Video 6.1: Official NOYAFA NF-8209 Network Cable Tester Demonstration. This video demonstrates the PoE test, continuity test, cable length measurement, and cable scanning functions.
6.1 PoE Information Testing
This function identifies which pins are providing power, detects the voltage, and identifies the type of Power Sourcing Equipment (PSE) (e.g., IEEE 802.3af/at standard).
- Connect one end of the network cable to the PoE port on the Emitter.
- Connect the other end of the cable to a PoE switch or device.
- On the Emitter's main menu, select the PoE testing function.
- The LCD screen will display information such as PoE standard (e.g., IEEE 802.3af), Endspan/Midspan, and voltage.

Figure 6.1.2: Detailed display of PoE test results, including pin power and voltage.
Refer to Video 6.1 from 0:05 to 0:21 for a demonstration of PoE testing.
6.2 Cable Continuity Testing (Wiremap)
This function tests the physical status of STP and UTP LAN cables, detecting open circuits, short circuits, and cross-connections.
- Connect one end of the network cable to the CONT port on the Emitter.
- Connect the other end of the cable to the RJ45 port of the Remote Identifier.
- On the Emitter's main menu, select the Continuity testing function.
- Press OK to start testing. The screen will display the wiremap results (e.g., 1-1, 2-2, etc. for a good cable).

Figure 6.2.2: Example of continuity test results for a correctly wired cable.
Refer to Video 6.1 from 0:22 to 0:40 for a demonstration of cable continuity testing.
6.3 Cable Length Measurement
The NF-8209 can accurately measure the length of LAN cables (Cat5, Cat6) up to 200 meters using Time Domain Reflectometry (TDR) technology. It can also locate the distance to a fault.
- Ensure the LAN cable to be tested is de-energized and disconnected from all network devices.
- Connect one end of the cable to the Length/Flash port on the Emitter. The other end should be open (not connected to anything).
- On the Emitter's main menu, select the Length measurement function.
- The LCD screen will display the cable length in meters. If a fault is detected, it will show the distance to the fault.

Figure 6.3.2: Display showing the measured length of the network cable.
Refer to Video 6.1 from 0:41 to 1:05 for a demonstration of cable length measurement.
6.4 Digital Cable Scanning (Wire Tracking)
This function helps locate specific cables among a bundle, even in noisy environments, using digital, analog, or PoE scan modes.
- Connect one end of the target cable to the SCAN port on the Emitter.
- On the Emitter's main menu, select the Scan function and choose your desired mode (Digital, Analog, or PoE).
- Ensure the Receiver's mode switch matches the Emitter's selected scan mode.
- Use the Receiver to trace the cable. The Receiver will emit an audible tone and/or visual indication when it detects the signal from the target cable. Adjust sensitivity (SEN) as needed.

Figure 6.4.2: The Emitter's display showing the selectable scan modes.
Refer to Video 6.1 from 1:06 to 1:51 for a demonstration of cable scanning.
6.5 NCV (Non-Contact Voltage) Function
The Receiver unit features an NCV function to detect the presence of AC voltage (50V-1000V) without direct contact, enhancing safety.
- Turn on the Receiver unit.
- Move the tip of the Receiver close to the suspected live wire or electrical outlet.
- If AC voltage is detected, the NCV indicator light on the Receiver will illuminate, and an audible alarm may sound.
Figure 6.5.1: Using the NCV function to detect AC voltage for safety.
6.6 Hub Blink
The Hub Blink function helps locate the network port by causing the port light on a Hub/Switch to flash. This is available for 10M/100M Hub/Switches.
- Connect one end of the network cable to the Length/Flash port on the Emitter.
- Connect the other end of the cable to a port on the network switch.
- On the Emitter's main menu, select the Hub Blink function.
- The corresponding port light on the connected switch will begin to flash, allowing for easy identification.

8. Troubleshooting
If you encounter issues with your NF-8209, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead batteries; Incorrect battery installation. | Replace batteries; Ensure batteries are installed with correct polarity. |
| Inaccurate cable length measurement. | Cable not de-energized; Other devices connected to the cable; Cable length outside range. | Disconnect cable from all devices; Ensure cable length is within 200m. |
| No signal during cable scanning. | Emitter and Receiver modes do not match; Low sensitivity on Receiver. | Set both Emitter and Receiver to the same scan mode; Increase Receiver sensitivity. |
| Continuity test shows 'Open' or incorrect wiremap. | Cable fault (open, short, cross); Remote not connected or faulty; Wrong port used. | Inspect cable for damage; Ensure remote is properly connected; Use the correct 'CONT' port. |
