LM30 LanMaster 30 Outlet Identifier
Ethernet (10/100), Token Ring and Telephone Testing with one Tool
The LanMaster 30 Outlet Identifier provides LAN/Telecom Installers and Maintainers a tool to quickly test an unknown wall outlet and identify the type of circuit. Connecting equipment to an unknown outlet can damage NICs, modems, telephones or test equipment that do not have a compatible electrical interface.
Some PBX systems can provide voltage and current levels that far exceed the limits of telecom or network devices resulting in equipment failure when connected. Knowing the type of signals present at an outlet not only protects against equipment damage, but also reduces troubleshooting time finding physical layer problems.
