INTERPRETING RESULTS
EXAMPLES OF WIRING ERRORS
INSTRUCTIONS FOR USE
LANSeeker™ 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.
3. The tester will power on immediately, indicating
a test in progress by quickly winking the pair
lights on both the main and remote; it will then
be followed by a combination of pair lights on —
this shows the test results.
4. Disconnect patch cable after 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.
To Test Installed Cable (Office jack to patch panel)
1. Remove remote unit from main unit by sliding
remote towards top of the main unit.
2. Attach one end of a one foot jumper cable to
remote and other end to wall jack.
3. Attach one end of the a second one-foot jumper
to main unit and the other end to the patch panel
jack.
4. The tester will power on immediately, indicating
a test in progress by quickly winking the pair
lights on both the main and remote; it will be
immediately followed by a combination of pair
lights on — this shows the test results.
5. Disconnect after 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 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
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.
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 connecte
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. 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. This most
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.
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.
ETHERNET UP-LINK CABLE EXAMPLE
1-2 and 3-6 swapped
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.
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.
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. This is from internal memory, so the cable
is not required to be connected when running debug.
The debug display begins with a short flash on the 1-2
pair to indicate that what follows is the result for the 1-2
pair test (or the “from”). If the pair was not open, a second
longer flash on one or more pair lights designates what
pair 1-2 is connected “to” at the remote end, or pairs
involved in a fault condition along with the fault lights. The
3-6, 4-5 and 7-8 pair lights each in turn begin with a short
flash followed by the results for that pair.
The individual pair results continue to be displayed until
the tone button is pressed again or two complete cycles of
all pairs is completed.
The remote unit does not display anything when in debug
mode.
often happens when the cable is terminated consistently
at both ends, but in the wrong order.
A dynamic 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.
