Ethernet-Serial Server

GW5120

1. Introduction

1.1. Overview

GW5120 Wireless Serial Server is a gateway between wireless LAN or Ethernet (TCP/IP) and

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

existing wireless network. The information transmitted by Serial Server is transparent to both host

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

wireless LAN or Ethernet (TCP/IP) is transmitted to the designated RS-232/RS-485 port and data

from RS-232/RS-485 port is transmitted to the Wireless or Ethernet (TCP/IP) transparently.

In the computer integration manufacturing or industrial automation area, Wireless Serial Server is

used for field devices to direct connect to network. Terminal Server (main control program run in

GW5120) 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 GW5120, 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 9~48V DC power input

range, GW5120 is ideal for almost any industrial and manufacturing automation.

1.2. Features

Dual-port DIN-Rail mounting module.

Metal housing with IP50 standard.

15KV ESD protection for serial ports

IEEE 802.11g 54Mbps wireless network connectivity

Support UDP, TCP server and client protocols for Virtual COM mode and pair connection

Selectable RS-232/RS-485/RS-422 serial mode by software

Configurable via console, telnet, built-in web server and Windows-based utilities

Standard 2.4GHz High-gain antenna

Upgradeable firmware via network

2.4. Installation Procedures

Prepare necessary cables, DC power adapter and serial connector.

Place GW5120 under the access point signal coverage area, or connect GW5120 to Ethernet

cable with RJ45 connector.

Connect GW5120 serial port to a serial device; make sure the connector and wiring of RS-232

is correct.

Plug in GW5120 to DC 9-48V power source (with DC-jack or 3-pin terminal bock connector),

buzzer will beep and the RUN LED will blink if GW5120 functions normally. For LED Status

sees Appendix D4.

Use SerialManager utility from the product CD to check the status of GW5120. If it starts up

successfully, IP and MAC address of GW5120 will be displayed. IP address, subnet mask and

gateway can also be set by SerialManager.

3. Initial IP Configuration

Unit basic settings will be covered in this chapter.

3.1. Default Settings

The GW5120 has two IP addresses one for Ethernet interface and another one for wireless network

interface. These default settings are shown from under information

Default IP addresses

Table 1. Default settings of the GW5120 device

NOTE: Unit can be reset to factory default by pressing the reset button for 5

seconds.

Warning: Do NOT set LAN and WLAN IP addresses in the same subnet. That may

cause unexpected networking problem.

3.2. IP Assignment

3.2.1. Configure IP by SerialManager Utility

Use SerialManager which comes with product CD for following functions. For more details about

SerialManager, please see Appendix B1.

To find device by IP address or MAC address. Get unit’s current IP from table list.

To assign IP, network mask and gateway.

To assign ID, Password and Host Name.

Fig 2. IP settings for SerialManager Utility tool

Note: All settings were NOT changed if user ID or password was incorrect.

Unique IP address must be assigned on the device. If the same IP address is used on multiple

devices in the same subnet, user must correct the mapping between MAC address & IP address by

using ARP commands.

ARP commands

ARP (address resolution protocol) commands can be used to assign a static IP address on

GW5120 with its hardware MAC (media access control) address. The MAC

address"0060E9-xxxxxx" is printed on the rear side of GW5120. The following figure shows how to

use ARP command on MS-DOS command prompt window.

Example: Set IP 10.0.50.101 to MAC address 00-60-E9-00-79-F8.

Fig 3. Map IP address to MAC address by ARP Command
