The use of industrial Ethernet has become very widespread in modern factories. In today's modern industry, which is fully moving towards informatization, more users are using industrial Ethernet for information transmission, completing more integrated industrial automation and informatization solutions. Modern industry is also developing towards a more intelligent direction under the promotion of industrial Ethernet.
　　
In recent years, with the continuous maturity and development of industrial Ethernet, the application of serial port device networking servers has become very common. Choosing high-performance serial port device networking servers is a convenient and advantageous condition for industrial production. Currently, there are many serial port server suppliers, among which MOXA is a brand that produces such products.

Today, the editor recommends several serial servers represented by Beijing Tonglian Era Electronics for your reference:
　　

MOXANPORT51301 port RS-422/485 serial port device networking server
　　
In most applications, long-distance data collection is achieved using RS-485 daisy chain, but reading data from each device takes a relatively long time. To improve this situation, NPort5130 can help the computer send commands to each RS-485 device and receive the returned data within one second without waiting for a round robin.
　　
Easy to install. Perhaps the NPort5130 you are using is distributed in different locations on the network, but they have the same configuration. To avoid duplicate installations, Moxa provides a convenient batch installation tool in NPortAdministrator for Windows. Users can configure all parameters except for IP by selecting all online NPorts.
　　
Troubleshooting is easier with NPort 5130 supporting SNMP V2.0. By using SNMP Manager, users can observe the status of all NPort5130 on the network. When NPort5130 encounters an error (user-defined), it will automatically notify the SNPManager. In addition, the device also provides alarm functions for users who are unwilling to use SNMP manager. Through Moxa's Windows Utility or webconsole, users can customize alarm triggering conditions. The alarms received by users include information such as hot start, cold start, or password change of NPort5130.
