The Hobbes LANtest RJ45 Basic Network Cable Tester is one of the simplest and most affordable network cable wire mapping devices available. Use it to determine the actual cabling configuration for Cat5, coaxial and modular telephone cables. Wiring faults such as open wires, shorts, mis-wired and crossed wire pairs can be clearly identified. Conveniently perform all the above tests with the remote unit (Remote Terminator) included in the scope of delivery.
