The MSC-208A1 PCI Express I/O adapter provides 8 high performance 16C950-type UART compatible RS232 serial ports. It features a 1-chip solution for PCI Express boards to help increase throughput and reduce CPU loading, which is far better than current 2-chip solutions. It is designed for PC, thin client, or server to provide instant COM port expansion via the PCI Express Bus (PCIE).

PCI Express provides a scalable, high-speed, serial I/O bus that maintains backward compatibility with PCI applications and drivers. Its architecture defines a high-performance, point-to-point, scalable, serial bus at speed of 250Mbytes/sec to 4GBytes/sec (and 8Gbytes/sec in the future).

The card is fully PCI Express Plug-and-Play compatible and no IRQ and I/O address conflict problems. The MSC-208A1 provides the scalability to quickly adapt to new PCI Express technologies. It allows you to add serial connectivity as needed. The complete product line offer many choices help you to expand and make your serial network grow with your requirements.
