I got my old Pansat 2550>2700 PUFF working by loading the necessary bins. Scanned and, with your help, got all the channels working. So far so good.
Now I'm trying to download the list of channels onto my computer using Channel Master but the damned thing won't read by STB. What could the problem be?
Like I said, my cable worked fine loading the bins so it's not the cable and I've tried using my Desktop and the laptop so it's not my Com Port.
Use the same cable (straight RS232) as you use on your receiver. However, when "Channel Master" asks you the name of the receiver, say it is "2700 or 3500" . Always have the receiver in full "ON" position showing a channel number whether you are uploading or downloading a list.
