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.
Features • uto-on and auto-off when testing cables, A just plug both ends into tester! • able test results displayed on main unit C 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 • Battery low indicator • Tests for shorts, opens, miswires, reversals and split pairs
Description The main unit has four green pair lights, a green shield light, four red fault lights, a red battery low light and a green tone light. The remote unit has four amber pair lights. When a connection from the main unit to the remote is sensed, testing begins automatically. On the main unit, the lights for each pair will either be ON, OFF or FLASHING. An ON light indicates a good pair, an OFF light indicates an open pair and a FLASHING light indicates a bad pair.
Instructions for Use LanRoamer™ powers off automatically after 5 minutes of continuously testing a cable. Disconnecting the cable restores normal function. Be sure to install a battery if using for the first time—see battery installation. To Test a Patch Cable 1) Plug one end of patch cable into main unit. 2) Plug other end of cable into remote unit.
To Test Installed Cable (Office jack to patch panel) 1) R emove remote unit from main unit by sliding remote towards top of the main unit. 2) Attach one end of supplied one foot jumper cable to remote and other end to wall jack. 3) Attach one end of the second supplied onefoot jumper to main unit and the other end to the patch panel jack.
To Test Coax (Requires optional RJ45-to-coax adapter) 1) P lug 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) P ress and release the TONE button. The light immediately above the button will start flashing.
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 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.
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. 1 & 2, 3 & 6, 4 & 5 and 7 & 8 are the pairs designated by T568A/B. A cable can be wired with correct continuity, but not with correct pairing.

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. If the lights for the pairs expected are on, the cable is good. Debug Mode – (See “Ethernet Up-Link Cable Example”) The debug mode is provided to allow diagnosis of faults, especially when there are multiple errors on multiple pairs. To enter the debug mode, press and hold the tone button until all lights on the main unit light (lamp test). Once the lamp test is complete, debug displays the results of the last cable test.

Battery Replacement When the battery low light is on while generating tone or testing cables, the battery should be replaced as soon as practical. The cable testing results will become unreliable when the battery reaches about 4.5 volts. To replace battery: 1) R emove rubber battery cap by peeling back a corner until it pops off. 2) P ull battery out of cavity and remove battery snap. 3) C onnect a new Alkaline 9 volt battery to battery snaps. 4) S lide battery into cavity and snap cap in place.
