Industrial serial-to-Ethernet gateway

The USR-N540 converts RS232, RS485 and RS422 signals to TCP/IP over RJ45, letting legacy PLCs, meters and sensors join a modern network without rewriting firmware. Engineers commissioning SCADA or building-automation systems can bridge serial field devices to Ethernet infrastructure in a single compact module.

Multi-protocol flexibility for mixed installations

One unit handles three serial standards simultaneously, so a site running a mix of 232, 422 and 485 equipment needs only this converter instead of separate adapters. The 540 model’s combined interface reduces cabinet space and simplifies wiring for integrators managing heterogeneous serial networks.

Preguntas sobre este artículo

Will the RS-232, RS-485 or RS-422 serial ports on the USR-N540 require any periodic maintenance or replacement?

The serial ports are solid-state interfaces with no moving parts or consumable components, so they do not require scheduled maintenance or replacement under normal operation.

What is the first limit reached when the USR-N540 runs continuously at high data rates?

Sustained high throughput will hit the Ethernet bandwidth ceiling before the serial interfaces become a bottleneck.
