Treedix USB Cable Data Line Test Board User Manual

1. Introduction

The Treedix USB Cable Data Line Test Board, also known as the USB Cable Checker, is a reliable tool designed to assess the connection status and integrity of various USB cables. It provides a straightforward method for users to identify issues such as broken connections or physical damage within a cable's internal wires.

This device is equipped with 24 LED indicators that visually represent the status of each wire. By simply plugging the two ends of a USB cable into the corresponding connectors on the board, users can quickly determine the cable's functionality. Please note that this tester is designed for continuity and integrity checks and does not test the cable's power-bearing capacity.

2. Key Features

• Reliable USB Cable Testing: Capable of testing various USB cable types, including Type-B 3.0, Type-B 2.0, Type-C 3.0 (compatible with Type-C 3.1/3.2), Micro-B 3.0, Micro-B 2.0, Mini-B 2.0, and Lightning cables.
• Convenient and Practical Design: Features a portable and compact design, making it easy to carry and use in various settings.
• Multiple Power Supply Options: Supports power via a CR2032 button battery (included) or an external power supply (Vin) ranging from 3-12V. The Vin input includes reverse connection protection.
• Clear LED Indicators: Test results are clearly displayed through 24 individual LED indicators, with each LED corresponding to a specific pin or wire within the cable.
• Multi-functional Utility: Supports a wide range of interface types, enabling quick detection of data cable abnormalities and internal short circuits that could impair normal operation.

4. Setup

4.1. Power Supply Options

The Treedix USB Cable Checker can be powered in two ways:

1. CR2032 Button Battery: A CR2032 coin battery is included and can be installed directly into the battery holder on the board.
2. External Power Supply (Vin): For continuous operation or if a battery is not preferred, an external power supply ranging from 3V to 12V can be connected to the Vin input. This input features reverse connection protection for safety.

4.2. Battery Installation

To install the CR2032 battery:

• Locate the CR2032 battery holder on the board.
• Tilt the battery end into the positive terminal of the carabiner (clip) and press down on the battery until it clicks securely into place. Ensure the positive (+) side of the battery faces upwards.

5. Operating Instructions

The Treedix USB Cable Checker is designed for intuitive operation. Follow these steps to test your USB cables:

1. Prepare the Tester: Ensure the device is powered on, either by the installed CR2032 battery or an external Vin supply.
2. Connect the Cable: Plug one end of the USB cable you wish to test into the appropriate input port on the left side of the board (e.g., Type-A 3.0, Type-A 2.0, Type-C 3.0).
3. Connect the Other End: Plug the other end of the USB cable into the corresponding output port on the right side of the board (e.g., Type-B 3.0, Micro-B 3.0, Mini-B 2.0, Lightning, Micro-B 2.0).
4. Observe LED Indicators: Once both ends of the cable are connected, the 24 LED indicators on the board will illuminate. Each LED corresponds to a specific wire or pin within the cable.
• If an LED lights up, it indicates that the corresponding wire has continuity and is functioning correctly.
• If an LED does not light up, it indicates a broken connection or an open circuit in that specific wire.
• If multiple LEDs light up unexpectedly or in an unusual pattern, it may indicate a short circuit between wires.
5. Interpret Results: By observing which LEDs illuminate, you can determine the integrity of each wire within the cable. For example, a cable designed for data transfer (e.g., USB 3.0) should illuminate more LEDs than a charge-only cable.

6. Maintenance

To ensure the longevity and accurate performance of your Treedix USB Cable Checker, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the surface of the device. Avoid using abrasive cleaners or solvents, as they may damage the board or markings.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the CR2032 battery to prevent leakage.
• Handling: Handle the board with care to avoid physical damage to the connectors, LEDs, or circuit components. Avoid dropping the device.
• Battery Replacement: Replace the CR2032 battery when the LED indicators appear dim or the device does not power on reliably.
