psc serial mode

I am trying to use the Parallax Servo Controller (PSC) with a device that only sends inverted data, which is a problem because the PSC apparently only understands true data.· How can I convert inverted data so the PSC can understand it?·

Also, do I need to do anything special to my hardware because the PSC is open - drain?

thanks

    Not quite sure what you are after here. What device is sending inverted data?
    If you want to invert 1' & 0's you can use a 7404 NOT gate.

    It's a 5 volt signal coming out of the serial port of a flashlight 186 computer.·· I know it's inverted (as in True/Inverted) because when I have it talking to a stamp, they understand each other if I set the stamp baudmode to inverted and they don't understand each other if I set it to True.
