1. Introduction
Thank you for choosing the Logilink WZ0011 Network Cable Tester. This device is designed to efficiently test the integrity and configuration of various network and coaxial cables, including RJ45 (UTP/STP), RJ11, and BNC cables. This manual provides detailed instructions for the proper setup, operation, maintenance, and troubleshooting of your cable tester to ensure accurate and reliable results.
2. Product Overview
2.1 Components
The Logilink WZ0011 Network Cable Tester consists of two main parts:
- Main Tester Unit: This unit houses the power switch, test mode selector, and LED indicators for pins 1-8 and GND. It includes RJ45 and BNC ports.
- Remote Unit: This detachable unit is used for testing cables installed over a distance. It also features LED indicators for pins 1-8 and GND, and includes RJ45 and BNC ports.

2.2 Key Features
- Tests RJ45 (UTP/STP), RJ11, and BNC cables.
- Detects open circuits, short circuits, cross-connections, and miswires.
- Verifies pin-to-pin configuration.
- Features two test modes: Normal and Rapid.
- Clear LED indicators for easy fault identification.
- Detachable remote unit for testing installed cables.
3. Setup
3.1 Battery Installation
- Locate the battery compartment cover on the back of the Main Tester Unit.
- Slide or unclip the cover to open it.
- Insert a 9V battery (not included) into the compartment, ensuring correct polarity (+/-).
- Replace the battery compartment cover securely.
3.2 Connecting the Units
For testing short cables or patch cords, the remote unit can be attached directly to the main unit. For testing installed cables, detach the remote unit by sliding it off the main unit. The remote unit can then be connected to one end of the cable, and the main unit to the other.
4. Operating Instructions
4.1 Powering On/Off
Locate the power switch on the Main Tester Unit. Slide the switch to the 'ON' position to power on the device. Slide it to 'OFF' when not in use to conserve battery life.
4.2 Connecting Cables

- For RJ45/RJ11 Cables: Insert one end of the cable into the RJ45 port on the Main Tester Unit and the other end into the RJ45 port on the Remote Unit.
- For BNC Cables: Connect one end of the BNC cable to the BNC port on the Main Tester Unit and the other end to the BNC port on the Remote Unit.
4.3 Selecting Test Mode
The Main Tester Unit features a switch for selecting the test speed:
- 'S' (Slow/Normal) Mode: LEDs illuminate sequentially, allowing for a detailed observation of each pin's status.
- 'ON' (Rapid) Mode: LEDs illuminate quickly, providing a faster test result.
4.4 Interpreting LED Indicators
Once the cable is connected and the tester is powered on, observe the LED indicators on both the Main and Remote Units. The LEDs correspond to the individual pins of the cable (1-8) and a Ground (GND) connection.
- Matching LEDs: If a cable is correctly wired, the corresponding LEDs on both units will light up in sequence (e.g., LED 1 on Main and LED 1 on Remote, then LED 2 on Main and LED 2 on Remote, and so on).
- No LED: Indicates an open circuit or a broken wire for that specific pin.
- Incorrect Sequence/Mismatched LEDs: Suggests a miswire or cross-connection. For example, if LED 1 on the Main Unit lights up, but LED 2 on the Remote Unit lights up, it indicates a cross-connection between pins 1 and 2.
- Multiple LEDs on Remote for Single Main LED: Indicates a short circuit between those pins.
- GND LED: Illuminates if the cable has a ground connection and it is intact.
5. Maintenance
5.1 Cleaning
To clean the device, use a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the casing or internal components.
5.2 Battery Replacement
If the LED indicators become dim or the device fails to power on, replace the 9V battery as described in Section 3.1.
5.3 Storage
Store the cable tester in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the battery to prevent leakage.
6. Troubleshooting
- Device does not power on:
- Check if the power switch is in the 'ON' position.
- Verify that the 9V battery is correctly installed and not depleted. Replace if necessary.
- Inconsistent or no LED indications:
- Ensure cables are securely connected to both the Main and Remote Units.
- Test with a known good cable to rule out a device malfunction.
- Check battery level; low battery can affect LED brightness and test accuracy.
- Remote unit not responding:
- Confirm the remote unit is properly connected to the cable.
- Ensure the cable itself is not severely damaged, preventing signal transmission to the remote unit.
