OPERATING INSTRUCTIONS
MODEL:
GMC-3000
Crimp-n-Test
SAFETY WARNINGS
This instruction manual contains warnings and safety rules which
must be observed by the user to ensure safe operation of the
instrument and retain it in safe condition. Therefore, read through
these operating instructions before using the instrument.
!

WARNING – Do NoT uSE oN lIvE CIRCuITS
Note: Although the GMC-3000 is equipped with 8 position modular
plug jacks, cables with smaller 6 position and 4 position connectors
may also be tested. The user should be aware that the use of
smaller connectors will reduce the total number of jack insertions
over the life of the product.
TESTING PATCH CABlES
1. Connect the main unit to one end of the cable to be tested.
2. Connect Remote unit to plug at far end of cable.
3. Push the TEST button to perform test.
4. Read LEDs to determine cable wiring status.
TESTING INSTAllED CABlES
1. Using the jumper cable, connect the remote unit to the wall jack
or patch panel port to be tested.
2. Using the second jumper cable, connect the main unit to the
other wall jack or patch panel port to be tested.
3. Push the TEST button to perform test.
4. Read status of LEDs to determine cable wiring status.
TEST RESulTS
PASS Indicators
Shield
Standard Wiring
Green SHIELD LED indicates the
Shield on the cable is correctly
and continuously wired through
the modular plug termination.
Four green LEDs on pairs 1-2,
3-6, 4-5, and 7-8.
All four pairs are terminated
correctly.
FAIl INDICAToRS
A flashing LED indicates that this wire pair has a fault. A flashing
LED in the FAIL section will indicate which fault was detected.
Multiple flashing LEDs indicate multiple pairs and/or multiple faults.
Best practice is to correct cable faults until cable is verified as
correct with appropriate green LEDs.
• SHoRT – A short circuit condition exists.
• MISWIRE – Indicates the improper assignment of individual wire
pairs to pins for the wiring schemes tested. Tester checks T568A,
T568B, 10Base-T, and Token Ring configurations.
• REvERSAl – Reverse wiring means the pin for
one wire in a pair is connected to the opposite
pin for the pair in the remote jack.
• SPlIT PAIRS – Split pairs occur
when the tip (positive conductor)
and ring (negative conductor) of
two twisted pairs are interchanged.
Note: The GMC-3000 will check a
fault condition in the above
descending order before detecting
other fault conditions. The detection
and indication of the presence of
a fault is handled on a “one-per-test”
basis. Once a fault is corrected, it
is recommended the cable be
tested again for other faults.
DEBuG MoDE
The DEBUG mode identifies which cable pairs have a wiring fault.
It cycles through pairs displaying a test result for one pair at a
time. From the series of LED indications, the failed pair and
fault can be identified. In Debug mode, a short flash on PAIR
LED is the pair under test. A long flash on PAIR LEDs is
destination of test.
To DEBUG:
1. Press and hold TEST button until all LEDs light, then release.
2. The pair identification LEDs and the FAIL LEDs work together in
series to identify which pair is incorrect.
3. If a series of two green LEDs light for a pair then that pair is
wired correctly.
4. A green pair LED followed by a red LED in the FAIL section
identifies which pair is incorrect and identifies the fault.
5. DEBUG cycles through the pairs twice before automatically
shutting off.
6. Pushing and quickly releasing the TEST button also turns
tester off.
DEBuG Example #1 The Cable Fault is a SHORT on Pair 3-6, the
DEBUG mode LED series will be as follows:
• Pair 1-2 will flash green-green as a good pair
• Pair 3-6 will flash green on the pair LED followed by a red on the
SHORT LED
• Pair 4-5 will flash green-green as a good pair
• Pair 7-8 will flash green-green as a good pair

sequences on pair 1-2 and interpretation of various fault conditions

BATTERY REPlACEMENT
1. Remove screws from back of main handle using a #1 Philips
screwdriver. Carefully open tester.
2. Remove old batteries.
3. Install a new 6 volt A544 1/2AA size battery or 4LR44 Button
cell batteries.
4. Close tester and replace screws. Do not over tighten.

ADvERTENCIA – No SE DEBE uSAR EN CIRCuIToS
ENERGIzADoS
Nota: Aunque el GMC-3000 está equipado con tomas de enchufe
modulares de 8 posiciones, también pueden probarse conectores más
pequeños de 6 posiciones y 4 posiciones. El usuario debe tener presente
que el empleo de conectores pequeños reducirá la cantidad total de
inserciones de la toma durante la vida útil del producto.
PARA PRuEBAS CABlES DE PARCHE
1. Conecte la unidad principal a un extremo del cable a probar.
2. Conecte la unidad remota al enchufe del extremo alejado del cable.
3. Pulse el botón TEST (prueba) para realizar la prueba.
4. Lea las luces indicadoras (LED) para determinar el estado del
cableado.
PARA PRuEBAS CABlES INSTAlADoS
1. Usando el cable puente conecte la unidad remota a la toma de
pared o puerto de panel de parche a probar.
2. Usando el segundo cable puente conecte la unidad principal a la
otra toma de pared o puerto de panel de parche a probar.
3. Pulse el botón TEST (prueba) para realizar la prueba.
4. Lea las luces indicadoras (LED) de estado para determinar cómo está
el cableado.
RESulTADoS DE PRuEBA
Indicadores de que PASA la prueba
Blindaje
Estándar Remoto
La luz indicadora verde (LED)
SHIELD (blindaje) indica que el
blindaje del cable está cableado
correcta y continuamente a través de
la terminación del enchufe modular.
Cuatro luces verdes indicadoras
(LED) en pares 1-2, 3-6, 4-5 y 7-8.
Los cuatro pares tienen
terminaciones correctas.
INDICADoRES DE FAllA
Una luz indicadora (LED) destellante indica que este par de
cables tiene una falla. Una luz indicadora destellante en la sección
FAIL (FALLA) indica la avería que se detectó. Si hay varias luces
indicadoras destellantes quiere decir que hay varios pares y/o fallas
diversas. Lo mejor es corregir las fallas de cables hasta que se
verifique que los cables están correctos con las luces indicadoras
verdes (LED) adecuadas.
• CoRToCIRCuITo – Existe un cortocircuito.
• CABlEADo INCoRRECTo – Indica la asignación indebida de pares de
cables individuales a patillas para los esquemas de cableado probados.
El probador revisa configuraciones T568A, T568B, 10Base-T y Token
Ring.
• INvERSIóN – Un câblage inversé signifie que la
broche pour un fil dans une paire est raccordée à la
broche opposée pour cette paire dans la prise distante.
• PARES DIvIDIDoS – Los pares divididos ocurren
cuando se intercambia la punta (conductor positivo)
y el aro (conductor negativo) de dos pares trenzados.
