Abstract
Maximum load,terminal resistor and bias resistor are three main parameters of RS485 field bus,which directly influence the stability of the system.This paper adopts the current flow method to solve the theoretical value of bias resistor based on the equivalent circuit model of RS485 field bus,and further analyzes the influence on the maximum load and terminal resistor.The research result of-fers a theoretical basis for the application of RS485 filed bus and is very useful in many applications.关键词
