2 Port Low Profile Native RS232 PCI Express Serial Card with 16550 UART
StarTech ID: PEX2S553LP
The PEX2S553LP low profile/half-height PCI Express Serial Card turns a PCI Express slot into two RS232
(DB9) serial connections.
The card is constructed using a native single chip design that lets you harness the full capability offered by PCI
Express (PCIe), while reducing the load applied to the CPU by as much as 48% over conventional bridge chip
serial cards.
The PCI Express RS232 Serial Adapter Card is compatible with a broad range of operating systems, including
Windows® 2000/XP/2003/Vista™/Windows 7/Server 2008 R2 (32 and 64-bit), Linux Kernel 2.6.11 and up, and
ships with a low profile/half-height bracket installed but includes an optional full profile bracket that lets you add
2 serial ports to virtually any computer (regardless of the case form factor).
This product is a replacement for our PEX2S552LP card.
Backed by a StarTech.com Lifetime warranty and free lifetime technical support.
