Serial Port Board

The serial port board screen is a TFT color LCD display control module with serial communication, which can be connected to external devices such as PLC, invert-er, temperature control instrument, data acquisition module etc. The unit writes parameters or inputs operation instructions, thereby realizing the information interaction between the user and the machine.


On the market, the serial port board interface screen of the early version before 2010 are simply downloaded through a host computer software, and then send commands to display various interfaces that need to be displayed, so as to achieve the required display effect. Only upload coordinates are supported.

In the version developed in 2014, the serial port board has formed an industrial chain, and the serial port board screen has very powerful functions such as some serial port board have configuration functions, and various functions are no longer simple and rough operations using images. The interface operation is getting closer and closer to the LCD display of some smart phones.
