Frequently Asked Questions

What voltage levels does the USR-TCP232-T2 support?

The module accepts a DC supply of either 3.3 V or 5 V and uses TTL-level signals (0–VDD) for its UART interface. Ensure your host microcontroller’s logic levels match the chosen supply.

How do I configure the network settings on this converter?

Connect to the module’s default IP address via a web browser (see user manual for the exact default address). Use the on-screen web interface to assign a static IP or enable DHCP, set TCP/UDP port parameters, and save your configuration.

Is the module protected against electrical interference?

Yes. The USR-TCP232-T2 includes built-in 2 kV electromagnetic isolation between the Ethernet side and the serial/power side, enhancing reliability in industrial environments.
