This is a programming cable specifically designed for CAN protocol motors. It addresses the issue of setting the wheel diameter and removing the speed limit. If your motor is restricted by the manufacturer to 32KM/H, you may find this speed unsatisfactory, especially when switching to a new frame with a different wheel diameter, which can result in incorrect speed readings on the display, often leading to disappointment. This programming cable can eliminate your concerns and bring you joy. It is straightforward and easy to use. Operation instructions: 1. First, connect and power on the motor. 2. Connect the motor to the main line of the instrument. 3. Connect the ends of the programming cable to the motor and the display screen, respectively. 4. Plug the USB connector of the programming cable into the USB port of your computer or display screen. 5. The indicator light on the programming cable will illuminate, signifying a successful connection. For detailed tutorials, please refer to the video guides. 6. If a 25 fault code appears after connecting, simply press the module button to restore normal operation. For some models, if the wheel diameter setting does not change on the display, exit the setting and return to the main page of the display screen, then re-enter the setting to see the configured wheel diameter.
