click on setup.exe to install the Ethernet I/O Utility Program. The following screen

is displayed. Click the OK button to proceed with the next step.

5.2 When the following screen is displayed, click on the button to continue. If

you want to use a destination directory different than the default one displayed on

the screen, just click on Change Directory to locate the desired folder, and then

click on button to continue.

5.3 You can change or use the default folder name displayed on the screen and then

click on Continue to start copying files.

5.4 The following screen shows the copying progress.

5.5 When the installation is completed successfully, the following screen came, and

presses the OK button will terminate the installation program.

6. Configuring The Ethernet Converter

6.1 Configuring With Ethernet Converter Setup Program

6.11 To start Ethernet Converter Setup program, click on StartProgramsEthernet

Converter Utility Ethernet_Converter_Setup

6.12 The Ethernet I/O Setup window is shown as below.

6.13 Click on the button to search all the Ethernet Converter connected

in the same subnet using the UDP broadcast protocol. When the search is finished,

the information about all Ethernet Converters found will be listed in the text box as

shown below.

6.14 Double click on the desired Ethernet Converters whose configuration is to be

modified, as shown below.

Double click on the

desired Ethernet

Converter

6.15 The following window is displayed after double click on the desired Ethernet

Converter which allow user to modify the configuration of the selected Ethernet

Converter.

Please refer to the following description for setting up the parameters of the Ethernet

Converter.

 Local IP:

The IP address of the Ethernet Converter on the TCP/IP network. The default

Local IP address is 192.168.192.250. This address should be unique. Ask your

network administrator for assistance, if in doubt.

 Subnet mask:

Identifying the network class which the Ethernet Converter belongs to. The

default Subnet mask is: 255.255.255.0. Ask your network administrator for

assistance, if in doubt.

 Gateway IP:

The IP address of the router. The default Gateway IP address is:

192.168.192.254.

Ask your network administrator for assistance, if in doubt.

 DHCP client:

If this option is enabled, that means the IP address, Subnet mask and Gateway

IP address of the Ethernet Converter are set dynamically by the DHCP Server.

If the setting cannot be got from the DHCP server successfully, the Ethernet

Converter will use the last setup parameters for its configuration. The possible

reason of this case is that the DHCP server is shutdown or not available. Ask

your network administrator for assistance, if in doubt.

 SIO Port, Type:

The local port number of the Ethernet Converter to be contacted by other

devices. The default port number is 502, which is reserved for Modbus/TCP

protocol that Ethernet Converter supports only. And default communication

mode for Ethernet Converter is TCP Server, which made Ethernet Converter

operate at the Passive or the TCP listen mode to receive TCP connection

requests from the remote client device.

 Command Port:

The Ethernet Converter supports the command mode, which user can use to

setup the parameters or get the information of the Ethernet Converter with

UDP protocol from the remote host. The default Command Port number is

65535. The command port of the Ethernet Converter should be set correctly

while using the command mode. Please refer to appendix 1 for further

information.

 Setup password:

This password protects the Setup window of the Ethernet Converter from

unauthorized entry. To erase an existing password, just leave the Setup

password text box blank.

 Access password:

If this password is configured, the remote host needs to send this access

password one second periodically to the Check Status Port of the Ethernet
