As the earliest communication method between electronic equipment and computers and electronic equipment, the RS-232 serial port is now widely used in the field of industrial control. The RS-485 bus is used to make up for the short communication distance of RS-232 serial port communication technology and can only support point-to-point data. Communication technology resulting from communication and other shortcomings is also widely used in the field of industrial control.

The Function and use of PCI and PCIe serial port card (Source: www.stc-cable.com)
We know that a multi-serial port card is a device that can allocate multiple serial ports for a terminal connection. Each terminal can communicate with the host through it. Using a multi-user card is the most convenient and simple solution to expand the number of computer peripheral devices. It allows the computer to easily expand the serial port or parallel port, so it is also called a serial and parallel port expansion card.

The serial port card is also called a communication card, which allows the connecting terminal to communicate with the computer, The serial port card requires no software development and is plug-and-play. It protects the serial port of the host so that the host can connect to more terminals.
