The new VDV II Series are easy to use cable testers that check the integrity of copper cables commonly found in domestic, commercial or industrial voice, data or video installations, including telephone wiring, data network and video/security cabling.
Accurate - Advanced TDR (Time Domain Reflectometry) measures cable length and provides distance to fault information
Fast - Identifies wiring errors instantly and displays the results all on one screen
Intelligent - Quickly determines which media service is running over cables, such as ISDN, PBX and PoE
Accuracy
The flagship VDV II Pro utilises TDR to accurately measure cable length and provide distance to fault information. TDR's work by injecting a signal into the cable and measuring the time for any signal to be reflected back after encountering changes in impedance caused by cable damage, open and short circuits. The recorded time is then translated into an accurate distance measurement. TDR helps to pinpoint where cabling faults occur. This speeds up fault finding as well as minimising disruption and potential damage to fixtures and fixings.
Speed
With comprehensive details on faults such as opens, shorts, crossovers and split pairs, VDV II identifies wiring errors instantly. The integrated RJ-11/RJ-12 (voice), RJ-45 (data) and coax F-Type (video) connectors allow faster testing of most types of low-voltage cables by eliminating the need for separate testers or adapters.
Intelligence
Connection issues are not always associated with cable faults, so VDV II Pro has the capability to help identify service related issues. By detecting the presence of voltage and checking polarity, VDV II Pro quickly determines which media service is running over the cable, such as ISDN, PBX and PoE (Power over Ethernet) resulting in faster fault diagnosis. Troubleshooting active Ethernet networks is also made easier with in-built network detection that displays network rate and duplex information. Furthermore, to prevent potentially costly damage to the tester all VDV II's are smart enough to know when they have been plugged into an outlet where voltage is present.
