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 comprehen-
sive 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 telecommuni-
cation 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 8-
wire 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 measure-
ment 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,
the “10T” indicator is
illuminated. If a Link Code
Word is decoded for 10/100
auto-negotiation, both the
“10T” and “100T” indicators
are illuminated showing that
the far end equipment is
capable of auto-negotiating
to either the 10baseT or
100baseTX mode of
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
transmits the standard Token
Ring phantom voltage
between wire pairs 3,6 and
4,5. If the measured current
is within the correct range,
the voltage is maintained to
allow the unit to be inserted
into the ring. Once inserted in
the ring, the “TR” indicator is
illuminated if a 4MHz or
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.
No Link No Link No Link No Link No Link
When no signals are detected during any of the three
previous tests, the “NO LINK” indicator is illuminated.
Total time to complete all tests is less than six seconds.
