Why Does Serial Communication Still Matter?
Despite the rise of Ethernet and wireless standards, serial ports remain widely used in industrial automation, transport and utilities. They provide dependable point-to-point links with low overhead, making them ideal for equipment that needs simple, continuous data exchange.

Which Products Support Serial Networks?
This category includes device servers that bring serial equipment onto IP networks, converters that adapt between RS-232, RS-422 and RS-485, and repeaters that extend communication distance. Surge protectors are also available to safeguard systems against electrical spikes.

How Does Industrial-Grade Hardware Differ?
Compared to consumer-grade adapters, industrial serial devices use reinforced housings, extended temperature components and isolation features that protect both the converter and connected equipment. This ensures reliability for UK projects expected to run without interruption for many years.
