Interface and Function Introduction

Emitter Interfaces and functions:

Cable tracer (Receiver) Interfaces and functions：

Note: Receiver port continuity detection only supports the local end and does not support the remote end. The emitter can support near-end, middle-end, and far-end port detection.

Product Usage Instructions

Power On/Off
The device does not come with batteries. The Emitter uses 3 AA batteries, and the receiver uses 2 AA batteries. Press and hold the power button for 2 seconds to turn the device on or off. Note: If the Emitter’s screen flickers or displays unclear information, or if the battery icon is empty, replace the batteries. If the receiver’s 1-8 signal lights keep flashing after powering on, replace the batteries.

Setting Backlight Time and Auto Shutdown
In the power-on state, press the settings key to enable and switch between auto shutdown or backlight timeout options. Use the left and right keys to set the time. Auto shutdown can be set from 0 to 240 minutes (0 means auto shutdown is off). Backlight timeout can be set from 0 to 60 seconds (0 means the backlight stays on).
Press the confirm key to save settings. Press the menu key to exit without saving.

Cable Tracing
Connect the network or telephone cable to the “Wire Mapping/Continuity Test/Cable Tracing” port on the Emitter. Press the menu key to switch to the cable tracing function (default on startup). The receiver can be used for cable tracing.
Adjust the sensitivity knob on the receiver. The closer the receiver’s probe is to the cable, the stronger the signal and the louder the sound.
Press and hold the “SNCV” key on the receiver to enter or exit silent mode.
Use the left and right keys to switch between UTP and STP modes. UTP is for unshielded network cables, and STP is for shielded network cables.

Quickly verify the tracking result: After finding the cable, connect the network cable to the wire receiver “UTP” port for pair line detection. For example, when the “Straight/Cross/Other” lights up, indicates the verification of the matching cable.

Note: The UTP port of the emitter and receiver can max 60V withstand voltage, and the wire can be traced directly in connection with the PoE switch.

Power Detection Function

Power Detection
Turn on the receiver. Both the “SCAN” and “NCV” indicators will light up, allowing simultaneous cable tracing and power detection.
When the probe detects nearby AC voltage, the power detection indicator on the receiver will flash and emit a beeping alarm. The 1-5 indicators on the panel will flash to indicate the current power detection signal strength. Different signal strengths will result in different beeping frequencies and light flashing frequencies.

SNCV Enhanced Power Detection
When the receiver is in “SCAN + NCV”, press the “SNCV/Silent” key to increase power detection sensitivity. This can be used to trace plastic water pipes or high-voltage wires inside walls (not effective for iron pipes).

Note: This function only works in ” SCAN + NCV ” mode.

Live/Neutral Wire Detection Mode
Touch the receiver’s probe to the live/neutral wires in the electrical box or the live/neutral holes in wall sockets or power strips. The indicator lights and beeping alarm will help distinguish between live and neutral wires.

• Live Wire: The indicator flashes quickly, and the beep is rapid.
• Neutral Wire: The indicator does not light up or flashes slowly, with no beep or a slow beep.

UTP/Continuity Test

UTP test
Connect the network or telephone cable to the “UTP/Continuity Test/Cable Tracing” port on the Emitter, and the other end to the UTP port on the receiver (the receiver must be powered on).
On the Emitter, press the menu key to switch to the “CONT” (continuity) function mode to perform the wire mapping test.
The 1-8 and S sequence indicators on the screen will display the network cable sequence.

• 1Gbps/100Mbps: Indicates whether the cable can be used for 1000M or 100M Ethernet networks. A straight-through connection will be displayed with a “|”, and a crossed connection will be displayed with a jumping indicator. The receiver can also display this information.
• 255: Receiver number, which can be customized.

The receiver’s network cable type indicator can quickly determine if the cable is normal. If it shows “Straight-Through” or “Crossed”, the cable is normal. When testing the sequence, a “beep” indicates a connected pair, and a “buzz” indicates a shorted pair (all shorted pairs will light up simultaneously).

After the 8 indicators finish flashing, the receiver will beep to indicate the cable type: one beep for straight-through, two beeps for crossed, and three beeps for other or incorrect connections.

Continuity Test
The continuity test checks the connection of the RJ45 connector or the cable within 10cm of the port (note: the receiver tests up to 1 meter).
In UTP mode, connect the network cable to the “UTP/Continuity Test/Cable Tracing” port on the Emitter. The “1-8, S” indicators will show the continuity test results. If the indicators light up normally, the RJ45 connector is properly crimped. If an indicator does not light up, the corresponding pin is not properly crimped.

The continuity test on the receiver: Turn on the receiver, press Port continuity, and connect the network cable to the receiver’s “UTP” port. The “1-8, S” indicator light being on indicates that the crystal head is wired normally. The indicator light being off means that the wiring at the corresponding PIN is abnormal.

Length Measurement
Measure the length of open/short-circuited network cables from 1 to 600 meters. Note that the other end of the cable should not be connected to any device or powered on. Insert the cable into the “Length/Port Flashing” port on the left side of the Emitter.
On the Emitter, press the menu key to switch to the “Length” function mode, then press the confirm key to start the length measurement.

After the test completes, the results for each twisted pair will display on the screen.

Port Flashing
Connect the network cable to the “Port Flashing” port on the Emitter, and the other end to a switch or router.
On the Emitter, press the menu key to switch to the “Flash” function mode. The device will automatically start the test.
The device will send a flashing signal. If the connection is normal, the switch port icon on the screen will flash at a certain frequency. If the connection is not normal (e.g., the cable is not properly connected), the switch port will not change. The switch or router port will flash at a fixed frequency, making it easy to identify the target port and avoid unplugging the wrong cable.

Port Rate Detection: The port rate is automatically detected simultaneously when the port flashes.

The possible reasons for abnormal results are as follows: 1. The wrong port was connected to the Emitter. 2. The network cable is faulty or not properly connected. 3. The ports of the switch or router are faulty. 4. The instrument is faulty.

PoE Detection
The PoE function is used to detect the PoE power supply protocol, power supply pairs, voltage, and real-time power when connected to a PD load device. It supports IEEE802.3bt/at/af and non-standard protocols.
Connect the network cable to the “PoE Input” port on the Emitter, and the other end to a PoE switch or power supply.

On the Emitter, press the menu key to switch to the “PoE” function mode. The device will automatically start the test.

PD electric detection: The PD interface at the bottom of the receiver is connected to the POE switch or the power supply device, and the light indicates that there is POE voltage output. 1236,4578 Two indicator lights indicate that the cable pair is powered. When both indicators are on, both pairs are powered.

Optical Power Meter *（optional）
Connect the fiber optic cable to the “OPM” port on the Emitter, and the other end to an optical terminal or fiber optic transceiver.

Troubleshooting

• Device shows unclear information or flickers (Emitter): Replace the Emitter batteries (battery icon empty or screen unclear/flickering).
• Receiver signal lights keep flashing after powering on: Replace the receiver batteries.
• Port flashing does not change for the expected switch/router port: Possible causes include the wrong port connected to the Emitter, a faulty or improperly connected cable, faulty switch/router ports, or an instrument fault.
• Continuity/RJ45 pin issues (UTP continuity test): If an indicator does not light for a specific pin, that corresponding pin is not properly crimped. (Receiver continuity checks support the local end up to 1m; it does not support the remote end.)
• Silent mode not taking effect during cable tracing: Silent mode (SNCV) is effective only in SCAN + NCV mode.
• SNCV enhanced power detection not working for iron pipes: This enhanced mode is described as not effective for iron pipes.
