I just finished udating my DSP and firmware on my late (got it 04/20) Malaysian
-SC885P with original main 1.06 and old DSP1 firmware.
1.DSP i set my Sony changer to 48kHz PCM and updated without difficulty. It would not stop, so i replayed the track which resulted in prompt reinstallation over the already done install. Stopped and waited 15 min the restarted. The right DSP1 version is showing.
2. Used a RadioShack 6 ft RS232S straight through male-female cable from my HTPC. No problem.
TIP: lost one whole day because of two things. One, the COM1 driver was modified (Elo touchpad), so i deleted all drivers and restarted computer. Only two drivers should show one "Microsoft......" the other one "Serenum...".
Two, i was using the wrong cable, a female-female with two sided short male-male adapter to the Onkyo. Only straight (1-1,2-2,3-3, etc. pin correspondence) male-female cables should be used !
Luckily i can return the USB-serial cable and drivers that i also purchased for the worst eventuality.
My advice is read the instructions carefully and do it on a morning after you slept all night, no Heineken or Hennessy V.S.O.P. in the system
If at any step you run into snags just log on to AVS and search.
I bow before you Gurkey and the brave beta testers who pioneered this path. Many thanks!
Onkyo received an angry email with a link to this forum, i cannot even register my unit on the Onkyo site, had to do it on the Integra site as a 9.8 with last digit from serial missing (showed purchase date 3 months earlier, dammit).
Al Jarreau has an SACD with an interpretation of Route 66 where i could hear some kind of train in the background on my Yamaha. Now, i hear the train crossing the stage and the bells too, all this while Al is singing on. Wait until i calibrate you baby!
