Introduction

This RS232 Serial Adapter Card lets you add two RS232 (DB9) serial ports to your computer through a PCI Express (PCIe) slot. It enables you to interact with serial devices, such as card readers, printers, PIN pads, and modems, at speeds of up to 921.4Kbps.

Maximum Compatibility

With broad OS support, including for Windows and Linux, this PCI Express card is easy to integrate into mixed environments. The card comes pre-configured with a low-profile bracket, and includes an optional full-profile bracket, so installation is easy regardless of the case form factor.
