The LI-7700 finder application

The LI-7700 Finder provides access to internal LI-7700 settings, many of which are duplicated in the normal software interface. It also is used to set the LI-7550 clock. To launch the application click the help question mark > About > Factory Setup… > Proceed. Upon launching the application, you will see a list of all LI-7700s and LI-7550s on your local network.

To use the LI-7700 Finder Application, connect to the LI-7700 (and LI-7550 if applicable) using the Ethernet connection. The finder application will not see devices that are connected using the RS-232 serial connection.

Caution: The LI-7700 Finder Application provides access to advanced settings. Changing some of these settings may undesirably alter the performance of your LI-7700. Use caution when altering these settings, and consult with LI-COR technical support personnel if you have questions.
