  • Hi,

    I' ve a rs232-4/20 mA converter but I need to invert the signal logic level on the rs232 side because the current loop circuit uses the following rule: 4mA = low logic level - 20 mA High logic level. By my understanding your rs232shifter invert the logic signal levels but move to a voltage between 0 to Vdc. My curent loop link speed is 9600 bps but i could decrease a little bit, could you please suggest to me a circuit (integrated or not) with the components to be used to invert the logic level using rs232 signal voltage level in such way put that circuit between my pc and the rs232/currentLoop converter ?

    Thanks :-)
