SUNIX SER6437A, PCI Express serial communication boards meet the PCI Express Base Specification Revision 2.0. It is compatible with PCI Express x1, x2, x4, x8 and x16 lane Bus allowing it to be installed in virtually any PC system. The majorities of today’s motherboards is not equipped with serial ports or only have one serial port. With SUNIX PCI Express serial board, users can add 2 serial ports to their system, allowing them to use serial devices further. SUNIX SER6437A card has 128-bytes onboard FIFO buffer and compatible with 16C950 UART specification. It is designed with SUNIX UART controller, SUN2212 and as well built with many of SUNIX advanced features and technologies, making it the best solution for commercial and industrial automation applications.
