Our Ethernet interfaces come with a factory IP address 192.168.1.20. An IP address is a number that is unique to any particular device within a network. In order to communicate with your interface, you need to manually set your computer’s IP address to 192.168.1.xx, where “xx” is any number other than 20. You cannot have both devices (interface and computer) with the exact same IP address, but both need to be within the same subnet (192.168.1.xx).
To configure your computer to work with our Ethernet interface:
1. Connect your IP/Ethernet interface to your computer and to its power supply (9-12V DC).
2. Change your computer’s IP address to match the interface's subnet mask. Start from Window’s Control Panel, then Network Connections. Double-click on the Local Area Network connection, then click on TCP/IP, then Properties. Change from “Automatic” to “Use the following” IP address, and type:
IP 192.168.1.xx (xx is any number larger than 10, different from 20)
Subnet mask 255.255.255.0
Leave all other fields blank, then click OK. Wait a few moments while the connection is reset between the interface and computer. Close the Local Area Network properties window.
3. Start the Sunlite software.
Once the software is open, go to the “?” menu, then About. A circular popup with the logo will be shown with a white box underneath. In this box, you should read something like this:
June 13 2006(Release date)
1 SLESA-IP (interface description in red letters)
If you can read this interface description, this means that there is good communication between the software and the interface... you are done!
If you cannot read the interface description, this means you probably purchased a simple IP-DMX converter and forgot to also connect the USB interface for the software.
If you go into the CONTROLLER menu, then STARTING PARAMETERS, you will be able to set the universe for each USB-DMX or IP-DMX interface.
Changing the IP address of the interface
If you wish to change the IP address for the Ethernet interface (default 192.168.1.20), you need to do this from the Stand Alone software (included in the installation CD). Connect the interface directly to your computer using the cross-over Ethernet cable provided, and set your computer's IP interface within the same subnet as the interface (192.168.1.xx).
Start the Stand Alone software. Go to the TOOLS menu, then IP/ETHERNET OPTIONS. The password is
In that window you will find LAN settings. Make all desired changes and close the Stand Alone software. Disconnect the interface from your computer and using a regular Ethernet cable (not provided) connect the interface to your network router. When you start the Sunlite software, you should see the same red description for the interface as you did when they were connected directly.
