NETWORK CABLE TESTER OPERATION
Note: Make sure the battery power is sufcient. Insufcient battery power will lead to
dimmed LEDs and potentially incorrect results.
Base-T Test
• Plug one end of the cable to be tested into the transmitting RJ45 jack on the
master unit marked with a ‘ ‘ and the other end of the cable into the remaining
receiving RJ45 jack.
• Slide power switch on. The upper row of LEDs will start to scan in sequence if the
Auto/Manual button is set on “Auto” mode. The LED for pin 1 will light up if the
button is in “Manual” mode.
• Switch from Auto to Manual scanning mode by pressing the Auto/Manual button on
the side of the master-testing unit.
• Once both ends of the cable are plugged in correctly, the second row of LEDs will
illuminate according to the corresponding LEDs in the top row.
• Read the results of the LED display for the pin conguration status of the tested
cable. If you fail to read the results the rst time in Auto mode, you may wait for the
second LED scan, or simply switch to Manual mode for pin by pin testing.
• In Manual mode, pressing the “Test” button will advance testing to the next pin.
RJ11 Modular Cable Test
• Plug one end of the cable to be tested into the transmitting RJ45 jack on the
master unit marked with a ‘ ‘ and the other end of the cable into the remaining
receiving RJ45 jack.
• The method of testing is similar to that for RJ45 except only the middle 4 pins are
used.
Coaxial Cable Test
• Plug the two attached BNC adapter cables into both RJ45 jacks. Then connect the
cable to be tested to each end of the BNC adapter cables.
• For the remaining testing procedures, please refer to 10Base-T Test steps 2 to 5
• Slide the power switch to on.
• As Coaxial cable has only two wires, we suggest you read the result of the LED
scan using Manual mode.
• The centre pin of a BNC cable should be read on LED 2.
Remote Cable Test
• Plug one end of the cable to be tested to the transmitting RJ45 jack on the master
unit marked with a ‘ ‘.
• Plug the other end into the remote terminator. If the cable to be tested is installed
in a patch panel or wall plate, you may use the included patch cable to solve the
connector gender problem.
• Set the Auto/Manual switch to Auto mode for one-person testing.
• Read the test results from the LED display on the remote terminator.
Note: The LED display on the remote unit will scan in sequence corresponding to the
transmitting end of the master unit.
Caution: Operating the tester in live circuits may damage the tester.
