AC800F /SD802F EI803F/ - FL 2013 SP1 RU1 EPROM downgrade to FL v9.2
As few times before I would like to ask you for help. Again.
As I marked in the subject of the question I need to downgrade AC800F /SD802F EI803F/ from EPROM version FL 2013 SP1 to FL v9.2.
Product : Control Builder F
Version : 9.2.7572 SP1
Date : Do Dez 02, 2010 21:27:37

instaled on Win7 Ultimate SP1 EN. And it's connected, pinging and yesterday I was able to load to this PS project configured in FL2013 /it was installed on the same machine before/.
During the EPROM loading I can see programing window with status bar... and both run/top and Prim/Sec diodes orange blinking on AC800F... but after couple of seconds loading fails with message: "EPROM download failed: Conection to station could not be established"
I know, that during firmware upgrade for some of the version of FL and PS it's important to first load EPROM to some "middle version". Is it the same in this case?
What is the rason and how to solve that problem? I would be grateful for any hints.
