I am working on a 10x10 ferrofluid matrix controlled by a video camera. I need to get a signal from my patch out to an 8bit parallel port. Can I convert the signal in max to 8 bit (ie. 10000001) and send it out through a cable like this?

I already have a circuit board to control my ferrofluid matrix, but I need a way to get the appropriate 8 bit signal out of Max.

I appreciate any help

Thanks
