  • Three-button interface gives simple, easy-to-read test results

LAN Scout Jr. 2 Cable Tester

The Klein Tools LAN Scout Jr. 2 tests RJ45 terminated cables and patch cords for installers and technicians verifying network infrastructure. It identifies wiring faults on CAT 5e and CAT 6/6A links with a clear pin-to-pin wiremap on a backlit LCD. The rugged overmold housing withstands field use while the three-button interface keeps operation simple.

Fault Detection and Tone Generation

The tester detects Open, Short, Miswire, Split-Pair, Cross-over and Shield faults across all eight conductors. A backlit display ensures readable results in low-lit areas after 10 minutes the unit powers off automatically in test mode. Tone generation offers solid or warble styles on a single wire, a pair or all conductors but requires the separate VDV500-123 probe to trace cables.

Upgrade From Basic Continuity Checkers

This unit replaces simple continuity testers that only show pass or fail without identifying the fault type. The jump is worth it when you need to locate Split-Pair errors, verify shield integrity or trace cables behind walls using the tone generator. It is not suited for certifying bandwidth performance or testing fibre optic links.

Questions about this item

Will the LAN Scout Jr. 2 test CAT 5e and CAT 6 patch cords I already have terminated with RJ45 plugs?

Yes, it tests data cables terminated with RJ45 connectors and detects Open, Short, Miswire, Split-Pair, Cross-over and Shield faults on those cables.

How can I verify the tester is giving correct wiremap results after I power it on?

The backlit LCD shows a pin-to-pin wiremap for each test; matching pin numbers on both ends confirm the cable is wired correctly.

Does the box include the tone probe needed to trace cables, or must I buy it separately?

The probe Cat. No. VDV500-123 is sold separately; the tester generates solid or warble tones on a single wire, a pair, or all eight conductors.
