In this issue, the editor will bring you what problems you need to pay attention to when using the serial server. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

The serial port server is the Internet of things equipment that converts the serial port into the network TCP/IP signal, and it is the converter for data conversion between the RJ45 network port and the serial port. Serial port servers basically have the function of transparent transmission, of course, it does not rule out that serial port servers with one-way serial port can use different usage modes in different programs.

For example, there are RS485 to Ethernet and RS232 to Ethernet in serial port to Ethernet, or to wifi signal through Ethernet, usually using serial port server with WIFI function, this serial port server can realize serial port to WIFI signal, and WIFI to RS232 / RS485 serial port data can be converted.

If you need to use the Modbus protocol, you can choose a series of industrial products of human technology, which can support polling mechanism and transparent transmission of data between Modbus RTU and TCP. What problems need to be paid attention to when setting up a serial server?

The main reason is that we need to pay attention to some problems when choosing the mode of connection.

1. Ethernet connection mode: connect the serial device to Ethernet through the serial server, just connect the serial server to the hub or switch. By setting the IP address of the serial server, the serial server can become a node on Ethernet. Serial port server numerical control system is connected to Ethernet, through the network, different devices and different forms of serial port (RS232/485/422) can be connected to Ethernet to achieve heterogeneous networking. Networking allows the entire company to connect devices to the network. In the process of networking, in addition to using industrial routers and industrial computer expansion, we can also use industrial wifi serial port server for expansion. Some technology can provide different network ports, different functional requirements of the WIFI serial port server for everyone to choose from.

two。 Local area network direct connection mode: the so-called direct connection refers to the network cable port of the computer and the Ethernet port directly connected to the serial server. The network routing is simple and can achieve longer distance transmission. Because of the increase of the distance between the computer and the serial server, the longer transmission is realized. If the serial port is set to RS422 or RS485, it can also be mapped to different ports. In this way, for the host, no matter what interface operation is connected to the serial server, it is the same, which greatly simplifies the host compiled into the workload.

The above is the editor for you to share the use of serial servers need to pay attention to what are the problems, if there happen to be similar doubts, you might as well refer to the above analysis to understand.
