2-Port PCIe RS232 Adapter Card — PCI-E to DB9/DB25 Serial/Parallel Converter

Overview: Add two RS232 serial ports to a desktop PC using this PCI-Express I/O card. The board provides DB9 and DB25 connectors to expand legacy serial and parallel device support. Compatibility: Built for the PCI-Express expansion bus standard used by the majority of modern desktop motherboards. Since many newer boards ship without sufficient serial or parallel ports, this card restores those connections for external equipment. Performance: Designed for demanding environments such as industrial automation, it delivers high, reliable data transfer rates. Speed: Single-Lane PCI-Express with throughput up to 2.5Gbps.
