    1.1. Overview The USR-N5X0 Series are network-based serial device servers that connect RS-232/422/485 serial devices, such as PLC, meters, sensors, weigh scale, barcode scanner, card reader and serial printer directly to a TCP/IP network. Data coming from the Ethernet port is sent to the designated RS-232/RS-422/RS-485 port, and data received from RS-232/RS-422/RS-485 port is sent to the Ethernet port, allowing bi-directional communication.
