What Problem Do Converters Solve?
They bridge modern USB-only PCs with older RS-232, RS-422 or RS-485 equipment. This avoids replacing legacy devices while still enabling them to connect to new systems.

Who Uses USB to Serial Converters?
Engineers in automation, utilities and transport rely on them to maintain communication with long-serving controllers and meters. They provide a simple, portable link between old and new.

Why Select Industrial-Grade Models?
Compared to consumer adaptors, industrial converters include stronger isolation, DIN-rail mounts and extended temperature ratings. This makes them dependable in demanding UK projects where longevity matters.
