Therefore, this paper proposed a scheme to extends extend the meter auxiliary terminal function of the acquisition terminal RS-485 meter auxiliary terminal function, to realize so that the RS-485 meter reading port would serve as for the acquisition terminal local communication port, and implement the functions of open the R
