The LanMaster 20 is a Link Tester for Verifying LAN Configuration and Operation. It provides LAN installers and maintainers a tool to quickly test fast Ethernet (100baseTX) and standard Ethernet (10baseT) links. Auto-sensing, auto-negotiation and full duplex capabilities are optional requirements to the Fast Ethernet (IEEE 802.3u) standard. Knowing equipment capabilities is essential to optimizing network system performance, and the LanMaster 20 Link Tester makes this possible. In just three seconds, the LM20 decodes the link signals and displays the exact configuration of the equipment connected to the link. It also verifies link connectivity to the far end, tests for reported faults and determines polarity of the outlet or cable.
