The WB-MGE v.3 gateway is designed to connect devices with RS‑485 and WBIO (I/O modules) interfaces over Ethernet and Wi‑Fi.
Modbus RTU gateway
— Modbus TCP ⇄ Modbus RTU conversion, up to 8 clients per port.
Transparent mode
— any protocol over RS‑485 (Modbus RTU, DOOYA, AKKO and so on) is passed through as-is.
Sniffer and master emulator
— real-time decoding of the bus exchange and manual request sending.
Caching multimaster
— non-invasive data collection from someone else's line, served through a separate Modbus TCP server.
Repeater
— relaying between the RS‑485 ports: range extension, branching, noise isolation.
Transmission disable (TX)
— receive-only mode for a safe connection to a live system.
WBIO modules connect via the side I/O Bus connector and are exposed as a Modbus device on the RS485‑2 bus with an address printed on the module label. WBIO support can be disabled in the web interface to free the port for any protocols.
