I'm a new in this area. Just bought that model, and completely confused :
1. the model has USB 2.0 and RS232 ports, but the manual says that to upgrade the software, use the later. Is there a problem if I use the USB one ?
2. can I use the keys bin, as posted on the first sticky of this forum ? I mean, are those keys bin are for ALL humax model ? Some of them are for 5400 ?!
3. move to the second sticky, again, can I use / upload the emu using ToH34_Hotxxx.zip ? Are they specific humax model ?
4. some emu support the 'auto-update'. Is there one for this model ?
5. what are this setting posted by GioppyGio or Cyrus Team ?

Thanks for your help.
