Startech 4 Port Dsub Pcie Serial Adapter Card, Std Profile, 2Yr

A four-port D-Sub PCIe serial adapter in standard profile, purpose-built for server racks and office desktops needing RS232 connectivity without wasting multiple expansion slots. Each DB9 port handles serial devices independently, and the standard bracket fits almost any enclosure configuration. Windows and Linux drivers support immediate deployment across your network infrastructure. Four ports on one card save space and installation time compared to stacking single-port adapters. Two-year warranty protects against manufacturing defects.
