Intesis® Modbus RTU – Fujitsu User Manual r1.3 EN 3 Quick Start Guide 1. Disconnect the air conditioning from Mains Power. 2. Attach the interface next to the AC indoor unit (wall mounting) following the instructions of the diagram below or install it inside the AC indoor unit (respect the safety instructions given). 3. Connect to CN65 between the interface and the AC indoor unit following the instructions of the diagram. 4. Connect the EIA-485 bus to the connector EIA485 of the interface. 5.

Intesis® Modbus RTU – Fujitsu User Manual r1.3 EN 4 Modbus Interface Specification Modbus physical layer INMBSFGL001I000 implements a Modbus RTU (Slave) interface, to be connected to an EIA-485 line. It performs 8N2 communication (8 data bits, no parity and 2 stop bit) with several available baud rates (2400 bps, 4800 bps, 9600 bps -default-, 19200 bps, 38400 bps, 57600 bps, 76800 bps and 115200 bps). It also supports 8N1 communication (8 data bits, no parity and 1 stop bit).

Intesis® Modbus RTU – Fujitsu o o o User Manual r1.3 EN This configuration is done via a Fujitsu remote controller connected to the indoor unit (Function number “42” – setting value “1” / operation of Thermosensor button) and must be done by Fujitsu authorized installers at the time of the installation of the AC. Register value after INMBSFGL001I000 startup is -32768, which means that no temperature reference is provided to the AC indoor unit.

Intesis® Modbus RTU – Fujitsu User Manual r1.3 EN EIA-485 bus. Termination resistors and Fail-Safe Biasing mechanism EIA-485 bus requires a 120Ω terminator resistor at each end of the bus to avoid signal reflections. To prevent fail status detected by the receivers, which are “listening” the bus, when all the transmitters’ outputs are in three-state (high impedance), it is also required a fail-safe biasing mechanism.
