Description



This item is brand-new, factory sealed.

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.

Maximum Compatibility

With broad OS support, including for Windows and Linux, this 2 port PCI E serial card is easy to integrate into mixed environments. The card comes pre-configured with a full-profile bracket, and includes optional low-profile brackets, so installation is easy regardless of the case form factor. This card is a direct replacement for PEX2S952.
