3.1 10Base-T Test
1. Plug one end of the tested cable into the transmitting RJ45 jack on the master unit
marked with a '1' and the other end of the cable into the receiving RJ45 jack.
2. 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.
3. Switch back and forth from Auto or Manual scanning mode by pressing the
Auto/Manual button on the side of the master testing unit.

4. Once both ends of the cable are plugged in properly, the second row of LEDs will
illuminate according to the corresponding LEDs in the top row.
5. Read the results of the LED display for the pin configuration status of the tested
cable. If you fail to read the results the first 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 square "Test" button will advance testing to the next
pin.
Note: Make sure the battery power is sufficient. Insufficient battery
power will lead to dimmed LEDs and incorrect results.
3.2 RJ11 Modular Cable Test
1. Please follow directions for the UTP/STP Cable Test and refer to the diagram
below for the correct LED pin out display
3.3 Coaxial Cable Test
1. Plug the two included BNC adapter cables on both RJ45 jacks.
2. Then connect the BNC cable to each end of the BNC adapter cables
3. 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.
4. Switch back and forth from Auto or Manual scanning mode by pressing the
Auto/Manual button on the side of the master testing unit.
5. Once both ends of the cable are plugged in properly, the second row of LEDs will
illuminate according to the corresponding LEDs in the top row.
6. Read the results of the LED display for the pin configuration status of the tested
cable. If you fail to read the results the first time in Auto mode, you may wait for
the second LED scan, or simply switch to Manual mode for pin by pin testing. In

5
Manual mode, pressing the square "Test" button will advance testing to the next
pin.
Note: The center pin of BNC should be read on LED 2. Please refer to the diagram
below
2. As Coaxial cable has only two wires, we suggest you read
the result of the LED scan using Manual mode.
3.4 Remote Test
1. Plug one end of the tested cable to the transmitting RJ45 jack on the master unit
marked with a '1' and plug the other end into the remote terminator. If the tested cable
is installed in a patch panel or wall plate, you may use the included patch cable to
solve the connector gender problem. Please refer to Diagrams below.
2. Now, set the Auto/Manual switch to Auto mode for one-person testing.
3. Read the test results from the LED display on remote terminator.
Note: The LED display on the remote unit will scan in sequence corresponding to the
transmitting end of the master unit.
