I tried to use the 232 for an HR20 yesterday, but it wouldnt work. I had a Belkin adapter though and the mini to 232 cable wasnt a URC cable. So I dont know what the problem was. Also the model of the receiver was an HR20-100 instead of the HR20-700. Is there a difference in codes between models, or does Directuse the same 232 codes like they do IR codes?
