Single-Port RS232 Expansion

The Syba SD-PEX15021 adds one DB9 serial port through a PCI Express x1 slot. It uses the MSC9901 chipset and is compliant with PCI Express base specification revision 1.0a. The card includes a low-profile bracket for small-form-factor systems. A driver CD and manual are supplied in the box.

Industrial and Legacy Connectivity

This card suits users who need a native serial port for modems, industrial equipment or older peripherals. It supports Windows 2000, XP, Server 2003, Vista and Server 2008 in both 32-bit and 64-bit editions. It is not for builders who require multiple serial ports from a single expansion slot. It is also not for systems that lack a free PCI Express x1 connection.

PCI Express x1 Interface Decides Fit

The card installs in any single-lane PCI Express slot with throughput up to 2.5Gbps. Verify that the motherboard has an available x1 slot before purchase. The low-profile bracket allows installation in slim chassis where full-height cards cannot fit.
