Introduction

Most industrial computer systems come with standard 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-4520/4522 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 RS-485 signals. You do not need to change your PC’s hardware or your software. The ADAM-4520 lets you easily build an industrial grade, long distance communication system with standard PC hardware. It extends the communication distance by 4000 ft. (1200 m) or increases the maximum number of connected nodes by 32.


Sebagian besar sistem komputer industri dilengkapi dengan port serial RS-232 standar. Meski bisa diterima secara luas, RS-232 memiliki keterbatasan kecepatan transmisi, jangkauan, dan kemampuan jaringan. Standar RS-422 dan RS-485 mengatasi keterbatasan ini dengan menggunakan jalur voltase diferensial untuk sinyal data dan kontrol. Konverter ADAM-4520/4522 memungkinkan Anda memanfaatkan RS-422 dan RS-485 pada sistem yang awalnya dilengkapi dengan RS-232. Ini secara transparan mengubah sinyal RS-232 menjadi sinyal RS-422 atau RS-485 yang terisolasi. Anda tidak perlu mengganti perangkat keras PC atau perangkat lunak Anda. ADAM-4520 memungkinkan Anda membangun sebuah kelas dengan mudah, sistem komunikasi jarak jauh dengan perangkat keras PC standar. Ini memperluas jarak komunikasi sebesar 4000 ft (1200 m) atau meningkatkan jumlah maksimum node yang terhubung sebesar 32.
