ADAM-4510/4510S
RS-422/485 Repeater
Introduction
Most industrial computer systems come as standard with RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422 and RS-485 standards overcome these limitations by using differential voltage lines for data and control signals. The ADAM-4520 isolated converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. It transparently converts RS-232 signals into isolated RS-422 or RS485 signals. You don't need to change your PC's hardware or your software.
