UC Finder

ATTENTION

UC finder is designed solely to find IP addresses of networked Universal Communicators. It cannot be used to configure Universal Communicators over the network. If you need to configure UC’s IP address or other parameters, connect to UC’s console utility by Telnet (over the network) or serial console (using the serial console cable that came with the product).

The next time you need to run UC Finder, double click the UC Finder icon located on your PC’s desktop to launch this utility.
