First Real Project Help

I went to Programmer 1 months ago and have slept many times since. So my knowledge has rusted shut. So I am trying to interact with a dvx and serial port 4 on it. I am controlling a Denon DN-500BD. I can't find a module so was planning on writing controls for it. My problem is I can't seem to get it to respond. Below is some information I have setup. I have even shorted pins 2 and 3 to see if I could get any information back from the port and have had zero luck. I am guessing I am missing something obvious but tired of pulling out what little hair I have. Any help would be appreciated.

Thanks
Thom
