The MSC-216A PCI Express I/O adapter provides 16 high performance 16C950-type UART compatible RS232 serial ports. It is designed for a 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 a speed of 250Mbytes/sec to 4GBytes/sec (and 8Gbytes/sec in the future).
The card is fully PCI Express Plug-and-Play compatible and has no IRQ and I/O address conflict problems. The MSC-216A provides the scalability to quickly adapt to new PCI Express technologies allowing you to add serial connectivity as needed. The complete product line offers many choices to help you expand specific requirements for your network.
