Introduction

SUNIX SER4456A, PCI Express serial communication boards meet the PCI Express Base Specification Revision 1.1. It is compatible with PCI Express x1, x2, x4, x8 and x16 lane Bus. 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 4 serial ports to their system, allowing them to use serial devices further. Windows 2000 and later and Linux 2.4x kernel and later support the PCI Express bus system. SUNIX PCI Express Serial Board is the advanced and high efficient solution for commercial and industrial automation applications
