The Phoenix Contact family of serial device servers and gateways provides a simple way to migrate legacy serial devices and buses to modern Ethernet networks.

Serial device servers or terminal servers enable you to connect devices with an RS-232, RS-422, or RS-485 serial interface to a local area network (LAN). Device servers allow serial PLCs to interface to with laptops over Ethernet.

A gateway is used to convert the protocol of one device to the protocol suitable for the other device or tools to achieve the interoperability. The most common industrial protocols are supported with various combinations of RAW/ASCII serial data, Modbus RTU, TCP/IP, Modbus TCP, and EtherNet/IP™ technology.
