RS485 Connected to IP Gateway

It is a common practice to have one IP Gateway device in the network and a couple of other connected via RS485. In such case, the PC with the iSMA Configurator should be connected to the same network as the Gateway device and have the IP address in the same network segment. Make sure that the RS485 configuration parameters in the Gateway device are set accordingly, so that it is possible to discover the Modbus devices connected to the bus.
