Network/Phone and USB Cable Test
ENGLISH
1. Connect one end of a network, phone or USB cable to the Network / Phone
(RJ45/12) or USB port on the Transmitter. Connect the other end of the network,
phone or USB cable to the Remote Terminator.
2. Switch the power button to the On position; it will perform a Quick Test by default.
Quick Test Mode
Quick Test mode quickly identifies the type of cable. If a test cable pin out matches
the pin out of a standard cable, the TC-NT3 Transmitter will indicate this by lighting
up the corresponding LED. The default mode on TC-NT3 is set to Quick Test mode.
You can also press the Test button 3 times to enter to Quick Test mode.
Note: Quick Test mode does not include shielded testing. If you would like to test a
shielded cable, please use Auto/Step or Learn mode.
Learn Mode
Learn mode allows the TC-NT3 to memorize and test large quantities of custom
shielded cables with any pin out or configuration. It displays PASS or FAIL.
1. Before using Learn mode, a known good cable is required.
2. Connect one end of a cable to the TC-NT3 Transmitter and the other end to the
Remote Terminator.
3. Power on the TC-NT3. Press the Mode button one time or until the Learn mode
LED is lit.
4. After the cable recording has completed, the Pass and ID LED will be lit. If the
Fail LED has lit, Learn mode has failed. Please press the Mode button again to
retest the cable until the Pass LED is lit.
5. If a new cable pin out is the same as the learned cable, the TC-NT3 will display
the Pass and ID LED.
6. If a new cable pin out is different from the learned cable, the TC-NT3 will display
the Fail and ID LED.
7. All stored pin outs in Learn mode will be erased after the TC-NT3 is power off.
