INTRODUCTIONThis manual is to be used with a ConneXium™ ETG100 with firmware
ENGLISH
Supported Ethernet ProtocolsThe ETG supports the following Ethernet protocols:
version 2.0 or higher. For installation information, see the installation guide.
The ETG100 is a communications device that provides connectivity
between Ethernet (Modbus TCP/IP) and serial line devices, allowing
Modbus TCP/IP clients to access information from serial slave devices. It
also allows serial master devices to access information from slave devices
distributed across an Ethernet network.
•Modbus TCP/IP: Modbus TCP/IP is a combination of the Modbus
protocol, which provides master-slave communication between devices,
and TCP/IP, which provides communications over an Ethernet
connection. Modbus TCP/IP is used to exchange data between the ETG
and other compatible Modbus TCP/IP devices via TCP port 502.
•Hypertext Transfer Protocol (HTTP): HTTP is a network protocol that
handles the delivery of files and data on the World Wide Web. It
provides web server functionality via TCP port 80. Remote configuration
of the ETG and the viewing of diagnostic data is possible using a web
browser.
•File Transfer Protocol (FTP): FTP is a network protocol that provides
the ability to transfer files over the Internet from one computer to
another. FTP is used to transfer firmware updates to the ETG via TCP
port 21.
•Simple Network Management Protocol (SNMP): Based on MIB2
format, SNMP provides the ability to store and send identifying and
diagnostic information used for network management purposes via UDP
port 161 .
•Address Resolution Protocol (ARP): ARP is used to convert IP
addresses to Ethernet addresses. ARP requests are sent by the ETG to
determine if its address is a duplicate IP address (see “Duplicate IP
Address Detection” on page 6).

ACCESSING THE ETG OVER A
NETWORK
Logging into the ETG
After you set up the Ethernet parameters (see the installation guide), you
can access the ETG over an Ethernet LAN using Internet Explorer 6.0 or
higher.
ActionResult
1. Launch Internet Explorer 6.0 or higher.Opens Internet Explorer.
2. In the Address text box, type the address
of your ETG (169.254.0.10 is the default),
then press Enter.
3. Type your user name (Administrator is the
default) and password (Gateway is the
default) into the text boxes, then click OK.
4. Click Setup to access the ETG setup page,
or click Diagnostics to access the ETG
diagnostics page.
Opens the Login dialog box.
Enters the user name and password, then
opens the ETG home page.
We recommend logging out whenever you do not need access to the ETG.
To log out of the ETG configuration session, click Log Out to end your
session.

Duplicate IP Address DetectionWhile connected to your network, the ETG publishes its IP address. To

avoid any duplicate IP address conflicts, the ETG uses the Address
Resolution Protocol (ARP) to see if any other device on your network is
using the same IP address. Table 3 below explains how the ETG handles a
duplicate IP address when it is detected.
