The Ideal 33-856 VDV Tester is an LCD based all-in-one basic Voice-Data-Video tester for verifying proper wiring of low-voltage and data communications cables. The primary function of the VDV is the wiremap test. The wiremap test visually shows, pin by pin, whether a cable is terminated properly at both ends and if there is continuity from end to end. The VDV can test Data/Ethernet RJ-45 (8P8C), Voice/Phone RJ-11/12(6P6C/6P4C), and Video/coax cables. The LCD visually displays "PASS" or "ERROR" after each test to verify if the cable is terminated correctly.
In Data mode, the RJ-45 port tests RJ-45 connector cables terminated to Cat 3/5/5e/6/6a twisted pair cables. When the test is activated, VDV checks each conductor of the cable for any opens terminated or cut conductors), shorts (cut or nicked conductors that come into contact), miswires (wires out of order - not consistent at both ends), reversals, or split pairs (wired correctly but using wrong conductor order and grouping). VDV can accurately identify and alert the user to uplink/crossover cables.
