    Hi Everyone !

    I have an IR LED, phototransistor, max 232 and RS232. Actually, i try to make the connections of these. First of all, I know that I should use an ADC before max232.(I am right ?). I need to use ADC for phototransistor. But, I consider that for IR LED, should I use DAC after RS232's output ?

    As a result, can anybody help to establish the exact circuit ? :/

    Predicted circuit schematic is attached. Let' s make it work :)

    RS232 word has a particular format, how do you intend transmitting a photo transistor source this way?

    Why do you want to use MAX232?
    What are you sending the data to?
