Introduction

SUNIX SDC Series, industrial RS-232/422/485 and isolated Digital I/O PCI-Express add-on card, is
designed for PC-based IoT Gateway or desktop that enables data acquisition, I/O control and
serial communication in the industrial automation. This board built-in SUNIX UART & Digital-I/O
controller, QiuNiu, and as well built with many of SUNIX advanced features and technologies. In
addition, SUNIX provides API software and SDK library, allowing users to program under
Windows 10 operating systems. The software package includes a dynamic library.dll, as well as
C, C# programming language sample codes, making it easier to develop application software.
SUNIX PCI Express Industrial I/O Control Board enriches I/O expandable capacity with
cost-efficient design; SDC4880B is the best serial and digital I/O communicating solution and
SDC0880I is the best digital I/O communicating solution to enrich your system I/O expandable
capacity for lite industrial applications.
