Note
In addition to the conventional RS485 control, users can also use N4RFA04 with RT5BF01 wireless transmission module for data transmission without laying too many and too long signal transmission lines. The N4RFA04 module only needs to be powered on to realize remote control. It is very convenient for users to remotely operate N4RFA04 equipment, effectively avoid , broken line, poor , etc. of the signal line, and also very convenient for users to operate N4RFA04 from a remote place.
