Intelligent background music is not an emerging industry, but it has been well known to most people in recent years. It is a relatively special hardware device, not only related to the home environment, its installation is directly integrated with the internal structure of the house, so the security of intelligent background music is more concerned than other smart devices. However, because only professional engineers know how to install such products, sometimes problems such as delivery and work make the owner unable to wait for the assembly, which makes it very easy to ignore some details and cause danger.
Xiaobian teaches you how to install the intelligent background music system today. First of all, at this stage, most of the intelligent background music needs to be dark before the decoration. Take the LV-630, a split-type player with a standard 86-bottom box on the market, as an example.
First, recognize all kinds of interfaces
The RJ45 interface is usually used for data transmission, both of our usual network cable interfaces. Because LV-630 is a form of strong and weak power separation, you can see that there are two RJ45 interfaces: one is to connect the router into the network, and the other is to transfer data with the split power amplifier.
RS-485 is a typical serial communication standard, which is widely used in the central control system. Its function is to facilitate the user to realize the interconnection between various intelligent devices. The two on the right are an external audio output interface and an external audio input interface. The output interface can transmit the sound signal of the host to an external device, such as a powered subwoofer, and the input interface can transmit a sound source signal such as a television to the host. .
There is also a TF card socket for expanding external storage, and the panel removal port makes the panel easy to replace.
Second, the installation steps
1. First remove the panel
2. Unscrew the four screws and remove the iron pieces on the back of the fuselage
3. Fix the removed iron piece to the bottom case.
The line that needs to be connected to the host is passed through the bottom box and connected to the host, and is usually preset in the wall in advance.
4. After connecting the wire, re-fix the fuselage on the iron piece, screw the screw and cover the upper panel (the bottom is schematic)

Connectors can be classified into three basic types: line to line, line to board and board to board. These three types of connections are not entirely different. There are two reasons for this type of overlap. First of all, the design of the same connector only needs to be redefined after slightly changing the connection mode, that is to say, it becomes a new design scheme that can be applied to another type of connection mode; secondly, a cable can be installed with a line to line connector at one end and a line to board connector at the other end during assembly, for example, the appearance of class 5 I / O connector is the most common one See for example. If we avoid the fuzziness of this kind of connection, it will provide an effective basis for connector classification.
