WebFeb 20, 2011 · But the standard RS485 bus signal can't be AC coupled, because it's not a DC balanced signal, it has a dedicated idle level, and the duty cycle of character frames varies between 10 and 90%. Even more problematic, you can't couple an AC signal to the power lines without decoupling the low impedance DC path for AC, e.g. by chokes.
