6 Chapter 6 UC Finder The UC Finder utility is used to search the LAN or intranet for Moxa Universal Communicators. UC Finder comes in handy if you forget the IP address, for troubleshooting field problems, and for testing. UC Finder works by sending a broadcast message over the LAN to search for UC-7420/7410 MAC addresses. It will then query the UC-7420/7410’s for their IP addresses. Two versions of UC Finder are provided.
