PAIRMASTER OVERVIEW
The Triplett PairMaster is an essential test tool for the LAN
cable and network installer, maintainer, and technician. It ana-
lyzes the LAN cable for faults, performs network mapping, and
checks Near End Crosstalk (NEXT). Its Auto Power Off feature
extends battery life and its built-in Overload protection prevents
damage from crossed phone lines.
Comprised of a Main Unit and as many as 16 Remotes (2
included, 14 optional), the PairMaster is adept at testing patch
cables or installed wiring, with distances ranging from 0 to
400ft.
Its fault detection capabilities includes a comprehensive test
of the cable’s conductors, identifying any Opens, Shorts, or
Miswiring. The results are displayed by simple PASS/FAIL
indicators. If a fault is detected, a digital display shows an error
code that identifies the specific failure.
A LAN network is easily mapped by using the Remotes, each
with its unique signature. Figure 1 illustrates the mapping pro-
cess, with the Main Unit at the Switch or Hub, and the Remotes
placed throughout the facility at the cable endpoints. The Main
Unit identifies the connected Remote on its large digital display.
The PairMaster goes beyond simple continuity testing of the
cable, employing a high speed NEXT test to identify cable con-
struction problems that could corrupt the digital data.
A rugged and reliable industry workhorse, the PairMaster is the
choice of LAN and IT professionals.

FEATURES
1) OVERVOLTAGE INDICATOR LED
The LED on the Remote Identifier will light up whenever Telco
voltages are detected on the cable under test.
Example: Connecting the remote to a cable that is energized
by a 48 VDC Central Office Battery (a telephone line) will cause
the OVERVOLTAGE INDICATOR LED to light up. The LED will
remain ON until the overvoltage condition is corrected or the
Remote Identifier is removed from the cable.
2) REMOTE IDENTIFIER
The Remote Identifier is a small module that is connected to
the far end of the cable. Each Identifier properly terminates the
cable. It also contains circuitry to allow the PairMaster to verify
proper wiring within the cable. Sixteen unique remote units,
numbered from 1 to 16, can be used to identify a particular
cable in a bundle.

3) RJ-45 MODULAR JACK
This jack is a standard 8-pin modular jack for connecting UTP
(Unshielded Twisted Pair) cable to the PairMaster. The jack is
keyed so that it can accept either keyed or non-keyed RJ-45
plugs.
4) DIGITAL DISPLAY
Under PASS conditions, the display shows the number of the
Remote Identifier attached to the cable. Under FAIL conditions
the appropriate Fault Code is displayed (see page 11).
5) PASS/FAIL LEDs
Each pair in the cable (Conductors 1/2, 3/6, 4/5, 7/8) have one
green LED (PASS) and one red LED (FAIL). The LEDs light up,
based on the test results of each pair.
6) PUSH-TO-TEST BUTTON (PTT)
Press this button to turn on the PairMaster and start a new test.

OPERATING INSTRUCTIONS
Connect each Remote Identifier into the terminal jack of an
office. Observe the OVERVOLTAGE INDICATOR LED on the
remote. If the LED is on, Telco voltage is present. Remove the
Remote Identifier and investigate the problem. The PairMaster
is not intended for use on telephone systems.
*** WARNING *** Never connect any LAN device to an
overvoltage line (telephone line). Damage to the hub or to the
terminal may result.
Connect the RJ-45 patch cable to the wiring hub ‘s patch panel.
Plug the other end of the patch cable into the PairMaster’s
RJ-45 jack.
** NOTE ** Using the patch cable and the in-line couplers is
recommended to reduce wear on the PairMaster’s RJ-45 jack.
Press the PUSH-TO-TEST (PTT) button to begin testing the
cable for proper wiring. Observe the digital display. Upon press-
ing the PTT button, several different displays may be shown.
Under normal conditions the display will read “--“, indicating
that the PairMaster is testing the cable.
If “Lb “ is displayed, the battery is low and should be replaced
before testing is continued.
If “OL” flashes in the display, an overvoltage is detected on the
connected cable. Remove the cable immediately and correct the
overvoltage problem before continuing. Following an overvolt-
age indication, wait for at least 15 seconds before pressing the
PTT button again. The PairMaster is in ‘overvoltage timeout
mode’ and will not reactivate until the time-out period has
expired.
