Product Overview

Product Usage Instructions

Power On/Off

  1. Transmitter
    Switch the key upwards The device powers on, with the line tracing indicator light illuminated continuously:
    Switch the key downwards  The device powers on, with the pairing indicator light illuminated continuously.
    Switch the key to the middle position The device powers off.

  2. Receiver
    Switch the key upwards The device powers on with illumination.
    Switch the key to the midden position The device powers on.
    Switch the key downwards The device powers of.

Cable scan Function

Efficiently and quickly locate the target cable from numerous messy cables, complex circuits, and switches.

  1. Insert the target cable into the RJ45 or RJ11 port at the top of the transmitter. Turn the transmitter switch to the tracing position, and the cable scan indicator light turns green
  2. Turn on the receiver, adjust the sensitivity knob to adjust the sensitivity, and use the probe to approach the target cable for detection. When a signal is received, the receiver will emit a “beep-beep-beep” sound, and the sequence light will turn red (the stronger the signal, the more lights will be illuminated), thus locating the target cable.

Product Highlights:

During cable scan, inserting the target cable into the receiver’s RJ45 port allows for direct pairing without operating the main unit.

Cable scan Tips:
Initially set the sensitivity to the maximum to locate the approximate range, then reduce the sensitivity for precise positioning of the target cable.

Cable Continuity
Used to detect the wire sequence, continuity, discontinuity, crossover, short circuit, and other conditions of network cables/telephone cable.

  1. Insert one end of the cable to be tested into the RJ45 port of the transmitter and the other end into the RJ45 port of the receiver.

  2. Turn the transmitter switch to the pairing position. The line indicator light turns green, and the test results are as follows:

  3. Continuity: The Continuity lights of the transmitter and receiver correspondingly flash green one by one
    Transmitter: 1-2-3-4-5-6-7-8 Receiver: 1-2-3-4-5-6-7-8

  4. Crossover: Taking 2 and 5 as an example, when the transmitter’s line indicator light is on 2, the receiver’s light is on 5. When the transmitter’s light s on 5, the receiver’s light is on 2
    Transmitter: 1-2-3-4-5-6-7-8 Receiver: 1-5-3-4-2-6-7-8

  5. Discontinuity: Taking 2 as an example, the indicator light for wire 2 does not illuminate, while the other indicator lights flash normally.
    Transmitter: 1-X-3-4-5-6-7-8
    Receiver: 1-X-3-4-5-6-7-8

  6. Short Circuit: Taking 2 and 5 as an example, when the transmitter’s line indicator light is on 2 or 5, the receiver’s 2 and 5 lights are on simultaneously but with dim brightness.
    Transmitter: 1-2-3-4-5-6-7-8
    Receiver: 1-2-3-4-5-6-7-8
    Transmitter: 1-2-3-4-5-6-7-8
    Receiver: 1-2-3-4-5-6-7-8

Note: In continuity mode of the transmitter, a short press of the switch button can switch between fast pairing and slow pairing.

Open/Short Circuit Testing

In transmitter’s pairing mode, long press the switch button to enter the open/short circuit testing mode. The pairing indicator light (green light) flashes.

Insert the alligator clip into the RJ11 port of the transmitter, clamp the two ends of the cable to be tested with the alligator clip. The test results are as follows:

  1. If the cable scan indicator light is not illuminated, then the cable being tested is open.
  2. If the cable scan light is illuminated in red, then the cable being tested is short-circuited.

Battery Polarity Testing (DC3~60V)

In transmitter’s tracing mode, long press the switch button to enter the battery polarity testing mode. The tracing indicator light (green light) flashes.

Insert the alligator clip into the RJ11 port of the transmitter, and use the red and black alligator clips to contact the two ends of the battery respectively.
The test results are as follows:

  1. If the pairing indicator light is illuminated in red, then the red clip is the positive pole.
  2. If the pairing indicator light is illuminated in green, then the red clip is the negative pole.

POE Testing

Connect the PoE switch and the receiver’s RJ45 port with a network cable.
The receiver’s pairing indicator light flashes, indicating that power is supplied to this core.

  1. If lights 12 or 36 flash, it indicates that cores 12 or 36 are powered, and the power supply method is end-spanning.
  2. If lights 45 or 78 flash, it indicates that cores 45 or 78 are powered, and the power supply method is mid spanning.
  3. If lights 12 or 36 flash along with lights 45 or 78, it indicates that the PoE switch supplies power in 8 cores.
  4. If lights 1-8 on the receiver do not flash, it indicates that the switch is not a PoE switch or is not powered.

NCV

In receiver’s tracing mode, long press the switch button for 2 seconds to enter the NCV mode. The NCV indicator light turns green.

When AC power is detected, the buzzer will emit a “beep-beep-beep” sound, and the sequence indicator light will illuminate in red. The stronger the signal, the more lights will illuminate.

Light Function

Turn the switch of the receiver to the upper position to turn on the illumination light. When the illumination light is turned on, other functions remain unchanged.

Power Indicator

Transmitter:
The tracing indicator light alternates between red and green flashing, indicating low battery. Please replace the battery in time.

Receiver:
The tracing indicator light flashes continuously, indicating low battery. Please replace the battery in  time.
