Product ID: PEX2S5531P
The PEX2S5531P 2S1P PCI Express Card turns a PCI Express slot into two RS232 (DB9) serial ports and one
Parallel port. The adapter card features a native PCI Express single chip design that allows you to take advantage of
full PCI Express capability, providing improved speed and reliability while reducing the load applied to the CPU by as
much as 48% over conventional serial cards which use a bridge chip design.

R2 (32 and 64-bit), Linux Kernel 2.6.11 and up, and MAC OS 10.4, this 2 Port Serial 1 Port Parallel PCI-Express
Card also features an optional low profile/half-height bracket that allows the card to be installed in virtually any
computer case, regardless of the case form factor.
This product is a replacement for our PEX2S5521P card.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
