Moxa NPort 5450I , RS-232/422/485, with isolation

Moxa NPort 5400 Series – 4-Port RS-232/422/485 Serial Device Servers for Serial-to-Ethernet Communication

The Moxa NPort 5400 Series provides an efficient solution for connecting up to four serial devices to an Ethernet network. Featuring independent operation modes per port, an intuitive LCD configuration panel, 2 kV isolation on select models, and robust security support, these device servers are ideal for industrial automation and remote device management applications.

Each serial port can function independently in different modes such as TCP server, client, or Real COM, maximizing deployment flexibility. Standard models include an onboard LCD screen for quick IP setup and configuration, eliminating the need for console access.
