1. 5 in 1 Cable Tester RIK T05 User Manual RTK T05 User Manual 1 INTRODUCTION The 5 in 1 Cable Tester tests 5 common LAN and Computer cables It tests installed cables or patch cords with RJ 45 RJ 11 1394 USB and BNC connectors It is intended to test cables with straight through connections not cables with reversed or transposed connections like some LAN crossover cables or reverse wired telephone cables 2 SAFETY RULES AND WARNINGS N WARNING This tester is not intended for use on powered circuits Attaching this tester to a powered circuit can result in damage to the tester or injury to the user Read all instructions in this manual before using this tester Failure to do so may result in damage to the tester or injury to the user e Do not use this tester with hits case open or with parts removed Doing so may damage the tester and or injure the user e When using this tester in schools and workshops responsible teachers or skilled personnel must control the usage of this tester Failure to observe this precaution may result in damage to the tester or injury to the user e Follow the recommendations of any Trade Organizations or Regulatory Agencies whose scope encompasses the use of this tester Failure to do so may result in damage to the tester or injury to the user e Do not open this tester for maintenance without first disconnecting it from all external circuitry Failure to observe this precaution may result in da2. 5 in 1 indicates the cable is not working but my LAN works OK Installed LAN cables with RJ 45 connectors that have been is service and working OK may test as Open Shorted or Crossed Here s why The EIA TIA 568 standard for LAN cables only uses 4 of the wires in the eight wire cable The other 4 wires in the cable may have faults But these will not affect the operation of the LAN The 5 in 1 tests all of the wires in the LAN cable And identifies the faults Even though these wires may not being used in the LAN system Not all LAN cables are wired straight through crossover cables used on LAN are purposely mis wired With their Receive and transmit wires cross over The 5 in 1 will test this as a bad cable But it may work just fine as crossover cable The 5 in 1 says my cable is good but it does not work on my LAN Many cable testers like the 5 in 1 only perform continuity style tests open short crossed etc Ethernet LAN cables are constructed in a special way The 8 wires inside are grouped into 4 pairs of 2 wires each Not only must the 8 wires connect from end to end of the cable the pairs in the cable must connect to specific pins of RJ 45 plugs on to the ends of cable ignoring the pairing as described in EIA TIA 568 and the cable will test OK But when the cable is tried on the LAN it does not work This is because the lack of the proper pairing causes excessive cross talk in the cable preventing the LAN from working This type of c
