SW5001 Wireless Serial Server

1. Introduction

Atop SW5001 Wireless-Serial Server is a gateway between wireless LAN or Ethernet (TCP/IP) and

RS-232/RS-485 communications. It allows almost any serial device to be connected to a new or existing

wireless network. The information transmitted by SW5001 is transparent to both host computers (IP

network over wireless LAN or Ethernet) and devices (RS-232/RS-485). Data coming from the wireless

LAN or 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 Wireless or Ethernet (TCP/IP) transparently.

In the computer integration manufacturing or industrial automation area, Atop SW5001 Wireless Serial

Server (Throughout the manual, an abbreviated form “SW” will be used) is used for field devices to direct

connect to Ethernet network. Terminal Server (main control program run in SW) transforms whatever data

received from RS-232/RS-485 to TCP/UDP port then connects devices to the IP 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 instance, it is hard to transfer data through a

long distance. With SW, 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 IP network by Telnet, web browser,

or Window utility. Packed in a rugged DIN Rail mountable case and 9~30V DC power input range, SW is

ideal for almost any industrial and manufacturing automation.
