Features DisplayPort Cable Tester: An Essential Tool for A/V Cable Installers Avoid the problems and costly troubleshooting caused by a bad DisplayPort cable. This DisplayPort tester allows you to quickly and accurately verify DisplayPort and Mini DisplayPort cables before installing them behind walls and in other tough-to-reach places. It's recommended for installers of digital signage applications and home theater systems who need to verify straight or crossed connections and open or short circuits. Features 2 Adjustable Test Modes: Continuity and Sweep Quickly validating whether a faulty DisplayPort cable is the issue in a malfunctioning application can save you time, trouble and money, as can detecting a faulty cable before you install it. The T040-001-DP flips from sync testing (Continuity) to step-by-step testing (Sweep) at the touch of a switch. It displays a 19 pin-to-pin wire map and shield connection status to ensure mapping continuity and proper configuration. The DisplayPort tester is compatible with DisplayPort versions 1.0 through 1.4 and cable lengths up to 49 feet (15 meters). Easy to Store in Your Toolbox and Take to the Job Site This DisplayPort tester consists of a main tester unit and a removable remote identifier that are secured in a protective carrying case when not in use. The tester units are powered by a standard 9-volt battery (not included). To test a cable that has already been installed, separate the two units and connect them to each end of the cable. One-Year Warranty The T040-001-DP is backed by a one-year warranty, ensuring reliability and performance.
