The serial port control module , as the name suggests, is a controller that can realize control functions through the serial port. That is, the host computer sends instructions in a specific protocol format to the controller through the serial port to control peripheral equipment or devices, also called a single-chip serial port controller.
The serial port control module is a microcontroller controller with a serial port communication program written into it. It generally has two working modes:
1. Host computer monitoring mode: It can be controlled by the host computer’s serial port to realize serial port monitoring;
2. Offline control mode: After setting the relevant parameters through the host computer, it can also be controlled independently from the host computer.
The serial port control module is mainly composed of the following units: RS485 serial port, MCU (single chip microcomputer), input and output circuit (photoelectrically isolated digital I/O, analog module A/D), power circuit, etc.
The serial port control module can be used in both industrial and civilian applications. It has a wide range of applications and is suitable for centralized monitoring, remote monitoring, on-site data collection, remote control and other occasions.
The serial port control module of Zongheng Intelligent Control has the characteristics of easy operation, anti-interference, stable performance, powerful functions, economical and practical, etc. It is a high-performance, low-cost, easy-to-use solution for various switch (digital) and analog control. plan.
