After talking to a few guys online, I found out about that input not from drac, and also found I was using the wrong pin on the pcm. I set the flag and swapped pins, thinking it was either gonna not work at all (wrong signal type) or read half what the pcm is expected. Mutch to my surprise, when I swapped pins and hooked up the laptop, it worked just fine and even read the correct speed!
