BATTERY LIFE

Low Battery - When the battery is below the level
required for the LanMaster 30 to operate properly, the
“SIGNAL” indicator blinks on and off while a test is being
conducted.

APPLICATIONS

Moves, Adds and Changes - Reduce risk of equipment
damage by identifying correct outlet for connecting
telephone and network devices.
Installation - Verify physical layer connectivity to the far­end equipment.
Trouble Calls - Reduce troubleshooting time by
ensuring the connection is correct and outlet is
functional. Prevent damage to sensitive test equipment
by identifying outlet type before running tests.
Telecom System Management - Locate expensive
unused analog phone circuits for reassignment or
termination.
Network Management - Identify Ethernet Link data rate
(10Mbps or 100Mbps) and support for auto-negotiation.

ETHERNET LINK SIGNAL OVERVIEW

Three different signals can be used to establish an
Ethernet Link: a Link Code Word, an NLP or an MLT-3
waveform. The Link Code Word is specific in both Link
speed and duplex mode. The NLP is specific in speed
(10Mbps) but ambiguous in duplex mode (half or full).
The MLT-3 waveform is also specific in speed
(100Mbps) but ambiguous in duplex mode. Duplex
modes for equipment that use NLP or MLT-3 signaling
must be carefully managed to ensure proper Link
operation.

BATTERY

The LanMaster 30 operates on one 9 volt alkaline

battery. Remove the battery cover
at the bottom of the unit and insert
the battery with the terminal
orientation as shown. Battery
polarity is marked on the back of
the battery cover and inside the
battery well for reference.

TECHNICAL OVERVIEW

The LanMaster 30 Outlet Identifier is a comprehen­sive signal detection, measurement and identification
device. The unit measures signals on every combination
of wire pairs in a four (RJ-11), six (RJ-12) or eight (RJ-

45) wire outlet or plug. The measurements are
compared to known signal parameters for telecommuni­cation and data communication equipment and reported
to the user by illumination of equipment-type LEDs. A
“SIGNAL” indicator is provided to warn when signals are
present at the outlet or plug that do not correspond to
known equipment parameters. A “NO LINK” indicator is
illuminated when no signals are detected on any of the
wires.

The LanMaster 30 conducts a three step test that is
completed in less than six seconds. The first test
measures voltages on all wire pairs and identifies an
Analog, PBX or ISDN telephone circuit. The second test
measures Standard (10baseT) and Fast (100baseTX)
Ethernet Link Signals and identifies the operating mode
of the far-end equipment. The third test transmits a
Token Ring voltage that causes the unit to be inserted in
to a ring and then measures the ring speed (4MHz or
16MHz).

OPERATION

Insert the LanMaster 30 plug end in to the RJ-45
jack of a wall outlet, or attach to a 4-wire, 6-wire or 8­wire patch cable with the RJ-45 coupler provided. Press
and hold the “TEST” button.

Telephone Circuit Identification

While the unit is conducting the telephone test, the
“TEL” indicator will blink on and off. During the first two

seconds of the test, each
combination (64 total) of two
wires are scanned for signals
and each voltage measure­ment is recorded. If
telephone line voltage is
detected on wire pair 4,5 and
no signals are present on any
other pair, the “TEL” indicator

is illuminated showing that an
analog phone line has been detected. If 24VDC or
48VDC is detected between wire pairs 3,6 and 4,5 (S/T
interface) or sealing current on pair 4,5 (U interface), the
“ISDN” indicator is illuminated showing that an ISDN
circuit has been identified. If appropriate voltage levels
are detected on one or more wire pairs, the “PBX”
indicator is illuminated showing that a PBX type switch
or a multiple line phone circuit has been detected.
NOTE: If voltages above expected levels are measured,
the “SIGNAL” indicator is lit showing that an unknown
and potentially damaging voltage is present. The user
should identify the equipment installed at the far-end
prior to connecting any devices to the outlet under test.

10baseT/100baseTX Link Identification

While the unit is conducting the 10baseT/100baseTX
Link test, the “10T” and “100T” indicators will blink on
and off. If an MLT-3 waveform is detected or a Link
Code Word is decoded for 100baseTX operation, the
“100T” indicator is illuminated showing a 100baseTX

connection. If a Normal Link Pulse (NLP) is detected or
a Link Code Word is decoded for 10baseT operation,

operation. The LanMaster 30 does not test 100baseT4.
The “SIGNAL” indicator will be illuminated if a Link Code
Word is detected that is invalid or contains a reported
Fault or the MLT-3 waveform frequency is incorrect.

While the unit is conducting the Token Ring Link

test the “TR” indicator will blink on and off. The Model 30

16MHz ring speed is measured. The “SIGNAL” indicator
is lit if the current is below the minimum value, indicating
an open wire, or the speed of the ring is not 4MHz or
16MHz.
