computer through a PCI Express (PCIe) slot, as if they were native serial ports. The dual port PCIe serial card enables you to interact with serial devices, such as card readers, printers, PIN pads, and modems, at speeds of up to 921.6Kbps.

Features

• 2 PORT SERIAL CARD: Serial controller card w/16950 UART based on ASIX AX99100, allows 2x DB9 ports w/bi-directional RS232 speeds up to 921.6Kbps per port, available 256 byte FIFO buffer & 9th data bit
• OPTIONAL CONFIGURABLE POWER: PCI Express RS232 Serial Adapter Card provides choice of 12v, 5v, or none through pin 9 w/up to 2A total; Each of the 2 ports are individually configurable
• STANDARD PROFILE & LOW PROFILE BRACKET: PCIe multiport serial card comes w/ a standard bracket pre-installed & 2x low profile brackets incl for versatile install; supports Windows XP and up & Linux
