Hitachi air conditioner control via Intesis Box via RS485 interface with LM5

[d25m07y1993]

I am using the LM5 incorporating the HI-RC-MBS-1 Intesis Box for control Hitachi air conditioner.

My air conditioner code is RAS ...


And it is communicating with each other via RS485 protocol, I have tried many ways but still not done.

If someone has done this please give me some information for me to accomplish this.

I thank you very much.

HI-RC-MBS-1 uses Modbus RTU, so the easiest way is to create a profile (docs: http://openrb.com/docs/modbus.htm). Start by configuring RTU settings in Modbus tab then use RTU read test to check communication between LM and Intesis device.
