CHAPTER 2: OVERVIEW
2.1 INTRODUCTION
Universal Serial Bus (USB) is the common interface used in today’s PCs, replacing the familiar serial ports. However, many commercial
and industrial devices still use the RS-485 interface. To connect these devices to newer PCs, you need a simple and reliable conversion
solution. The IC830A and IC831A offer this solution in a space saving, USB-port powered package.
Simply plug the converter into an available USB port on your computer or USB hub and install the drivers supplied on CD ROM. The device
will show up as an additional COM port in the Windows Device Manager, which is fully compatible with your Windows applications.
A 3.2-foot (1-meter) USB cable is included.
2.2 FEATURES
