NPort serial device servers connect serial-based industrial equipment to Ethernet networks. It enables remote access to PLCs, meters, sensors, and other critical devices across industrial environments. This approach helps organizations extend the usability of existing serial infrastructure while improving accessibility and network integration. The NPort G2 Series also supports modern OT requirements related to cybersecurity, compliance, and operational efficiency.
