It checks RJ45 network cable, RJ11 telephone cable, USB Type-A-to-Type-B cable, and BNC coaxial cable connections using LED pin indicators and an audible beeper. The detachable far-end remote supports installed-cable testing between two locations, while the BNC remote handles supported coaxial checks. Use it to identify opens, shorts, missing connections, crossover wiring, and conductor-order problems before commissioning or during troubleshooting. It is a continuity and wiring-map tool—not a network bandwidth certifier, PoE analyzer, cable-length meter, or energized-circuit tester.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour connector families:\u003c\/strong\u003e RJ45, RJ11, USB Type-A to Type-B, and BNC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon fault indication:\u003c\/strong\u003e checks opens, shorts, missing connections, crossover wiring, and pin order.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetachable remote:\u003c\/strong\u003e supports testing installed wiring and cables whose ends are in different locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED and audible feedback:\u003c\/strong\u003e sequential indicators show conductor continuity, with a beeper for test-result feedback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePortable design:\u003c\/strong\u003e remote stores with the main tester and the kit includes a carrying bag.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBest For \/ Typical Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEthernet patch-cable assembly and basic wiring-map checks\u003c\/li\u003e\n\u003cli\u003eRJ11 telephone-line continuity troubleshooting\u003c\/li\u003e\n\u003cli\u003eUSB printer-style Type-A-to-Type-B cable checks\u003c\/li\u003e\n\u003cli\u003eBNC coaxial cable installation and maintenance\u003c\/li\u003e\n\u003cli\u003eLow-voltage installation, IT support, CCTV service, and field maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eSupplier-stated information\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eBNC4N1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported interfaces\u003c\/td\u003e\n\u003ctd\u003eRJ45, RJ11, USB Type-A \/ Type-B, BNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRJ45 cable types\u003c\/td\u003e\n\u003ctd\u003eUTP and STP cables terminated with RJ45 male connectors; EIA\/TIA-568 pinout reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRJ11 cable types\u003c\/td\u003e\n\u003ctd\u003eMale modular connectors with 2–6 installed conductors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSB cable type\u003c\/td\u003e\n\u003ctd\u003eUSB Type-A male to USB Type-B male only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBNC cable type\u003c\/td\u003e\n\u003ctd\u003eBNC cables with male connectors; supplier literature describes 25\/50 Ω termination indication\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFault indications\u003c\/td\u003e\n\u003ctd\u003eNo connection, open, short, crossover, and conductor-order faults\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum stated test run\u003c\/td\u003e\n\u003ctd\u003eUp to 300 ft (about 91 m) for RJ45, RJ11, and BNC; actual results depend on cable and contact condition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e1 × 9 V 6F22 alkaline battery (not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow-battery indication\u003c\/td\u003e\n\u003ctd\u003eLED indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct dimensions\u003c\/td\u003e\n\u003ctd\u003eApprox. 162 × 85 × 25 mm (6.38 × 3.35 × 0.98 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct weight\u003c\/td\u003e\n\u003ctd\u003eApprox. 164 g (5.78 oz), excluding battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage dimensions\u003c\/td\u003e\n\u003ctd\u003eApprox. 225 × 110 × 43 mm (8.86 × 4.33 × 1.69 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage weight\u003c\/td\u003e\n\u003ctd\u003eApprox. 215 g (7.58 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eConfiguration Guide\u003c\/h2\u003e\n\u003cp\u003eThis listing has one standard kit.
