The device comprises a main module and detachable remote. To test a cable, its ends must be connected to the appropriate RJ45 (UTP/STP), RJ11 or USB jacks in both units. BNC leads must be connected to the plug on the top of the main module and terminated using the BNC remote jack (included) before testing. Pressing the test button generates an audible beep and one of several LED indications on the front panel, denoting various connection statuses, including crossover.
