C2G Network Cable Tester-Pro User Manual
Network Cable Tester-Pro Model No. 251451/Pro
The Network Cable Tester-Pro is designed to test quickly, the most popular cable wiring that uses twisted
pairs, such as TIA568A/568B,Token Ring and 10/100BASE-T (STP/UTP) . It will automatically test the
cables once they are plugged into the master and remote unit and the power turned on. It will also test
coaxial cables. It can test CAT 5 & 6 cables for continuity, miss wiring, reversed and ground by the
following test procedures.

Continuity test :
Step 1. Install the 9V alkaline battery in the rear battery compartment.
Step 2. Plug both ends of the RJ-45 or BNC cable into the sockets of the tester. One in the Master unit and
the other into the remote unit
Step 3. After the cable is plugged into the tester, turn on the power and the unit will continuously auto
scan the wires. The LED's on the tester will turn either green, red or no LED. Any LED'S not green
show a fault on the twisted pair. Pressing the Ground button will tell you if any wires are ground .
A green light on the BNC cable means the cable is good while a red light means the cable is bad.
RJ-45 Fault Status Red : Short, Reversed or Miss wire
RJ-45 Fault Status No Light : Open
BNC Fault Status Red Light : Short
Any LED's displaying red or no lights mean the cable is miss-wired, open or shorted or
reversed. Check the cable connections again and start the tests again from Step 2.

the other into the remote unit
Step 3. After the cable is plugged into the tester, the LED's on the tester will turn either green, red or no
light. Any LED'S not green show a fault on the twisted pair. A green light on the BNC cable means
the cable is good while a no light means the cable is bad.
RJ-45 Fault Status Red : Short, Reversed or Miss wire
RJ-45 Fault Status No Light : Open
BNC Fault Status No Light : Short Open
Any LED's displaying red or no lights mean the cable is miss-wired, open or shorted or reversed.
Check the cable connections again and start the tests from Step 2.
