This is how I use Channel Master for channel editing for those that want to use it:
Fully boot reciever ON until you get channel #
Open Channel Master. Go to TOOLs and read from STB. Set Top Box Type: Pansat 2700A,Pansat 3500s. Click Next, Next again after entering right com settings and Next again. It will read STB ,then make your changes and save bin. Then go tools , write to STB. Set Top Box Type:Pansat 2700A,Pansat3500s . Click next,next at com settings, then next again and it will write to STB, then reboot itself to new channel list.
Key is to choose Pansat 2700A,Pansat3500s as box type and to have reciever fully booted up before reading or writing to your reciever using Channel Master.
