Frequently Asked Questions - NF-802 Noyafa

How do I test a cable with the NF-802?

Connect the cable to the main unit and the remote unit. Turn on the tester. The LEDs will light up in sequence if the cable is wired correctly. For detailed mapping, refer to the LED pattern table in the manual.

What cables are supported by the NF-802?

The NF-802 supports RJ45 (Cat5e, Cat6), RJ11 (telephone), and BNC (coaxial) cables. Use the appropriate adapter if needed.

Why do some LEDs not light up?

If an LED fails to light, it indicates a broken wire or poor connection. Check the termination or try a known good cable to confirm the tester is working.

Can I test live cables?

No, never test live cables. The NF-802 is designed for unpowered cables only. Testing live cables can damage the tester and pose a safety risk.

What battery does the NF-802 use?

It uses a standard 9V battery (alkaline recommended). When the battery is low, the Power LED will dim or the tester may not function properly.

How do I interpret the LED sequence?

The LEDs correspond to wire pairs 1-2, 3-6, 4-5, 7-8. In a straight-through cable, they light sequentially from 1 to 8. A crossover cable will show a different order. Refer to the manual for specific patterns.

What is the remote unit for?

The remote unit allows one-person testing. Connect the remote to one end of the cable and the main unit to the other. The remote sends signals back to identify shorts or miswires.

The tester does not turn on. What should I do?

First, check the battery. If the battery is fine, ensure the power switch is in the ON position. If still off, the tester may be defective; contact Noyafa support.

Can I test cables longer than 300 meters?

The NF-802 is rated for cables up to 300 meters. Beyond that, signal attenuation may cause unreliable results. For longer runs, use a professional TDR tester.

How do I clean and maintain the tester?

Wipe the exterior with a soft, dry cloth. Do not use liquids or solvents. Store in a dry place. Remove the battery if not used for extended periods.

USER MANUAL NF-802 Noyafa

1. Overview

Intelligent network cable tester

NF-802 is an intelligent network cable tester, uses advanced digital demodulation to realize anti-interference and no noise tracing cables, functions of wiremap, cable tracing, crimping, and port flash. It can test the polarity recognition of the telephone line, standby, off-hook, ringing, and LED indicator in different states. A tool for installation and maintenance of integrated wiring and weak current systems.

2. Using method

2.1.Turn on/off:

Emitter:

1) Push the switch to "ON" to turn on, Defaulting to to the dual mode of scan/wiremap, Now the LED indicator of the scan button is on.

2) Push the switch to the "Off" to shut down

Receiver

1) Shutdown state, turn the receiver knob clockwise

click sound to indicate power on.

counterclockwise. "click" sound to indicate turn it off

2.2. Wiremap

The boot defaults to "SCAN/Wiremap" dual mode, the SCAN button indicator is always on, short press the SCAN button to switch to the QC mode, SCAN button indicator flashes, short press again to enter the SCAN/QC dual mode.

Wiremap function is mainly used to detect the line sequence, short circuit, open circuit, and cross of network cables, and The results display by the sequence LED. Insert the end of lan cable into RJ45 interface of the emitter, and insert the other end into RJ45 interface of the receiver, then judge the cable condition by the LEDS sequence light, as follows:

1) Pass: The LED lights of the transmitter and receiver will flash

green one by one.

E:1-2-3-4-5-6-7-8

R:1-2-3-4-5-6-7-8

2) Short: If two or more cables are short circuited, the corresponding lights won't be on of the receiver while the emitter remains normal.

E:1-2-3-4-5-6-7-8

P:1×24×678

E:1-2-3-4-5-6-7-8

B-1 Y 3.4 Y 6.7.8

4) Cross : If Pin2&5 is cross, when LED2 of the emitter lights, LED5 of the receiver light at the same

E:1-2-3-4-5-6-7-8

R:1-5-3-4-2-6-7-8

2.3. Cable tracing:

1) Turn on the receiver to enter the SCAN/ Wiremap dual mode, SCAN button indicator light is always on.

2) After selecting the mode, connect the network cable/telephone cable to be tested to the RJ45/RJ11 port of the emitter.

3) Turn the receiver knob clockwise to turn on, adjust the sensitivity of the received signal to the maximum, use the receiver probe to approach the cable, when the receiver receives the signal, the receiver emits a "Beep beep" sound, and the receiver line sequence light turns red indicating the signal strength. The stronger the received signal, the louder the sound and the more the lights are on, so the approximate position of the cable can be quickly located.

4) After determining the approximate position of the cable, appropriately reduce the receiver's signal sensitivity to accurately locate the target line.

Note: The line sequence light of the receiver is green to indicate the wiremap result, and red to indicate the strength of the received signal

2.4. QC for crimping crystal:

Short press the transmitter "QC" button to enter the QC test mode. The QC button indicator light is on. Connect the network cable/telephone cable to the crimping port of the emitter, and the crimping QC LED will be on. The result is as follows:

1) QC pass:LED1\~LED8 of the emitter are all light. E:1-2-3-4-5-6-7-8

2) QC is not pass: the crimping light of the emitter is shining as follows.

Telephone line

QC pass for 6P6C E:x-2-3-4-5-6-7-x QC pass for 6P4C E:x-x-3-4-5-6-x-x QC pass for 6P2C E:x-x-x-4-5-x-x-x

2.5. Port flash:

Short press the "FLASH" button, the port flash button indicator is on, and the port flash indicator light is on. Insert the network cable into the RJ45 interface of the emitter, and the other end is connected to the switch/router. The indicator flash every 3-4 seconds and transmit the flashing signal to the switch/router. The corresponding interface indicator of the switch/router flash at a frequency of 3-4 seconds simultaneously, and the target line is judged.

Note: When PoE is connected, The wiremap sequence LED will light to show which cores supply power.

2.6. Telephone line status detection:

Push the switch to the "telephone line" position, the telephone line is connected to the emitter RJ11 interface, the results are as follows:

1) Polarity detection of telephone line.

When the green light is on, the telephone line 3P is positive pole and 4P is negative pole

When the red light is on, the telephone line 3P is negative pole and 4P is positive pole

2) Telephone status detection

Indicator light is on ---- The phone is idle

Green and red lights flash alternately ---- the telephone is ringing Indicator light dims ---- off — hook(the telephone is in a conversation)

Pay attention :Indicator light color based on Polarity detection of telephone line.

2.7.NCV:

Short press the receiver "NCV" button to enter the NCV test mode, the NCV button indicator light is on, when the receiver probe is close to the cable or socket and other equipment. If there is more than 40V AC, the receiver will emit a "di di di" sound.

2.8. Lighting:

Short press the receiver "light" button to turn on the receiver LED flashlight, short press again to turn it off.

2.9. Headphones:

Headphone function: When testing in a noisy environment, wear headphones for operation to avoid external interference.

2.10. Low battery prompt and charging

1) Low battery prompt function: When the battery power is lower than the power required for the normal operation of the instrument, Power indicator flashes.

2) TYPE-C USB charging function status indication: when charging, the red indicator light is on, When the battery is full, the red indicator light is off.
