User's Manual: Isolated, RS232 / RS485 to USB Converter. Model SC11U

Introduction

The SC11U allows you to connect your Serial devices to various systems by using a USB (Universal Serial Bus )
Interface. The Serial port is RS232 / RS485 & RS422 configurable. With Auto Detect and Auto baud rate function
SC11U is able to automatically detect the data flow and switch the direction of the data lines as well as to
automatically configure RS422/485 signals to any baud rate. 3000VDC Optical Isolation and Surge-protection on each
data line gives the interfacing devices protection from high voltage spikes. It draws Power from the USB port & does
not need any external adapter. SC11U supports speed upto 115.2 Kbps. It is fully compatible with USB V1.0 to 2.0
