The CableMaster 210 is an Ethernet cable tester that is small enough to fit in your pocket. It includes a large LCD, backlit display and remote that neatly docks inside the local tester. For troubleshooting Ethernet cable or testing after cable installation, the CableMaster 210 also includes a local and remote cable tester to connect to each end of a cable. A click of the large “OK” button starts the cable test. The results show pass/fail, as well as the resulting wire map diagram, shorts, opens, miswires and length of cable. For finding wires in a bundle of cables, CableMaster 210 includes a tone generator compatible with optional tone receiver Cable Probe (CP15) from Softing and up to 24 cable identifiers.
