The MPEX2S952 2-port Mini PCI Express serial card turns a mini-PCIe slot into two RS232 (DB9) serial ports - a cost-saving solution for adding legacy serial support for embedded systems that aren't normally compatible.
The adapter card features a native PCI Express single chip design, which allows you to take advantage of full PCI Express 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 .
Designed and constructed to provide long-lasting durability and reliability, the 2-Port Mini PCI Express RS232 Serial Card is backed by our Lifetime Warranty and free lifetime technical support.
