Convert, extend transmission distance or isolate serial data. These small devices convert between RS-232 and RS-422/485 protocols. Options include port or self powered, screw terminals, DB9 or DB25 connectors, isolation and LEDs to indicate data flow. The converters, extenders and isolators function as an extension of the computers built-in serial ports, so no software drivers are necessary. Surge protectors protect data lines from transient voltage spikes which are common in industrial environments.
