ADAM-4521 Addressable RS-232 to RS-422/RS-485 Converter Module

Download the ADAM-4521 data sheet.

Overview

The ADAM-4521 is an intelligent RS-422/485 to RS-232 converter specifically designed to connect RS-232 devices to an RS-422/485 network. RS-232 is the most common transmission standard. Although widely available on most computer systems, measurement equipment, PLCs, and industrial devices, its transmission speed, communication distance, and especially networking capability are limited due to unbalanced transmission. The ADAM-4521 addressable converter solves this problem and lets you easily build up an RS-485 network with your RS-232 devices by assigning each one an address for easier communication.
