4. Product Overview

The NF-810 consists of two main units: the Emitter and the Receiver. Familiarize yourself with the components of each unit.

Figure 4.1: Labeled diagram of the NF-810 Emitter and Receiver units.

Emitter Unit

• RJ45 Port: For connecting Ethernet cables.
• RJ11 Port: For connecting telephone lines.
• Function Dial: Selects between CONT (Continuity), SCAN, OFF, TONE, and SHORT modes.
• Wiremap Indicators (1-8, G): LEDs to display wire status.

Receiver Unit

• Probe: For tracing cables and detecting signals.
• LED Light: Illuminates dark work areas.
• Power/SCAN Indicator: Shows power status and scan activity.
• Sensitivity Knob: Adjusts the sensitivity of the receiver.
• Earphone Port: For connecting headphones for clearer tone detection.
• LED Button: Activates the LED light.
• Wiremap Indicators (1-8, G): LEDs to display wire status (Mid-span, End-span).
• RJ45 Port: For connecting Ethernet cables for wiremap testing.

5. Setup

5.1 Battery Installation

The NF-810 requires 1 Lithium Metal battery (9V laminated battery) for operation. Ensure the battery is installed correctly in both the Emitter and Receiver units.

1. Locate the battery compartment cover on the back of each unit.
2. Open the cover by sliding or unscrewing it.
3. Insert the 9V battery, observing the correct polarity (+/-) markings.
4. Close the battery compartment cover securely.

6. Operating Instructions

6.1 Cable Measurement (Wiremapping)

This function detects breaks, shorts, crossovers, and shielding issues in LAN (RJ45) and telephone (RJ11) cables.

1. Connect one end of the cable to the RJ45 or RJ11 port on the Emitter unit.
2. Connect the other end of the cable to the corresponding RJ45 port on the Receiver unit.
3. Turn the Emitter's function dial to the 'CONT' position.
4. Observe the wiremap indicators (LEDs 1-8 and G) on both the Emitter and Receiver.
5. Normal Connection: LEDs on both units will light up sequentially from 1 to 8, then G (for shielded cables).
6. Open Circuit: If a specific LED does not light up, that wire is open.
7. Short Circuit: If two or more LEDs light up simultaneously, a short circuit exists between those wires.
8. Crossover: If the sequence of LEDs is incorrect (e.g., Emitter 1 lights up, but Receiver 2 lights up), a crossover is detected.

6.2 Wire Tracing (Scanning/Tone Function)

This function helps locate and identify specific cables within a bundle or wall.

1. Connect one end of the target cable to the RJ45 or RJ11 port on the Emitter unit. For non-RJ cables, use the alligator clip cable to connect to the wire pair.
2. Turn the Emitter's function dial to the 'SCAN' or 'TONE' position. The Emitter will generate an audible tone.
3. Turn on the Receiver unit and adjust the sensitivity knob to a suitable level.
4. Use the Receiver's probe to scan the cables or wires you suspect are the target.
5. The Receiver will emit a louder sound and/or the yellow-green signal indicator will illuminate more brightly when it detects the tone from the target cable.

6.3 PoE Tester Function

The NF-810 can detect Power over Ethernet (PoE) presence, identify PoE switch types, and measure the number of PoE power supply cores.

1. Connect the Ethernet cable from the PoE source (e.g., PoE switch) to the RJ45 port on the Receiver unit.
2. The Receiver will automatically detect PoE presence.
3. Observe the LEDs on the Receiver unit. They will indicate the PoE power supply cores (Mid-span or End-span) and potentially the voltage.
4. Caution: The device is designed to withstand voltages up to 60V. Do not test circuits exceeding this voltage to prevent damage.

6.4 Telephone Line Detection

This feature allows for detecting the polarity, on/off status, and standby status (idle, ringing, talk) of telephone lines.

1. Connect the telephone line to the RJ11 port on the Emitter unit.
2. Turn the Emitter's function dial to the 'TEL' position (if available, or use 'CONT' and interpret the LEDs).
3. The LEDs will indicate the line status:
   • Idle: Specific LEDs will light up, indicating a normal standby line.
   • Ringing: LEDs may flash or change pattern during an incoming call.
   • Talk: LEDs will indicate the active talk state and polarity.

6.5 LED Lighting

The Receiver unit is equipped with an LED light to assist in dark environments.

• Press the 'LED' button on the Receiver unit to turn the light on or off.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your NF-810 tester.

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Care: Remove batteries if the device will not be used for an extended period to prevent leakage.
• Probe Protection: Ensure the Receiver's probe is not bent or damaged during storage or transport.
