## Frequently asked questions

**I need to create an Ethernet tunnel to carry RS485 from one point to another. How can I do it?**
A pair of this product can be configured to establish the TCP or UDP tunnel and transparently send RS485 signals received on the serial port from one side to the other. The TCP configuration involves setting a device as a TCP server, specifying a listening port, and a device as a TCP client, indicating the server's IP address and port. In the UDP configuration, however, both devices must be set with the IP and port listening to the counterpart. As a last step, the serial parameters (baudrate, databits, stopbits and parity) must be correctly configured.
