Sunix SER6437AL PCIE 2-Port Serial RS-232 Low Profile Card (DB9M)

SUNIX SER6437AL, PCI Express serial communication board meets the PCI Express Base Specification Revision 2.0, allows users to add or expand two RS-232 COM ports on PC-based system to use serial devices further. It is compatible with PCI Express x1, x2, x4, x8 and x16 lane Bus allowing it to be installed in any PC-based system with low profile bracket structure. The majorities of today’s motherboard is not equipped with serial ports or only have one serial port. With SUNIX PCI Express serial board, users can add one serial port to their system, allowing them to use serial devices further. SUNIX SER6437AL card has 128-bytes onboard FIFO buffer and compatible with 16C950 UART specifications. 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.
