1. Wrong forum. This should be posted in the Home Theater forums.
2. You can't just plug a receiver in and have it work. It has to be activated or provisioned by the service provider. Assuming that the receiver is compatible with the provider you choose to use, you will need to talk to their customer service and provide them with the devices serial number (or other ID depending on what they require) in order for it to work. You can't just put up a dish, connect a box, and start receiving broadcasts.
