WANLUTECH LT-300 Rechargeable Network Cable Tester User Manual

1. Product Overview

The WANLUTECH LT-300 is a versatile and rechargeable network cable tester designed for maintaining and installing various types of cables. It integrates multiple functions including cable tracing, wire map continuity testing, cable length measurement, Power over Ethernet (PoE) detection, Non-Contact Voltage (NCV) mode, and port flashing capabilities.

The image displays the WANLUTECH LT-300 Network Cable Tester, consisting of two main components: the larger main unit on the left with a digital screen, and the smaller, elongated remote probe on the right. The main unit features a 3-inch display showing 'Network Cable Tester' and 'Cable Tester' with a battery indicator and a wire map diagram. Below the screen are control buttons including power, navigation arrows, a 'REF' button, an 'HOLD' button, and a settings icon. The remote probe, primarily orange and black, has a power button, mode button, speaker icon, light icon, and indicators for SCAN, NCV, and RJ45. It also features a rotary dial and buttons for 100M, 1000M, SNCV, DIRECT, CROSS, and OTHER modes. Both units are predominantly black with orange accents.

Key Features:

• Rechargeable Design: Equipped with a 3.7V 2000mAh lithium battery for extended use.
• Digital Cable Tracer: Efficiently searches and identifies UTP, BNC, and shielded cables in bundles, utilizing a secondary code digital mode to reject noise.
• Wire Map & Continuity Test: Tests twisted pair cables for continuity, identifying open, short, and cross faults. Displays cable sequence and speed (1Gbps/100Mbps). Detects near-end, mid-end, and far-end fault points for RJ45 cables.
• Cable Length Measurement: Accurately measures network cable lengths from 1 to 600 meters.
• PoE Testing: Detects PoE power supply protocols (IEEE802.3bt/at/af and non-standard), identifies power supply wire pairs, measures voltage, and provides real-time power readings for PD load devices.
• Non-Contact Voltage (NCV) Mode: Detects AC voltage with visual and audible alarms, indicating signal strength.
• Port Flashing: Quickly locates the switch port connected to the tester by causing the port to flash at a fixed frequency. Displays port rate (1Gbps/100Mbps/10Mbps).
• PD Power Detection: Identifies power supply pins (1236, 4578) and distinguishes between standard (blinking light) and non-standard (solid light) PoE, supporting 24V and 48V PoE equipment.

2. Setup and Charging

2.1 Unpacking

Carefully unpack the LT-300 tester and its accessories. Ensure all components listed in the 'What's in the Box' section are present.

2.2 Charging the Device

The LT-300 comes with a built-in 3.7V 2000mAh lithium battery. Before first use, it is recommended to fully charge the device.

• Connect the provided charging cable to the charging port on the main unit.
• Connect the other end of the charging cable to a standard USB power adapter (not included) or a computer USB port.
• The battery indicator on the screen will show charging status. A full charge typically takes a few hours.
• Disconnect the charger once the battery is fully charged to prolong battery life.

2.3 Powering On/Off

Press and hold the power button on the main unit to turn the device on or off. The 3-inch screen will illuminate upon startup.

3. Operating Instructions

3.1 Cable Continuity Testing (Wire Map)

This function tests the integrity of twisted pair cables (e.g., RJ45) and identifies wiring faults.

• Connect one end of the network cable to the RJ45 port on the main unit.
• Connect the other end of the cable to the RJ45 port on the remote unit.
• Select the 'Wire Map' or 'Continuity Test' mode on the main unit (refer to screen prompts or mode button).
• The screen will display the cable sequence and identify any open, short, or cross-over faults. It can also indicate the location of the fault (near-end, mid-end, or far-end).

3.2 Cable Length Measurement

Measure the precise length of network cables.

• Connect the network cable to the RJ45 port on the main unit. The remote unit is not required for length measurement.
• Select the 'Length Measurement' mode.
• The device will automatically measure and display the cable length in meters (range: 1-600 meters).

3.3 PoE Testing

Verify Power over Ethernet functionality and parameters.

• Connect the PoE input port of the tester to a PoE switch or power source.
• Connect the PoE output port of the tester to a PoE-powered device (e.g., IP camera).
• Select the 'PoE Test' mode.
• The screen will display the PoE protocol (IEEE802.3bt/at/af or non-standard), power supply wire pairs, voltage, and real-time power consumption of the connected PD device.

3.4 Non-Contact Voltage (NCV) Mode

Detect the presence of AC voltage without direct contact.

• Activate the 'NCV' mode on the remote probe.
• Move the probe near the suspected AC voltage source.
• The power-seeking indicator on the probe will flash, and an audible beep alarm will sound if AC voltage is detected. Indicators 1-5 will flash to show signal strength.

3.5 Port Flashing

Quickly identify the corresponding port on a switch or router.

• Connect the main unit to a port on the network switch or router.
• Activate the 'Port Flashing' function.
• The connected port on the switch will flash at a fixed frequency, making it easy to locate. The tester's screen will also display the port's current rate (1Gbps/100Mbps/10Mbps).

3.6 PD Power Detection

Determine the power supply method for PoE devices.

• Connect the PD port of the toner probe to a power supply device such as a PoE switch or PSE.
• Observe the indicators on the PD port:
• If powered by 1236 pins, the 1236 indicator will be on.
• If powered by 4578 pins, the 4578 indicator will be on.
• If powered by both, both lights will be on.
• A solid light indicates non-standard PoE access.
• A blinking light indicates standard PoE access.
• This function supports testing 24V and 48V PoE power supply equipment.

3.7 Digital Cable Tracing

Locate specific cables within a bundle.

• Connect the main unit to the cable you wish to trace.
• Use the remote probe to scan the cable bundle.
• The probe will emit an audible signal when it detects the target cable, even in noisy environments, thanks to its secondary code digital mode. This also works for shielded cables.

4. Maintenance

4.1 Cleaning

Regularly clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the ports or screen area.

4.2 Battery Care

To maximize battery life, avoid fully discharging the battery frequently. If storing the device for an extended period, charge it to approximately 50% and store in a cool, dry place. Recharge every 3-6 months if not in use.

4.3 Storage

Store the LT-300 in a clean, dry environment, away from direct sunlight, extreme temperatures, and high humidity. Keep it in its original packaging or a protective case when not in use to prevent damage.
