Check the listing for details. Ideal 62-200 LinkMaster RJ45 CAT5E/6 Ethernet Wiremapper Tester. Condition: New. Listed at 95.71 USD. Use the IDEAL LinkMaster Wiremapper to identify wiring and continuity errors in twisted pair cabling. Wiremappers are used to verify if the cable is physically terminated properly at both ends and that there are no major cable defects present in the cable, such as cut conductors, that would prevent signal continuity. Colored LED lights identify pass/fail conditions of each pair of wires in RJ45 8-conductor cables. This tester is used for testing RJ45 connector cables terminated to CAT 3/5/5E/6/6A twisted pair cables. When the test is activated, LinkMaster checks each pair of the cable for any opens (unterminated or cut conductors), shorts (cut or nicked conductors that come into contact), miswires (wires out of order–not consistent at both ends), reversals (1 pair miswired), and split pairs (wired correctly but using wrong conductor order and grouping). Any pair that fails is indicated with a red LED light for easy visual indication of a non-passing cable. Shield continuity can also be tested on shielded connectors and cables. The Debug feature cycles through each pair so you can see the pass/fail status of each pair 1 at a time. Single button operation simplifies the use of the LinkMaster.
