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.
With the current development of banking, finance, securities, telecommunications, industrial control and other fields, serial port cards have played a huge role in the wide application of computer multi-user communication control systems. When we need to connect multiple serial devices, we will choose PCI multi-serial cards, which effectively solves the problem of insufficient serial ports in system integration and greatly reduces the cost of the project. However, many people tend to fall into certain misunderstandings when choosing.
We know that the usually computers only have 1-2 interfaces. Nowadays, computers with serial ports are not common, so multi-serial cards are needed, but usually they are multi-serial cards with PCI interfaces. In fact, some computers have only one serial port or no serial port at all, which requires a PCI multi-serial card to expand the number. If you have multiple serial devices that need to be connected, such as a serial mouse, IC card swiper, etc., this will not happen. The serial port is not enough.
The multi-serial port card is a device that can allocate multiple serial and parallel ports for terminal connection, and 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.
PCI multi-serial card is just as its name implies: a card that extends multiple serial ports from the PCI card slot. It is widely used in banking, finance, securities, telecommunications, industrial control and other fields. It is an important hardware component of computer multi-user communication control system. However, many people do not know how to choose correctly, and while spending more money, they also waste a lot of time. Here are some precautions I have summarized for you.
1. It is best to choose a big brand, as the product quality is relatively guaranteed. The well-known brands on the market include STC and so on.
2. The system has strong compatibility, otherwise you won’t be able to use it when you buy it back.
3. Product grade, choose according to the site environment: industrial grade, ordinary, economical.
4. Baud rate support, security and stability are also important.
STC has been committed to industrial Internet product research and development and industry solutions for sixteen years. The PCI multi-serial cards and PCI-E multi-serial cards it produces and develop are widely used in various fields. The editor believes that only by in-depth understanding of the products, when purchasing , in order to avoid certain misunderstandings, buy satisfactory products, spend the least money for the company, and achieve maximum profits.
