Fujitsu RAC & VRF to Modbus RTU (RS-485) gateway – full bi-directional monitoring & control, INMBSFGL001R000
IntesisBox INMBSFGL001R000 is an industrial communication gateway designed to integrate Fujitsu RAC and VRF air conditioning systems with Modbus RTU (RS-485 / EIA485) networks. The device enables both control and monitoring through Modbus registers, allowing HVAC functions to be managed from PLCs, SCADA or BMS as part of one consistent automation strategy.
The integration is fully bi-directional: you can adjust key parameters such as operating mode, fan speed and temperature setpoint, while also reading feedback required for diagnostics and supervision. On the Modbus side, the gateway can expose errors, alarms and selected internal variables, helping maintenance teams react faster and making it easier to implement alarm handling logic in the supervisory system.
The gateway is wired directly to the indoor unit, which supports stable communication and keeps installation straightforward. INMBSFGL001R000 can typically be installed and commissioned in a very short time—usually just wiring the gateway to the AC unit and setting parameters via DIP switches (configuration is also possible via Modbus RTU). No configuration software is required, and an external power supply is not needed in typical applications. A consistent Modbus register mapping used across this AC gateway family also helps reduce engineering time in repeat projects.
