Frequently Asked Questions - NF-468V Noyafa

What types of cables can the Noyafa NF-468V test?

The NF-468V tests RJ45 network cables (8P8C) and RJ11/RJ12 telephone cables (6P4C/6P6C). It does not test BNC coax cables (use NF-468N for that).

How do I power the NF-468V?

The tester can be powered by a 9V battery (not rechargeable) or by an external power source connected to the charging port (e.g., AC adaptor or power bank). Note: the charging port supplies power to the device, not to recharge the battery.

What do the different LED indicators mean?

LEDs 1-8 (and G for shielded cables) light up in sequence if the cable is wired correctly. If they light out of sequence, wires are crossed. If an LED stays off, that wire is open. If two adjacent LEDs remain off, they are shorted. Refer to the manual for detailed interpretation.

What is the difference between 'ON' and 'S' modes?

ON mode runs the test at normal speed. S mode (slow) cycles through the pins at a slower pace, making it easier to visually track each LED for troubleshooting.

Can I test shielded cables (STP)?

Yes. The tester includes a G (ground) LED that will light in sequence for shielded cables. Ensure the shielding is properly connected.

How do I test a telephone cable?

Connect the cable to the RJ11/RJ12 ports on both the main and remote units. For RJ11 (6P4C), LEDs 2-5 will light sequentially; for RJ12 (6P6C), LEDs 1-6 will light. If the cable is faulty, the same rules for open/short/cross apply.

Why do all LEDs stay off when I connect a cable?

This indicates less than two wires are connected correctly or the cable is completely open. Check the connections and ensure both ends are securely plugged in and the correct port type is used.

Is it safe to test live cables?

No. The NF-468V is designed for passive cable testing only. Never use it on live circuits as it may damage the device and pose a safety risk.

What does 'crossed wires' look like on the tester?

If wires are crossed (e.g., pin 2 and pin 4 swapped), the remote LEDs will light out of sequence. For example, if the main shows 1-2-3-4..., the remote may show 1-4-3-2... meaning pins 2 and 4 are crossed.

How do I maintain the NF-468V?

Clean the device with a dry, soft cloth. Avoid moisture, solvents, or abrasive cleaners. Store in a dry place. The only user-serviceable part is the 9V battery replacement.

Please read and learn safety instructions before use or maintain the equipment

Instructions:

● The basic NF-468N & NF-468V LAN tester is used for testing the pin out status only.
NF-468N is to check physical status of network cable & coax cable.
NF-468V is to check physical status of network cable & telephone cable.
- Two types of power supply: one is 9V battery, the other type is AC Charge adaptor / power bank connects to the charging port.

Warnings:

● The devices should not be used on a live circuit.
● The charging port is to supply power for the device, not for the battery.

Operation

Turn on the tester and choose "ON" for normal speed and "S" for slow speed light indication. Plug in your cord to be tested to the main unit and the remote and if all correct the indicators will light up in sequence from 1 to 8 (or G if shielded). If they do not light up in in sequence you will have a short circuit, wrong wiring or open circuit in your patch cord or wiring network that is being tested.

1. If there is an open circuit on any of the wire connections then the corresponding light on both the main and remote testers will remain off.
2. If less than two wires are connected correctly then all of the lights on the main and remote testers will remain off.
3. If any connections are crossed, for example if one end of the wire is connected to connection No.2 and the other end is connected to connection No.4 then the lights on the remote will turn on out of sequence, the following sequence of lights will show on the testers.
   Main Tester: 1-2-3-4-5-6-7-8-G
   Remote Tester: 1-4-3-2-5-6-7-8-G

It can be seen that lights for connection No2 and connection No.4 are out of sequence which indicates they are crossed.

1. If two wires are short circuited then the corresponding lights on the remote will remain off.

2. Matching test leads are required on the main and remote testers, e.g. both RJ45 or both RJ11 or BNC.

Test BNC Cable (NF-468N)

1. Switch on the power, choose "ON" or "S", the power light will turn on.
2. Connect RJ45 port of BNC adapter with remote tester, then insert one end of BNC cable into BNC port of main tester, the other end into BNC connector. The lights of the main tester and remote tester will turn on sequentially from 1 to 2 and circulates.

1. If the cable is breakage, disorder, short circuit, the result is as what was said in operation.

2. After operation, turn off the tester.

Test RJ45 Cable (NF-468V/NF-468N)

1. Switch on the power, choose "ON" or "S", the power light will turn on.
2. If UTP tested, the lights of the main tester and remote tester will turn on sequentially from 1 to 8 and circulates; If STP tested, the lights of the main tester and remote tester will turn on sequentially from 1 to G and circulates.
3. If the cable is breakage, disorder, short circuit, the result is as what was said in operation.
4. After operation, turn off the tester.

Test RJ11 Cable(NF-468V)

1. Switch on the power, choose "ON" or "S", the power light will turn on.
2. If RJ11 cable tested, the lights of the main tester and remote tester will turn on sequentially from 2 to 5 and circulates. If RJ12 tested, the lights of the main tester and remote tester will turn on sequentially from 1 to 6 and circulates.
3. If the cable is breakage, disorder, short circuit, the result is as what was said in operation.
4. After operation, turn off the tester.
