GW51C-MAXI Serial Server

1. Introduction

GW51C-MAXI Serial Server is a gateway between Ethernet (TCP/IP) and RS-232/RS-485
communications. The information transmitted by GW51C-MAXI Serial Server 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 GW51C-MAXI Serial Server
is used for field devices to direct connect to Ethernet network. Terminal Server (main control program run
in GW51C-MAXI Serial Server) 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 GW51C-MAXI Serial Server, 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 Serial Server from Atop Technologies Inc. offers one RS-232/ RS-485 port, one RJ45
Ethernet and Watch-Dog Timer etc.
