10.1 Getting the IP Address from a DHCP Server
The module requires an IP address so it can be addressed via the ETHERNET network.
It has no IP address when delivered. As soon as the module starts up, it sends queries to
a DHCP server to get an IP address.
If there is already a DHCP server on the network, ask your network administrator for the
IP address assigned to the module and use its MAC address for identification.
Using a DHCP Server on Your Computer
If no DHCP server exists on the network, or you want to use a DHCP server on the local
network for test purposes, you can use Open DHCP Server, for example.
Please note:
• If a DHCP server is installed on your computer, you should never connect it to a larger
network. Since global networks usually have a DHCP server, collisions could occur
and crash the network.
• Only use a DHCP server on your computer if there is no DHCP server on the network.
Installing and Using Open DHCP Server
You can install Open DHCP Server on your computer. To configure the DHCP server,
you need the IP address of your computer's network connection. On Windows, you can
use the ipconfig command to show your computer's IP address(es).
Proceed as follows:
1. Launch the "ETHERNET Device Configuration" software.
2. Download Open DHCP Server from
3. Install Open DHCP Server.
4. In the Open DHCP Server installation directory, open the OpenDHCPServer.ini
file in a text editor.
5. Under [LISTEN_ON], enter the IP address of your computer's network card on which
the DHCP server should work.
6. Save the OpenDHCPServer.ini file.
7. Under [RANGE_SET], enter the IP address range the DHCP server is allowed to as-
sign.
8. Then run the RunStandAlone.bat file.
ð The DHCP server is now ready.
ð In the output window, Open DHCP Server shows the query and the assigned IP ad-
dress.
