CableMaster 800 is a professional cable tester equipped with an RJ45 jack for network cables and an Ftype connector for coaxial cables. The CableMaster 800 verifies the wire map, determines the cable length and distance to the fault. The results can be saved and documented using the PC-based reporting software. In addition, CableMaster 800 offers many network diagnostics features for troubleshooting such as cable tracing, link detection up o 1Gb/s, ping, network discovery, PoE tests and much more. CableMaster 800 is perfectly suited for professional installers and network operators who are challenged with testing and troubleshooting both network (RJ45) and coaxial cabling in active networks.

The CableMaster 800 professional cable tester is highly versatile – whether during installation, to verify which outlet is connected to the appropriate port in the patch panel, after installation, for quality testing and documentation of the cabling, or for in-service troubleshooting of the network. The test results are displayed on the full-colour graphic screen in a clear and easy to understand way. Test results can be saved in the device and be exported to a PC for evaluation or documentation with the free PC reporting software.
