Extend modern systems with the serial connectivity legacy infrastructure still depends on. This 2-port PCI Express serial card adds two RS-232 DB9 ports through a PCIe slot, giving IT teams a clean way to support older peripherals, console access, and industrial control equipment from current desktops and servers. Built around dual-channel 16C1050 UART architecture, the card is designed for compatibility with 16C1050 devices and includes a 256-byte deep FIFO per transmitter and receiver to help maintain stable serial communication. With a maximum data transfer rate of 460 Kbps, it provides the throughput needed for common RS-232 deployments without overcomplicating the install. The low- and full-profile support makes it easier to fit into a wide range of chassis, from compact workstations to standard tower systems. For organizations that still rely on serial interfaces for manufacturing, service, networking, or lab equipment, this card offers a practical expansion path that preserves existing workflows and avoids replacing functioning hardware. TAA compliance also makes it suitable for procurement environments with sourcing requirements.
