AUX is an audio input interface. The basic working principle of the AUX interface is that after connecting to the AUX interface, the audio in electronic products can be connected to the car audio through the headphone jack and AUX interface, and the audio can be played in the car audio broadcasting facilities. The USB interface can be inserted with a USB flash drive to play audio. When using it, insert one end into the AUX interface and connect the other end to a video player such as a mobile phone, MP3, or MP4. This allows you to listen to songs or niche music anytime and anywhere, not limited to car music CDs. However, if the playback device runs out of power, the music will also stop (the interface is generally a 3.5mm labeled headphone jack). Aux is the abbreviation for Auxiliary, which is an additional signal line design. In general audio equipment, in addition to the formal output and input terminals, there are often several terminals labeled Aux as standby connection terminals. When there are special applications, such as additional sound output or input, this type of terminal can be used. These standby terminals or lines, whether for input or output, are collectively referred to as Aux. Function: The AUX port is an asynchronous port, mainly used for remote configuration, dial-up connections, and can also be connected to a MODEM through a transceiver. It supports hardware flow control. The AUX port and CONSOLE port are usually placed together because their respective applicable configuration environments are different. The AUX interface establishes a command-line connection between the user and the device, enabling operations that are usually impossible in user mode, such as initialization, restoring initial configurations, and correcting abnormal user modes. It provides a fixed port for the device, which can be used as a standard asynchronous serial port with a maximum speed of 115200bit/s. Using the AUX interface, remote configuration and line backup functions for hardware products can be achieved. Note: When using the AUX interface, make sure to buy the correct connecting cable and avoid plugging the audio cable into the wrong port. It is best to follow the steps in the product's user manual when using the AUX interface. If you still don't know how, you can consult the product's official website or call for assistance.

Tips for Cooling Air-Cooled Motorcycles?

Based on the engine layout, installing a properly sized fan and adjusting its direction can, to some extent, assist in cooling. Following the path of the engine lubricating oil, adding an oil cooler can also help with auxiliary cooling. Air-cooled motorcycles can improve cooling efficiency by switching to high-quality lubricating oil, cleaning the cylinder head cooling fins, and reducing prolonged high-speed riding.

How to reset the tire pressure light on a Golf without a set button?

Turn on the ignition and adjust the tire pressure, then press and hold the tire pressure reset button for 3 seconds. Tire pressure changes slightly as driving mileage increases, so avoid it being too high or too low. As the weather gets hotter and driving speed increases, the internal pressure of the tires rises continuously. It is recommended to slightly lower the pressure in summer.
