The network kit is a practical solution for checking the functionality of telephone and CAT cables in your home network. In case of connection issues, the network tester checks the individual wire pairs to identify or rule out faults in the cable. It is a network tester for RJ11 and RJ45 cables, designed to test individual wires for continuity, short circuits, wire reversal, and cable defects. It reliably checks the functionality of 6- and 8-pin telephone and LAN cables with the following configurations: 6P6C, 6P4C, 6P2C, 8P8C, 8P4C. With the included adapter cables and adapter, coaxial BNC cables can also be tested for functionality. The ports of the main and remote units are connected to the cable being tested and indicate the status of the individual wires through LEDs. The tester features "Auto" and "Manual" modes for automatic or individual wire testing and indicates via the "G" LED whether it is a shielded cable. The network cable tester is powered by a 9V battery (not included). The delivery includes a hard case, 2 BNC-to-RJ45 cables, 1 RJ45-to-RJ45 cable, 1 BNC-to-BNC connector, and 2 RJ45-to-RJ11 adapters.
