What is a serial port server - application and operation

Serial port server, what is it?

Serial port server is a well-known network that transmits data. It is used to connect the Ethernet, LAN and serial (COM) port of a computer. The main purpose of serial port servers is to be able to be used with serial devices such as printers, appliances or climate control systems on a network that do not include only the computer's serial port for connection. Access an external serial device to a network and access to any location. Serial Port Server is a server that supports an Ethernet device and the device can be a serial device for network use. For example, you can run old carrier printers that are only when connected to the COM port of the computer to the network printer, and this can be controlled from anywhere by the corresponding serial port server, the serial port server is connected to the network via Ethernet. this effect can only be through the serial server and virtual serial port, which simulates the PC port and the device that is seemingly connected to the port.

How does the serial port server work

On the one hand, it can be said that a serial port server is a very simple application, as it does not have to provide any particular security, but only connects the serial device to the network. On the other hand, it can be said that it is a device that allows you to control many functions, Ethernet switches and routers. Devices without security or authentication are basic, for data and access to serial devices without security oversight, such as local office sources with printer access. In the same place, a more complex serial port server with enhanced and authenticated multiple devices where security is important. Wide applications include in remote key system, environmental control system, plant control mechanisms and other industrial applications where security is critical. Use with serial port server models, you can connect to simple printers, screen switches, robot assembly machines, medical equipment, sensors and other industrial switches.

Application of serial port servers- examples

Serial port server has a wide range of applications, such as unattended weighing, remote access, access control gateway, etc. used used with industrial router or industrial switch.

Fire alarm application:connect a serial port server to the RS232/485 serial port that contains fire alarms to quickly share alarm information to the cloud platform and notify personnel to eliminate the hazard.

Intelligent light sources factories and mines:original industrial and industrial lighting devices to "Power Control Lamps", which cannot be connected to appliances and mechanical devices, resulting in energy waste. Network communication between serial servers and serial lighting ports can not only enable lighting control, but also the functional functions of equipment appliances and devices that affect the cost caused by electrical equipment.

Monitoring of tap water supply:at present, the water supply system of waterworks is still subject to network communication of the serial port, which is only responsible for machine operations, with limited transmission distance and difficult system maintenance.  Serial port server can monitor the status of water equipment in real time through TCP server mode.
