UC Finder

The EM-1240-LX comes with a UC Finder utility, which has the sole purpose of searching the LAN or intranet for the EM-1240-LX units.

For most of the applications, it is not easy to remember the IP addresses of Universal Communicators connected to the LAN. This is especially true for some problem solving and testing in the field. The UC Finder utility broadcasts messages over the LAN to search for IP addresses of Universal Communicators connected to the LAN. UC Finder searches for the class of MAC addresses assigned to Universal Communicators. The EM-1240-LX supports the GUI-style Windows UC Finder, and a command line utility for Linux environments.

In this chapter, we discuss the following UC Finder topics:

Windows UC Finder

Linux UC Finder
