1. JDSU Detachable Remote Green Pair Lights Battery Cap Warning Do not attach to energized cables The LanRoamer may be damaged Caution Improperly crimped or un crimped plugs can damage the jacks on the LanRoamer Inspect plugs for proper termination and crimping before inserting into the tester Contacts should always be recessed into the plastic grooves of the plug Introduction The LanRoamer cable tester is a unique blend of a popular type of low end tester interface with an advanced microprocessor controller The most popular aspects of this type of tester are an indication at both ends that the cable has been tested no buttons to push to perform a test and a case that snaps together for storage The microprocessor brings the additional features of automatic power management split pair error detection direct indication of the type and location of faults and tone generation The patented split pair detection technique allows the LanRoamer to have these advanced features at a reasonable price Features Auto on and auto off when testing cables just plug both ends into tester Cable test results displayed on main unit and remote unit in less than 2 seconds after plugging in the cable Snap together case for easy storage and convenient patch cable testing Tone generator mode for use with tone tracers auto off Debug mode with from to and failures for each pair Bat2.

3. test The test repeats automatically every 2 3 seconds if the cable has only open and passing pairs and repeats every 4 seconds if there are failures Application Hints The jumper cables must be short compared to the cable run for accurate split pair indication no more than 10 of the total run length To Test Coax Requires optional RJ45 to coax adapter 1 Plug the RJ45 to F coax adapters into the remote and main units 2 Attach cable to be tested to F connectors 3 The tester will power on if it senses the cable If not the cable is open The coax adapter is connected to the 1 2 pair and will be on steady if good or blink the 1 2 and short lights if shorted To Place Tone on a Cable 1 Press and release the TONE button The light immediately above the button will start flashing 2 Connect cable to be traced to main unit For best signal do not connect remote Due to the shielding effect of twisted pairs the strongest signal is obtained by connecting only one wire in a cable to the tone source 3 To turn tone off press the TONE button a second time The tone will turn off automatically after 3 hours Interpreting Results Definition of Errors See Examples of Wiring Errors The four fault lights are discussed below in order of severity The severity has to do with the ability of the type of error to mask lower severity errors For example if there is a short in the cable miswires reversals
4. amic or AC test is required to detect this type of error If the only error is a split pair error the cable has correct continuity If cross talk is not a concern as in flat satin cable the cable is good if the only error is the split pair error Examples of Wiring Errors SPLIT PAIR 1 not twisted with 2 3 not twisted with 6 Main Unit Results The main unit indicates the beginning of a test by flashing the pair lights in sequence top to bottom The cable is then tested and the results displayed as follows Pair light off Pair is open Depending on the wiring standard this may be correct Pair light on Pair is wired correctly Pair light is flashing One or more errors were detected for this pair as indicated by flashing error lights If there are no flashing lights the results are displayed for 2 seconds If there was an error the results are displayed for twice as long Remote Unit Results The remote unit indicates the beginning of a test by flashing the pair lights quickly the order or number of lights flashed depends on the cable being tested The cable is then tested and the results displayed as follows Pair light off Pair is open or has a fault Depending on the wiring standard this may be correct Pair light on Pair is wired correctly If there are no errors the results are displayed for 2 seconds 10 If there was an error the results are displayed for twi
5. and split pairs cannot be detected for the pairs involved in the short fault Multiple faults on multiple pairs can be better understood by using the debug mode to examine the errors one pair at a time Short The pair has a low resistance connection from one wire of the pair to the other wire of the pair or to any other wire in the cable or the shield A single flashing pair light and the short light indicate a short within the pair Multiple flashing pair lights and only the short light indicate shorts between the pairs involved Miswire A wire or both wires of a pair are not connected to the correct pins at the other end of the cable Debugs from to format is very helpful in visualizing what the specific miswire is Reverse A reverse is a special case of a miswire in which the pair is wired to the correct pair of pins or to another designated pair of pins but the two leads are reversed Split Pair A split pair is an error in the twisting of the wires together within the cable The cables generally are made up of eight wires twisted together in 4 pairs These 4 pairs are designated as pairs by the wiring standards and are intended to carry a signal and it s return 182 38 6 48 5 and 7 amp 8 are the pairs designated by T568A B A cable can be wired with correct continuity but not with correct pairing This most often happens when the cable is terminated consistently at both ends but in the wrong order A dyn
