The buzzer is a kind of electronic component that will make a squeaking sound. We will install a buzzer in the general matrix switcher HDMI, DVI, VGA, AV and hybrid matrix switcher, then his What is the role? Today, Guangzhou Ou Yali Information Technology Co., Ltd. introduces his practical functions for everyone!
1. When debugging the matrix switcher, we can use the matrix switcher. When engineers usually use computer software or use the central control system to control the matrix, he may not be next to the matrix switcher, then you can use the matrix switcher. Whether the command is received or not, you can judge whether the control wiring of the matrix is ​​normal or not.
2. Prevent keystrokes during matrix operation. We will make a buzzer every time we press a button. This will ensure that every button check is normal, and whether we press a button during this operation. Buttons can effectively solve the probability of error
3, some specific functions can use some high-definition matrix such as HDMI, DVI, he needs to read EDID information, or seamlessly mix the card matrix to set the resolution and so on, we can follow the action of some of our specific buttons , press and hold some buttons to judge whether the operation is correct by the sound of the buzzer
4. When checking whether the matrix is ​​damaged, we can use the network or the central control to control the matrix during the debugging process. The customer may feel that their wiring and software are no problem, then the matrix has no image input and output. We can judge according to whether the buzzer has received the command from his central control system or computer software.
Can the buzzer be turned off? Answer: The buzzer of the matrix switcher can be turned off. It can be turned off and on directly through the buttons on the front panel. Generally, the engineers can turn off the buzzer after debugging the device.
