Introduction:
The LAN/USB Cable Tester is designed to easily read the correct cable pin out
configuration。The cables include the USB (A/A), USB (A/B)、BNC 10-Base-T, 100Base-TX、
1000Base-TX, Token Ring, AT&T 258A、Coaxial、EIA/TIA 568A/B and RJ11/RJ12 modular cables.
Just connect the cable both sides with CT-168. If you want to test cable installed far away, either on
patch panel or wall plate, simply use the Remote terminator. When use the CT-168 tests RJ11/RJ12
cable, please use the appropriate, adaptors and follow the procedure below to use it very carefully.
Operation:
Using the Master tester, plug one end of the tested cable (RJ45/USB) to the marked with “TX”,
and another end of tested cable to the marked with “RX”, or Remote terminator RJ45/USB
connector.
Turn the power switch to “TEST”. In the step by step mode, the LED for pin 1 with light up. With
each press of the “TEST” button, the LED will scroll in sequence. In the “AUTO” scan mode, the
upper row of LEDs will begin to scroll in sequence from pin 1 to pin 8 and ground.
Reading the result of the LED display tells the correct status of the tested cable. If you read out
the incorrect LED display, the tested cable is bad in short open, reversed, miss-wired or crossed
over.
If the battery is low on power, the LEDs will be dimmed or no light, and the test result will be
incorrect.
Remote:
Using the master tester, plug one end of tested cable to the marked with “TX” jack and another
end on the receiving of Remote terminator. Turn the power switch to Auto mode and use the
adaptor cable, if the cable terminates into a patch panel or wall plate.
The LED one the Remote terminator will begin to scroll, in relation to the master tester indicating
the cable’s pin out.
