  • What dictionary did you use that contains the words "hv", "ckt" etc? Is there something seriously wrong with your keyboard, making it drop a lot of key presses? Or did you not have more time to spend on your request? How much time should people then spend on responding?

    We don't know what your circuit diagram looks like, so how would we be able to know if we can supply a circuit that is simpler?

    Have you spent any time reading the datasheets for the components used in the datasheet, and for reading up on RS-485? Knowing the hardware helps, and is sometimes a minimum requirement to be able to write programs that makes use of the hardware. Your goal was to write working software, wasn't it?
