The Moxa NPort 5100 Series offers a highly compact and cost-effective solution for connecting legacy serial devices—such as card readers or POS terminals—to modern Ethernet networks. With support for RS-232, RS-422, and RS-485, these 1-port serial device servers ensure seamless communication over TCP/IP and are ideal for industrial and commercial applications.

They are easy to install, support multiple operating modes (TCP Server/Client, UDP, Pair Connection), and include Real COM and TTY drivers for Windows, Linux, and macOS. Optional jumper-configurable pull-up/down and termination resistors ensure signal integrity for RS-485 environments.
