5.5 When the installation is completed successfully, the following screen came, and presses the OK button will terminate the installation program. 13
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. 14
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 15
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. 16
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 17
Converter, otherwise the data transfer request will not be accepted by the Ethernet Converter. To erase an existing password, just leave the Access password text box blank. 6.16 User must ensure the command port number that the Ethernet I/O Setup program used is the same as the Command Port parameter which has been configured in the Ethernet I/O setup window. To verify this, click on Option Command Port as shown below. Next, when the Command Port window opens, input the command port number that is the same as the one which has been set in the setup window, and then click on OK. 18
6.17 User needs to use the right password to enter the Ethernet I/O Setup window if password protection is enabled. Click on Option Password as shown below. When the Password window opens, input the correct password that is the same as the one which has been set in the setup window, and then click on OK. 19
6.18 To exit the Ethernet I/O Setup program, click on Option Exit as shown below. 6.19 To show the information about Ethernet I/O Setup program, click on Help About Ethernet I/O Setup as shown below. 20
And the About Ethernet I/O Setup window opens, view the description shown on the screen, and then click on OK. 6.2 Configuring With Web Browser 6.21 Start web browser and search the web site using the address: 21
http://192.168.192.250, which is the default IP address of the Ethernet Converter. The web page is shown as below. Click button to go into the configuration web page. Remember to key-in the password if authorized entry is required before you click button. 6.22 The configuration web page is shown below. Please refer to 5.1 for how to setup the related parameters of the Ethernet Converter. After setting the parameters, press the button to store the modified configuration. 22
