Serial Terminal Servers

Transmit Serial over IP Ethernet

Terminal Server Network Diagram

Terminal Server Network Diagram

Terminal Server Network Diagram

A Terminal Server, also known as Serial Server, connects devices with a USB, RS232, RS422, or RS485 serial interface to a local area network for transmission of serial data over Ethernet to network server applications. The most common application for Terminal Servers is out-of-band management of routers, switches, and firewalls as an efficient way to recover equipment when the network is down. It serves as a single hardware solution for a secure alternate route to monitor IT, networking, security, and power devices from multiple vendors. Terminal Servers have physical wired or wireless (LTE or WiFi) network connection on one side, and one or more serial ports on the other side. While some Serial Terminal Servers can be very simple devices, it is best practice to use a Terminal Server with advanced security functionality, data encryption, and user authentication to ensure network data transmissions, and access to network equipment, is protected.
