How to choose Serial Device Server

As an IoT communication device that realizes the serial port to Internet function, the serial device server is often used in networked projects for data acquisition and remote control, and is widely used in the fields of gate switches, computer room monitoring, and PLC industrial equipment. Using it without development, you can easily realize the two-way transparent data transmission between RS232/485/422 serial port and TCP/IP network interface, connect the network for data communication, save manpower, material resources and development time.

If you need to buy a serial device server to achieve the above functions, but do not know how to choose a serial device server that suits you, you can consider the following aspects.

1Application environment

If you plan to use the serial device server in outdoor scenarios, the complex and even extreme working environment will bring great challenges to the normal operation of the serial server. For example, smart transportation solutions are basically installed on highways or roads. Under extreme weather conditions such as temperature and humidi///ty, the operating temperature and humidity range and hardware protection performance of the serial server should be considered.

2Product quality

  1. Stability: Stability is the core factor of the quality of serial device server. In many industrial sites, the power supply voltage fluctuates greatly, which will easily damage the equipment and cause economic losses. Therefore, a serial device server that supports wide voltage power supply, power supply anti-reverse connection, and electrostatic protection will be the best choice. For industrial application scenarios such as data acquisition, the stability of data transmission is very important, and data acquisition is not timely, data loss and other problems, so it is best to choose an optimized TCP/IP protocol stack when purchasing, the technology is mature, stable and reliable, and fast implementation Serial device server for bidirectional transparent transmission of data.
  2. Security: Communication security in data transmission involves privacy, confidentiality and other issues, and its importance is self-evident. A good network security system will greatly reduce security issues such as leaks during enterprise operations. Excellent serial servers usually use IoT communication gateways with communication encryption algorithms, double-layer watchdogs and other keep-alive mechanisms to achieve multiple protections.
  3. Convenience: The configuration of the serial port server is difficult for non-professionals, because it is best to choose a product with convenient configuration. The current prominent serial server can realize the protocol conversion inside the server. Users don’t need to care about the specific details, they can simply set through the internal web page of the server, or use the setting software to set, and the setting will be permanently saved.

3Interface selection

Usually the serial device port specifications of the serial port server are RS232/485/422. When purchasing, you only need to check the specific interface required by your project and select the serial device port to Ethernet converter with different serial port numbers.

 

Using the above three criteria can help you determine the serial server you really need. USR IOT's Ethernet converters has the advantages of mature technology, stability and reliability, especially the Industrial Serial to Ethernet Converters, which includes different models such as 1, 2, 4, and 8 port serial-over-Ethernet options.
