Ethernet-Serial Server GW51C-

MAXI

1. Introduction

The Atop GW51C-

MAXI

Ethernet-Serial Server is a gateway between Ethernet (TCP/IP) and

RS-232/RS-485 communications. The information transmitted by GW51C-

MAXI

is transparent to both host

computers (Ethernet) and devices (RS-232/RS-485). Data coming from the Ethernet (TCP/IP) is sent to

the designated RS-232/RS-485 port and data being received from RS-232/RS-485 port is sent to the

Ethernet (TCP/IP) transparently.

In the computer integration manufacturing or industrial automation area, the Atop GW51C-

MAXI

Ethernet-Serial Server is used for field devices to direct connect to Ethernet network. Terminal Server

(main control program run in GW51C-

MAXI

) transforms whatever data received from RS-232/RS-485 to

TCP/UDP port then connect devices to the Ethernet network via a single application program or multiple

application programs.

Many control devices provide the ability to communicate with hosts through RS-232/RS-485 however

RS-232/RS-485 serial communication has its limitations. For one, it is hard to transfer data through a long

distance. With Atop GW51C-

MAXI

, it is possible to communicate with a remote device in the Intranet

environment or even in the Internet and thus, increases the communication distance dramatically.

GW51C-

MAXI

from Atop Technologies Inc. offers one RS-232/ RS-485 port, one RJ45 Ethernet and

Watch-Dog Timer etc.
