I had a lot of trouble getting it to work. I've tried using the Ethernet to RS485 conversion function that promises this, but it doesn't work if your end terminals aren't PCs. In addition, when they work, it happens for a short time, and then stops. Even customer support didn't understand why our setup (1 as a TCP server and the other as a TCP client) wasn't working. In the end I returned it and bought an expensive product to achieve my goal.
