WiFi Twin hw 2.6 with UW2.28: Keys Update ? Configuration ? Settings ?

Hi,
I'm a newbie in Diablo Cam & have some questions.
I need some help
Can you describe where to place these update.rar files in the cam by using CIS983 to Diablo WiFi Twin HW 2.6?
Link ist nicht mehr aktiv.

In this update.rar file there are 2 folders

1- CAIDS
2- Latest KEYS & MAIN CaID for Fausto-Diablo [All EMU Firmwares] Inside this folder

- I've copied all of the .XML files in the CAIDS folder to Diablo Cam by CIS983 > CAM:\CONFIG\CAIDS
There is no problem with that.

But here is the tricky part...

- Inside the second folder named "Latest KEYS & MAIN CaID for Fausto-Diablo [All EMU Firmwares] Inside this folder" there are;

CAIDS.XML
Fausto_CAIDS.TXT
Fausto_Control_Word.TXT
Fausto_Idents_List.TXT
Fausto_Keys.TXT
Fausto_Softcam.key
*KEYS.BIN
KEYS.XML
MAIN.XML

Where should I copy those files ?

Should I copy all of them in to the CAM:\CONFIG\CAIDS again ?

Also, in original UW2.28 Diablo there is a KEYS.BIN and DATA.BIN in the Diablo's CAM: folder.
CONFIG (folder)
MENU (folder)
PLUGIN (folder)
EMU (folder)
* KEYS.BIN
* DATA.BIN

Should I replace the KEYS.BIN in the root folder of Diablo CAM: with the KEYS.BIN file in the update.rar ???

What about DATA.BIN in the :CAM ?
Should it stay there or should I have to erase it ?

I may be talking nonsense but I need some basic & direct description.

Finally what about the Menu Screens in the Diablo after placing it in the CI module of the TV ?
I made the recommended settings...
CAIDS [MAIN]
AutoPMT [OFF]
* N2 AU [OFF]
EMM [ON]
EMU [ON]
Fixed CW [ON]

1- There is NO setting as N2 AU in the menu screens of the Diablo WiFi Twin hw2.6 with UW2.28 ?

2- What about the CAS settings ?
SECA
CRYPTO
NAGRA2 etc..etc..?
Should they be [ON] or [OFF] ???

I will be very happy if you can help me... Thanks in advance
