Serial server

(also serial device server, terminal server)

Serial server definition

A serial server is a networking apparatus that facilitates interactions between serial devices and various other equipment, like computers or additional network components, across an Ethernet network. Serial servers are frequently employed for the remote administration, supervision, or regulation of equipment based on serial communication, enabling users to exchange data from serial devices with computers and other connected systems needing a direct link.

Serial server examples

  • RS-232 Serial server: A type of serial server that supports RS-232 serial communication, commonly used to connect devices such as modems, printers, and barcode scanners.
  • RS-485 Serial server: A serial server that supports RS-485 communication, which allows for longer cable distances and is often used in industrial automation and control systems.
  • USB Serial server: A server that connects USB-based devices to an Ethernet network, allowing them to communicate with other networked devices.

Comparing serial servers to other solutions

Serial-to-Ethernet converters are similar to serial servers, but they typically lack advanced features and management capabilities. Serial servers offer more robust options for device configuration, security, and monitoring, while providing remote access to serial devices across networks.

Advantages of using serial servers

  • Remote access to serial devices without direct connection.
  • Easy integration of legacy equipment into modern networks.
  • Centralized management and monitoring of serial devices.
  • Enhanced security and access control.

Tips for using serial servers

  • Choose a serial server with the appropriate number of serial ports and communication protocol for your devices.
  • Implement security measures such as data encryption, user authentication, and access control.
  • Regularly update the firmware and software of your serial server to ensure optimal performance and security.
