Overview

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 .

Backed by a StarTech.com Lifetime Warranty and free lifetime technical support.

The StarTech.com Advantage

  • The smallest form factor available, for internally adding serial ports to any embedded system
  • Native single-chip design means up to 48% less load on your CPU which is critical for small embedded PCs that use low power, low MHz CPUs

Applications

Add serial ports to industrial embedded computers and systems

Add RS232 serial control to an embedded or slim media center/media server/all-in-one PC

Add RS232 serial ports to slimline POS systems
