Trio mc4n and Arduino RS485 communication
I want to communicate Trio MC4N_ECAT with Arduino via RS485.
I sent a data by following command:"MODBUS( 3, -1, VR(20),$2,1,1,1,205)".
but, I got improper data in Arduino Like this "FDFBFFFDFFFD2F3D".
I expected that the data must be similar to this: "1211CRC16".
please help me.
