USR-N540 - 4-port Serial to Ethernet - PUSR

4-Port Ethernet Serial Converter

The PUSR USR-N540 is a 4-port serial-to-Ethernet converter, designed to connect multiple RS232, RS485, or RS422 devices to an IP network. It centralizes serial communications in industrial architectures and supervisory systems.

Four Independent Serial Ports

Each serial port can be configured independently, facilitating the integration of heterogeneous equipment with different parameters. The USR-N540 is suitable for installations where multiple PLCs, meters, sensors, or serial systems need to be connected to the network.

Modbus and IP Communication

The converter supports serial communication over IP, TCP/UDP modes, and the Modbus TCP to RTU gateway function. It can operate in master or slave architectures depending on system requirements.

Industrial Design

With an operating range of -40 °C to +85 °C, the USR-N540 is suitable for industrial environments. It simplifies remote supervision and maintenance of serial equipment.

Applications

The USR-N540 is suitable for SCADA systems, automation, payment terminals, access control, industrial measurement, and the integration of multiple serial devices.
