Command >
Install a Pro:Idiom Key
The Pro:Idiom encrypter built into the HCS7720 contains a default encryption key. When first
installed, the HCS7720 will use this key to encrypt content. This command enables you to
change the encryption key, if necessary.
Note: In order for a Pro:Idiom encrypted channel to be displayed, the receiver
must contain a Pro:Idiom decrypter, and the receiver must be configured to allow
decryption of the desired channel.
Note: The process of updating the encryption key will synchronize the decryption
key in any receiver tuned to this card's output. If the target receiver is turned off or
viewing a different card, the synchronization will not occur, and the output will be
scrambled. Ensure that all encrypters and decrypters in a system are synchronized
to the same key.
1. Confirm the directory location of the Pro:Idiom key (.hex) file.
2. Connect a PC to the HCS7720 Service Port, and access the Main Menu as described on
the previous page.
3. At the Main Menu Command > prompt, type the menu command that corresponds to the
Install PI Key option and press Enter.
4. At the Setup PI key. Continue (y/n)? prompt, type y and press Enter to
continue.
5. The system will request a key file. Transfer the new Pro:Idiom key file using Xmodem
protocol.
For example, in HyperTerminal, select Transfer and then Send File.... In the Send File
window, enter or select the appropriate Pro:Idiom key file in the Filename field, and select
Xmodem in the Protocol field.
The system will print out the result of the update process. Note that the new key will be stored
in non-volatile storage regardless of process results.
