Review on JOAUIAX Multifunctional Collation Telephone Bag JWT01 by Robert Howell

This is a good pair of wired detector and tracker. It can diagnose both phone cables and Ethernet cables. The transmitter unit has the function of sending a serial signal to check the wiring order or a tone to trace the cable. The receiver receives the signal from the TX and either displays the sequence or plays the audio indication. Both TX and RX have a built-in flashlight. Good tool for server maintenance.
