5. Istruzzjonijiet Operattivi
The tester uses LED indicators to show the continuity and functionality of each pin within the connected cables. A lit LED indicates a successful connection for that specific pin.
5.1 USB Cable Testing
To test a USB cable, connect one end of the cable to the corresponding USB port on the left side of the tester (USB Type-A or USB Type-C) and the other end to the corresponding port on the right side (USB Type-C, Micro-AB, or Lightning). The LEDs will illuminate to indicate the status of each data and power line.

Figure 5.1: The tester board showing illuminated LEDs during a test.
5.1.1 Testing USB Type-C Cables
Connect both ends of the USB Type-C cable to the Type-C ports on the tester. Observe the LEDs for VBUS, GND, D+, D-, CC1, CC2, TX1, TX2, RX1, and RX2 to confirm full functionality, including data and charging capabilities.

5.1.2 Testing Micro-AB USB Cables
Connect the Micro-AB end of the cable to the Micro-AB port on the right side and the other end (e.g., USB Type-A) to its corresponding port on the left. Check the LEDs for VBUS, GND, D+, and D-.

5.1.3 Testing Lightning Cables
Connect the Lightning end of the cable to the Lightning port in the center and the other end (e.g., USB Type-A) to its corresponding port. Verify the LEDs for VBUS, GND, D+, and D-.

5.2 RJ45 Network Cable Testing
Connect both ends of the RJ45 network cable to the RJ45 ports on the tester. The LEDs will indicate the continuity of each of the 8 cores. This helps identify if the cable supports 100Mbps (4 cores) or 1000Mbps (8 cores) connections and if any wires are broken or miswired.

5.3 LED Indicator Interpretation
The board features a detailed layout of pin labels next to each LED, corresponding to the various USB and RJ45 connections. Refer to the diagram below for a clear understanding of each indicator.

Figure 5.3: Labeled diagram of the Gikfun USB Cable Tester Board.
Each LED corresponds to a specific pin or wire within the cable. If an LED is lit, it indicates that the corresponding pin has continuity. If an LED remains off when it should be lit for a functional cable, it suggests a break or fault in that specific wire.

6. Manutenzjoni
To ensure the longevity and accurate performance of your Gikfun USB Cable Tester Board, follow these maintenance guidelines:
- Tindif: Use a soft, dry cloth to wipe the surface of the board. Avoid using abrasive cleaners or solvents that could damage the components or labels.
- Ħażna: Store the tester in a cool, dry place away from direct sunlight, excessive heat, and moisture.
- Immaniġġjar: Handle the board with care to avoid dropping it or subjecting it to strong impacts, which could damage the electronic components or connectors.
7 Issolvi l-problemi
7.1 No LEDs Light Up
- Iċċekkja l-Provvista tal-Enerġija: Ensure a DC 5V-12V power supply is correctly connected to the barrel jack. Verify the power supply is functional and providing the correct voltage.
- Konnessjoni tal-Cable: Confirm that the cable being tested is properly inserted into both the input and output ports on the tester.
7.2 Incorrect LED Readings
- Cable Orientation (USB-C): For USB-C cables, ensure the cable is inserted correctly. USB-C is reversible, but some internal connections might be sensitive to orientation on certain testers. Try flipping the cable.
- Cable Type Mismatch: Ensure you are interpreting the LEDs based on the correct cable type (e.g., a charge-only USB cable will not light up data line LEDs).
- Damaged Cable: If certain LEDs do not light up for a cable that should be fully functional, the cable itself may be damaged or faulty.
