Sunix SER6456AL PCIE 4-Port Serial RS-232 Card - Low Profile

Sunix SER6456AL PCIE 4-Port Serial RS-232 Card - Low Profile
SUNIX SER6456AL, 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 any slim size PC-based system with low profile bracket structure.

The majorities of todays motherboards is not equipped with serial ports or only have one serial port. With SUNIX PCI Express serial board, users can add four serial ports to their system, allowing them to use serial devices further. SUNIX SER6456AL card has 128-bytes onboard FIFO buffer and compatible with 16C950 UART specification. It is designed with SUNIX UART controller, SUN2410 and as well built with many of SUNIX advanced features and technologies, making it the best solution for commercial and industrial automation applications.

Expands 4 independent RS-232 serial ports with communication speeds up to 115.2Kbps.
With high reliable SUNIX SUN2410 native PCI Express 16C950 UART controller.
