Main Unit (Host) Features:

• RJ45 Port: For testing Ethernet cables (Cat5, Cat5e, Cat6, Cat6a, Cat7).
• RJ11/RJ12 Port: For testing phone lines (Cat3).
• USB-C Charging Port: For recharging the internal lithium battery.
• QC/OFF/TEST Switch: Selects between Quality Control mode, Power Off, and Test mode.
• LED Indicators (1-8, G): Display wire status (Pass, Miswire, Open, Short, Shielded).
• Power LED: Indicates power status.
• QC LED: Indicates QC function status.

Remote Unit Features:

• RJ45 Port: Connects to the other end of the Ethernet cable for remote testing.
• RJ11/RJ12 Port: Connects to the other end of the phone line for remote testing.
• LED Indicators (1-8, G): Mirror the main unit's indicators to show wire status.

5. Setup

5.1 Charging the Battery

The NF-468CS features a built-in 1100mAh rechargeable lithium battery. Before first use, or when the battery low voltage indicator appears, charge the device.

1. Connect the supplied USB-C charging cable to the USB-C port on the main unit.
2. Connect the other end of the USB-C cable to a standard USB power adapter (e.g., phone charger, computer USB port).
3. The Power LED on the main unit will indicate charging status. Charge until fully charged.

6. Operating Instructions

6.1 Basic Cable Testing (RJ45, RJ11, RJ12)

This mode tests for continuity, open circuits, short circuits, and miswires.

1. Ensure the main unit and remote unit are separated.
2. Connect one end of the cable to be tested into the appropriate port (RJ45 or RJ11/RJ12) on the main unit.
3. Connect the other end of the cable into the corresponding port on the remote unit.
4. Slide the switch on the main unit to the 'TEST' position.
5. Observe the LED indicators (1-8, G) on both the main and remote units.

Interpretation of LED Indicators:

• All 1-8 LEDs light up sequentially on both units: Indicates a correctly wired cable (straight-through or cross-over, depending on cable type).
• One or more LEDs do not light up: Indicates an open circuit or a broken wire.
• LEDs light up in an incorrect sequence: Indicates a miswire or cross-pair fault.
• Multiple LEDs light up simultaneously or irregularly: Indicates a short circuit.
• 'G' LED lights up: Indicates a shielded cable (STP) has its shield connected correctly.

6.2 QC Function (Crimp Plug Error Detection)

The QC function allows for quick verification of RJ45 connector crimping quality, even without power.

1. Slide the switch on the main unit to the 'QC' position.
2. Connect the crimped RJ45 connector into the RJ45 port on the main unit.
3. Observe the QC LED and the 1-8 LEDs.

Interpretation of QC Indicators:

• QC LED is green and all 1-8 LEDs light up: Indicates a correctly crimped connector.
• QC LED is red or specific 1-8 LEDs do not light up: Indicates a crimping error (e.g., poor connection, open wire).

6.3 POE Test Function

This function allows you to quickly determine the type of power supply and power supply state of a POE switch or router.

1. Connect the network cable from the POE source (switch/router) directly to the RJ45 port on the main unit.
2. Slide the switch on the main unit to the 'TEST' position.
3. Observe the LED indicators (1-8, G) and the Power LED.

Interpretation of POE Indicators:

• 1-2 lights bright or 3-6 lights bright: Indicates an 'end jumper method' (12/36 core power supply).
• 4-5 lights bright or 7-8 lights bright: Indicates a 'middle jumper method' (45/78 core power supply).
• The device can withstand up to 60V, preventing damage from POE sources.

6.4 Direct Connect Network Module Testing

The NF-468CS can be used to test network modules directly, such as wall jacks or patch panels.

1. Connect one end of a short patch cable to the RJ45 port on the main unit.
2. Connect the other end of the patch cable to the network module (e.g., wall jack).
3. Connect the remote unit to the corresponding port on the other end of the cable run (e.g., patch panel).
4. Slide the switch on the main unit to the 'TEST' position and observe the LEDs.
