Cable TestThe Cable test can help you determine cablelength and status, wiremap patch and structuredcabling, and locate cables. The Cable test tab canperform tests using the configurationsdescribedin this section.

With an unterminated cable test, you can determ-ine length, shorts, and splits and locate opens.With a terminated cable test using the internalWireMapping Port or aWireView accessory, youcan identify cable length, shorts and opens, splitpairs, crossover cables, and normal or negativepair polarity.

Theminimum cable length should be 2.6 ft (0.8m)for an accurate cable test. In both the terminatedand unterminated state, fault detection is accurateto within a 2.6-ft (0.8-m) distance to fault.

NOTE: LR G2 cannot perform a cable test on acable that is connected to a switch.


Refer to Buttons and Ports as needed.

Wire MappingConnect the top RJ-45 port to a cable terminatedwith an externalWireView Cable ID accessory. AWireView#1 is included with your LinkRunner G2.AdditionalWireViews2-6 are available forpurchase.

TheWireMapper Cable Test displays the numberof theWireView attached, unless a cable faultprevents LR G2 from detecting theWireView.

A cable/drop port can be traced using aWireViewup to 300 ft/100m from the LinkRunner G2.
