1. at fault The user must examine the different parts of the cable to determine the cause of failure and take the appropriate steps to correct the problem Which end is bad The 4 in 1 like many cable testers cannot fine the location of the fault or even determine which end or connector is bad It simply knows that a fault 12 exists The user must locate the fault and take the appropriate action 7 4 Cables with Molded on ends Many cables have molded on ends that cannot be opened up for repair The entire cable must be replaced or the molded on end removed and replaced with a user serviceable connec tor These types of cables usually fail from Opens or Shorts They seldom fail from a Crossed connection 7 5 Cables with Crimped on RJ connectors Crimped on RJ connectors cannot be reused or repaired New connectors must be installed on the cable lf the cable being tested has just been made up or put in service and it tests as Open or Crossed the RJ connectors have probably been installed incorrectly Short very seldom occur as the result of a badly crimped RJ connector so the user should suspect a problem with the wire possibly a staple or mail through the wire or a crushed or pinched wire if the 4 in 1 indicates a short A visual examination of the RJ connectors may reveal the fault but keep in mind that what ever the cause of a connector problem i e miswiring improper stripping of the wire bad crimp etc The only solution2. cables 3 5 Remote unit stores in main unit 3 6 600ft test distance RJ 45 RJ 11 BNC 3 7 Convenient battery access 3 8 Built in battery test 3 9 LEDs indicate connections and faults 3 10 Beeper provides audible annunciation of test results 3 11 Tests shielded STP or unshielded UTP LAN cables 3 12 Test USB cables 4 SPECIFICATIONS 4 1 Cables Tested UTP and STP LAN cables Terminated in RJ 45 male connectors ElA 5 TIA 568 RJ 11 cables with male connectors 2 to 6 connectors installed USB cables with Type A flat plug on one end and type B square Plug on other end BNC cables with male connectors 4 2 Faults Indicated No Connection Short Opens crosses 4 3 Low Battery Indicator LED lights to indicate low battery 4 4 Case Dimensions 6 3x3 4x1 0 inches LxWxH 4 5 Weight 170grams 0 375lbs without battery 4 6 Battery 1 standard 9 volt alkaline battery 5 FRONT PANEL amp 4 in 1 DLAGRAM S G 1 2 34 AAA OOOCOOO0COOS RJ 45 RJ 11 USB COAXIAL CABLE SHORT skort dx CONNECTED 250 li CROSSOVER DX 50Q pa NO CONNECTION NO TERMINATOR Cattery coop O BaTTERY Low Master Unit LED Display Area BNC 10 BASE T Test Buttom RJ 11 Phone System 6 OPERATION 6 1 General Information The 4 in 1 Cable Tester performs its tests when the single button on its front panel is pressed and released 6 Status LEDs indi cate the condition of

Cross LED lights the cable has a fault Notes In the Cross mode the Numbered LEDs indicate connections but do not indicate the location of the cross RJ 11 cables used for telephone connections are often crossed Even new cables are often crossed This seldom affects the performance of standard analog telephone lines POTS Digital telephone lines and old touch tone phones may be polarity sensitive so a crossed cable may prevent then from working properly 11 7 CABLE REPAIR 7 1 7 2 7 3 General Information The following sec tion provides information to the user about common cable types common failures and repairs It is not meant to be an exhaustive study of the topic just some basic information that the uninitiated may find helpful Cable damage When a cable tests badly either the wire of the connectors or both may be at fault If the cable has been installed and working then it s likely that the wire or connectors have been abused in some way The wire portion of the cable can be damaged by being crushed under the left of a desk stretched pulled sharply around a corner punctured by a nail or staple over loaded hit by lighting etc Similar abuses will damage the Connectors on the ends of the cable The connectors can also be damaged by excessive insertion and removal or flexing of the cable close to connector body While the 4 in 1 can identify a bad cable it cannot determine if the wire or the connec tors are

The 8 wires inside are grouped into 4 pairs of 2 wires each Not only must the 8 wires connect form end to end of the cable the paris in the cable must connect to specific pins of RJ 45 plugs on to the ends of cable ignoring the pairing as 14 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 cable fault is sometimes call a split pair or double split pair to detect this type of fault a more sophisticate tester capable of performing a NEXT test Near End Cross Talk must be used Both the Pair Master and LAN TDR can perform NEXT tests Notes Cross talk increases with the length of the cable A LAN system will tolerate a certain amount of cross talk A short cable 10ft or tess that is improperly paired may work just fine However longer cables paired in exactly the same way may not work This explains why an installer can make short jumper cables that work although they are improperly paired but when he installs RJ 45 s in exactly the same way on a longer cable the cable does not work 7 6 3 The 4 in 1 says my phone cable is bad but my phone works ok Most single line telephones only use 2 wires in a modular cable the modular cable which terminates in RJ 11connectors could have as may as 6 wires in it The unused wires may have faults which t
