How to use aux interface? What do you mean by aux interface?

AUX interface refers to the audio input interface, which can output the audio of electronic audio devices, including mp3 (commonly used earphone interface), and the music of these devices can be output through the car audio system.

Aux is the abbreviation of "auxiliary", which is an additional signal circuit design. In general audio equipment, in addition to the formal output and input terminals, there are usually several output and output terminals marked "Aux" as preparatory connections.

This can be used for special applications such as extra sound output or input. This preparation terminal or circuit, whether it is an output or an input, is collectively called an auxiliary circuit.

These interfaces are usually available on three or more layers of hardware routing of major network providers. (auxiliary port)

AUX port is an asynchronous port, which is mainly used for remote configuration, dial-up connection and modem connection through transceiver. Support hardware flow control. Auxiliary ports and console ports are usually placed together because they are suitable for different configuration environments.

AUX interface establishes a command line connection between users and devices. Perform some operations on the device that are not usually performed in user mode, such as initialization, restoring initial configuration and correcting abnormal user mode.

The device has a fixed port, which can be used as an ordinary asynchronous serial port. The maximum speed is 1 15200 bit/s, and the AUX interface can realize remote configuration of hardware products, line backup and other functions.
