Heya,

Anyone have any plans (or know where I can get one) for an optocoupler circuit for the parallel port to opto-isolate the PC from whatever you plug into the parallel port?

Thanks,
Mike

I do not know of any public domain schematics. However, you can purchase opto-coupled breakout boards designed for the purpose.

Do search for breakout board on this site.

One site is www.cnc4pc.com
