I think the card will work with your TechnoTrend receiver, but you need a different CAM.
A CAM is an own little computer with its own little menu. So it's possible that the CAM can read some data (keys, card number, IKE?) from the inserted card. However, that still doesn't mean that CAM and card work together, so you could watch TV.
You have to find the right CAM for your card. Normally CAM and card work together without any setup or menu diving. Ask the people, who gave you the card, which CAM you should use with it. Here in Germany it's possible to buy or rent a CAM. Maybe you also have those options in Yemen.
Thank you for your responsiveness and for your patience in dealing with my inquiries.
