Decoder names are limited to 15 characters in length or less. Decoders are automatically
authorized when they are added to the list.
5.
Repeat for all required decoders.
C.8.3.3 Delete IRDs from the Conditional Access List
6.
Type tca delete <decoder name> and press Enter.
C.8.3.4 Enable Individual IRDs
An enabled, or authorized, decoder will be able to unscramble the incoming transmission from the
encoder.
8.
Type tca auth <decoder name> and press Enter.
9.
Repeat for all required decoders.
C.8.3.5 Disable Individual IRDs
A disabled, or deauthorized, encoder will not be able to unscramble the incoming transmission
from the encoder.

C.8.3.6 SE4000 is Now Processing Using the Current PGCA Configuration
12.
PGCA is now enabled and will continue to use the current PGCA configuration until
PGCA is disabled (tuned off) or the PGCA configuration is changed.
C.8.4 Save the Current PGCA Configuration
13.
Save the current PGCA configuration to either:
•
Flash memory using the CM Save command.
•
A user-defined configuration set, using the cm create and cm save_cfg commands..
Any parameter changes, including conditional access changes, that are made using a
remote unit are not automatically stored in flash memory. When the SE4000 configuration
is changed using a remote unit, an operational test should be performed to verify that the
system is operating correctly. Then the new configuration should be saved by issuing the
CM SAVE command.
If the SE4000 is reset, or looses power prior to issuing the CM SAVE command, any
changes made using the remote unit will not be restored. Instead, the SE4000 restores
the last changes saved to flash memory. Once the configuration is saved using the CM
SAVE command, the SE4000 automatically restores the saved settings when the unit is
reset or powered up.
