If multiple services are selected for decryption and Decrypt Components Follows
Decode is selected then changing the decode service will cause all decrypted
services to temporarily stop descrambling.

Status
3.11.2.8.1
CAM Status
The RX8000 does not have the ability to report detailed status of the CAM because
of the CAM's "black box" nature. The unit is capable of displaying if it has been
successful in configuring the services and sending the configuration information to
the CAM.
The following statuses are available from the CAM:
•
•
EN/LZT 790 0005 R7A
PID filter that strips out unused PIDs. Depending on the content of the transport
stream and the services selected, this feature will reduce the incoming bit rate to
below the 72 Mbps threshold. This is available on the RX8200 only.
Select Service Limiting Bit Rate – This defines the bit rate threshold of the
incoming transport stream for activating Service Limiting. Service Limiting must
be enabled for this to take effect. This is available on the RX8200 only.
CAM Voltage Forced 3v3 – This overrides the 3V3 / 5V sense for the CAM.
Some CAMs may be incapable of working correctly with 5 V despite being
advertised as supporting 5 V. This control forces the unit to supply only 3.3 V to
the CAM. The IRD must be reset for this to take effect. This is available on the
RX8200 only.
CAM Enable Burst Mode – Where the CAM is inserted in to the IRD and no
transport stream is detected or no services are listed, try enabling this mode
which will attempt to fix the stream going in to the CAM. This is available on the
RX8200 only.
CAM Compatibility Mode (max TS rate is reduced) – This is available on the
RX83xx IRD range only. Where the CAM is inserted in to the IRD and no
transport stream is detected or no services are listed, try enabling this mode
which will attempt to fix the stream going in to the CAM. This is similar to
enabling Burst Mode in the RX8200.
72 Mbps with the CAM inserted since it does not support the Service
Limiting feature available on the RX8200. It should be noted that enabling
CAM Compatibility Mode reduces this maximum bit rate for the transport
stream.
Attempting Decryption – This status means that the RX8000 has been
successfully configured and that all configuration information has been sent to
the CAM. This does not mean that the CAM is decrypting.
Decryption Error – This means that the RX8000 has not been able to
successfully setup or that the PIDs selected for descrambling still have their
descramble bits set within the Transport Stream header.
