How Do Serial Device Servers Extend Equipment Life?
They allow legacy machines with RS-232, RS-422 or RS-485 ports to be connected to modern IP networks. This avoids costly upgrades and keeps existing hardware in service while still benefiting from centralised control and monitoring.

Where Are They Typically Installed?
Serial device servers are used in factory automation, building management and energy networks. They make it possible to monitor sensors, controllers and meters across large sites without rewiring or replacing older devices.

What Features Make Them Suitable for Industry?
Models in this range include DIN-rail mounting options, wide power inputs and extended temperature ratings. Many also support encryption and secure management, ensuring data from critical systems is protected as it moves onto the network.
