That's what I thought too.

PIN    STATE     state

 1      1          0
 2      0          0
 3      0          0
 4      0          0
 5      0          0
 6      0          0
 7      0          0
 8      0          1

       255        1

So just changing pin state would alter the output.

I am guessing that by a binary number you mean an output in binary
format, like '01010101'?
