1. Introduction
Atop GW51W-MAXI Wireless Serial-Ethernet Server is a gateway between Ethernet (TCP/IP) and
RS-232/RS-485 communications. It allows almost any serial device to be connected to a new or existing
Ethernet network. The information transmitted by GW51W-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 GW51W-MAXI
Serial-Ethernet Server is used for field devices to direct connect to Ethernet network. Terminal Server
(main control program run in GW51W-MAXI) transforms whatever data received from RS-232/RS-485 to
TCP/UDP port then connects 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 GW51W-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.
Flexible configuration options enable this unit to be setup remotely over Ethernet by Telnet, web browser,
or Window utility. Packed in a rugged DIN Rail mountable case and 9~30V DC power input range,
GW51W-MAXI is ideal for almost any industrial and manufacturing automation.
