3. Included Components

The package includes the Aideepen USB Cable Test Board. Please note that a CR2032 button battery is not included and must be purchased separately.

4. Setup

4.1 Powering the Device

The USB Cable Test Board can be powered using one of two methods:

1. CR2032 Button Battery: Insert a CR2032 button battery into the designated battery holder on the board. Ensure the positive (+) terminal of the battery aligns with the positive contact on the holder.
2. External DC Power (Vin): Connect an external DC power supply (3-12V) to the 'Vin' input port. This port provides reverse connection protection.

4.2 Battery Installation

To install the CR2032 battery:

1. Locate the battery holder on the test board.
2. Slide the battery cover to the right (towards the CR2032 battery side) to remove it.
3. Insert the CR2032 button battery, ensuring the positive (+) pole aligns with the safety lock's positive contact.
4. Gently press the battery downwards to secure it in place.
5. Replace the battery cover by sliding it back into position.

5. Operation

5.1 Testing a USB Cable

To test a USB cable:

1. Ensure the test board is powered on (either via CR2032 battery or external Vin).
2. Connect both ends of the USB cable you wish to test into the corresponding ports on the test board. For example, if testing a USB-C to USB-A cable, connect the USB-C end to a Type-C port and the USB-A end to a Type-A port.
3. Observe the LED indicators. The LEDs corresponding to the functional pins will light up.

5.2 Interpreting LED Indicators

The 24 LED indicators provide visual feedback on the cable's internal wiring. Each LED corresponds to a specific pin or function within the USB cable. By observing which LEDs illuminate, you can determine the cable's capabilities and identify any faults.

• GND and VBUS Lamps Lit: If only the GND (Ground) and VBUS (Voltage Bus) lamps are lit, it indicates that the USB cable primarily supports charging functionality.
• GND, VBUS, D+, D- Lamps Lit: If GND, VBUS, D+ (Data Positive), and D- (Data Negative) lamps are lit, the USB cable supports both charging and data transfer.
• All Lamps Lit (excluding D+ and D- if applicable): If all relevant lamps are lit (e.g., GND, TX2+, TX2-, VBUS, CC2, D+, D-, SBU2, RX1+, RX1-, GND), it indicates that the USB cable supports charging, high-speed data transfer (e.g., USB 3.0/3.1/3.2), audio/video transmission, and other advanced functionalities.

7. Troubleshooting

• No LEDs light up when a cable is connected:
  • Ensure the device is properly powered. If using a CR2032 battery, check if it is inserted correctly with the positive (+) terminal facing up and securely in place. Replace the battery if it is depleted.
  • If using external power, verify that the DC3-12V power supply is connected to the 'Vin' port and is functioning correctly.
  • Confirm that both ends of the USB cable are fully inserted into the correct ports on the test board.
• LEDs show unexpected results:
  • Refer to the "Interpreting LED Indicators" section (5.2) and the "Pinout Diagram" (Figure 8) for a detailed explanation of each LED's function.
  • Ensure the cable being tested is compatible with the ports used on the test board.
  • Test with a known good cable to verify the tester's functionality.

8. Maintenance

To ensure the longevity and optimal performance of your Aideepen USB Cable Test Board:

• Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
• When not in use for extended periods, remove the CR2032 battery to prevent leakage.
• Handle the board with care to prevent damage to the connectors or electronic components.
