Portable cable tester for RJ45 RJ11 RJ12

This portable cable tester checks RJ45 Ethernet cables and RJ11 or RJ12 telephone cords for open circuit, short circuit, miswiring and cross-connection faults. It suits network installers and DIY users who need a quick continuity check on Cat5 or Cat6 UTP runs in home or office environments.

Separate main and remote units for long runs

The tester splits into a main unit and a remote module so you can verify wall-embedded or patch-panel wiring without carrying the whole device to the far end. LED indicators light sequentially to show each pin status, letting you locate faults along extended cable paths.

Confirm connector types and battery before ordering

Ensure the cables you plan to test terminate in RJ45, RJ11 or RJ12 plugs, as other connector styles are not supported. Note that the unit requires a 9V battery which is not supplied, so have one ready for immediate use.

Questions about this item

How long can the main and remote units of this cable tester run on a single battery during all-day use?

The tester is powered by an internal battery that is not included with the unit, so runtime depends on the specific 9V cell you install.

What cable types must I already have to use the SMUGDESK tester for continuity checks?

You need the RJ45 Ethernet patch cords or installed Cat5 and Cat6 UTP runs, plus any RJ11 or RJ12 telephone cords you want to verify.

Will the LED pin-sequence display work correctly when testing older Cat5 runs alongside newer Cat6 cables?

Yes, the tester supports both Cat5 and Cat6 UTP standards and lights each pin sequentially to show wiring status on either cable type.
