Simple one touch testing verifies network cabling and service. The NETcat® Pro is a digital tool for fast and accurate testing of cables, wiring and network services. Operated using a back-lit touch screen display, the Pro 500 not only tests wiring continuity and confirms pair allocation, but measures the length of cables and determines if network service is accessible. When used with the NC-510 accessory kit containing seven (7) expansion remote test modules, the NETcat® Pro can uniquely test coax or twisted pair jacks from a central location eight (8) at a time. Using either a finger tip or the built in stylus pen, the screen can be used to control and display a range of tests from fault finding to TDR length measurement.
