Babel Buster SP-GW is a transparent gateway for mapping Modbus RTU devices to Modbus TCP and vice versa. All requests received from an RS-485 master are passed straight through to Ethernet servers. When configured to go the other way, all requests received from an Ethernet client are passed straight through to RS-485 slaves.
