This multipurpose cable tester and tracer is a tool to help professionals and technicians test and diagnose problems with various types of network cables. This includes RJ45 Ethernet cables, UTP (Unshielded Twisted Pair) cables, and BNC (Bayonet Neill-Concelman) coaxial cables.

The cable tester and tracer typically consists of two parts: a scanner and a receiver. The scanning mode allows users to connect a cable to the tester. The receiver will sound an alert as you move the receiver closer to the other end of the cable. This tool is useful for tracing connections from a wall port to patch panels or networking equipment. By injecting at one end of the cable and indicating at the receiver with the LED indicator, the test mode (LAN only) can be used for shorts and cross-testing. The tester includes an RJ11 cable with alligator clips. Also includes a carry case, 12cm RJ45 to coax cable, 12cm RJ45 cable, 2× 9V batteries, and an earphone.
