3. Setup

3.1 Powering the Device

The Treedix USB Cable Tester offers two methods for power supply:

1. CR2032 Button Cell Battery: A CR2032 battery is included and can be installed in the battery compartment.
2. Type-C Interface (5V): The tester can also be powered by connecting a 5V power adapter to its Type-C power input port. This method is useful for extended testing sessions or if a battery is not available.

Important Note:

• ⚠ This device is intended solely for cable testing. Do not connect it to end devices such as smartphones, computers, or other electronic equipment, as this may cause damage to the tester or the connected device.
• ⚠ When using the Type-C interface for power, ensure the power adapter provides a stable 5V output.

4. Operating Instructions

4.1 Basic Cable Testing

To test a USB cable, follow these steps:

1. Ensure the Treedix USB Cable Tester is powered on (either by battery or Type-C 5V input).
2. Identify the correct input and output ports on the tester for the cable you wish to test. For example, for a USB Type-C to Type-C cable, connect one end to the "Type-C 3.0 USB Input" and the other end to the "Type-C 3.0 USB Out" port.
3. Carefully insert both ends of the USB cable into their respective ports on the tester.
4. Observe the LED indicators on the test board. The illuminated LEDs correspond to the functional wires within the cable.

4.2 Interpreting LED Indicators

The LED indicators provide visual feedback on the cable's status and functionality. Each LED corresponds to a specific pin or wire within the USB cable. By observing which LEDs illuminate, you can determine the cable's capabilities and identify any faults.

Figure 4.2.1: Reference guide for interpreting LED patterns to understand cable functionality.

• Test 1 (Charge-Only Cable): When only GND and VBUS LEDs are illuminated, the cable primarily supports charging functionality.
• Test 2 (Charging and Data Cable): If GND, VBUS, D+, and D- LEDs are on, the cable supports both charging and standard data transmission.
• Test 3 (USB 3.0/3.1/3.2 Cable): When GND, VBUS, TX2+, TX2-, CC2, D+, D-, RX1+, RX1-, TX1+, TX1-, CC1, SBU1, SBU2, and SHIELD LEDs are illuminated, it indicates a USB 3.0, 3.1, or 3.2 cable with high-speed data transmission capabilities.
• Test 4 (Comprehensive Functionality Cable): When all LEDs are illuminated (except for one D+ and one D- which may vary based on specific cable design), the cable supports comprehensive functionality including charging, data transmission, audio, and video transmission.
• Fault/Open Circuit: If certain expected LEDs do not light up, it indicates a fault or open circuit in the corresponding wire.

5. Maintenance

5.1 Cleaning

To ensure optimal performance and longevity of your Treedix USB Cable Tester, follow these cleaning guidelines:

• Always power off the device before cleaning.
• Use a soft, dry, lint-free cloth to wipe the exterior of the tester.
• For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the device's surface or internal components.
• Ensure no liquid enters the ports or battery compartment.

5.2 Storage

When not in use, store the USB Cable Tester in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. If storing for an extended period, it is recommended to remove the CR2032 battery to prevent potential leakage.
