Dear Vladimir,

I took a closer look on the CI-CAM adapter from Technotrend.
There is a 3.3V voltage regulator (LM1117 DT 3.3V)

Similar, on the AD-SP400 it seems to be also a 3.3V voltage regulator (marked 1084-33PE). 
4046 board from Twinhan/Azurewave.

According to SMIT operation voltage for their modules is 4.5 to 5.5V

If in both cards the CAM takes power after these rectifiers 
you cannot have a guaranteed operation.

I think it's some kind of a driver bug because it begins working  
after  reinitialisation. Doesn't get hot. I have tried to call  
Aston as well  but with no success yet.

Dear Vladimir,

I read your post on linux-dvb list. We have an Aston Viaccess   
Professional 2.15 CAM .
I read that you also use Aston CAMS.  My question is whether your   
Aston Viaccess cam can descramble H264  feeds or not?
We have tried on a PACE HDTV receiver and a Tandberg unit and it   
does not descramble the H264 video pid. (black screen)
This does not happen with Viaccess RED cam.

On older Common interface adapters from Technotrend, the one for  
TT  Premium DVB-S card, there was a jumper for 3V or 5V cam  
operation.
I assume the new CI adapter does not have such jumper. If it  
still  exist maybe it will be a good idea to switch from one  
voltage to the  other.
Another solution is to test whether it works or not for Irdeto to   
use an Alphacrypt Classic CAM which, at least in theory,  
according  to MASCOM, supports Irdeto.
The third thing is to notice whether the SMIT cam gets hot in   
operation. If it gets too hot maybe a fan similar to the one for   
graphics card must be put near the Common interface adapter.

BTW. Do you have any e-mail address from Aston? I have tried to   
contact  them but there is no e-mail address in their website.

Best regards,
Dan Lita

Hello!

I'm using SMIT cams to descramble channels on TT S-1500 and TT-   
S2-3200. After some time of normal operation SMIT cams drop out   
and  stop decrypting the stream. It needs to be removed from the  
CI  slot  and reinserted to resume normal operation. Aston CAMs  
have no  such  problems, but they don't support 0x652 Irdeto.
I'm streaming with vlc. Tried many SMITs (Viaccess and Irdeto).   
Same  problem everywhere.

Regards,
Vladimir
