source to the output sources with no modification.  Pass-Thru is available in
all modes except when the input source is AES/EBU -- because an AES/EBU
input carries no SCMS data, there is nothing to pass through when
AES/EBU is selected as the input source. 

SCMS "None" Mode

When SCMS mode is set to None, the outgoing SCMS bits are set to indicate
that there is no copy protection asserted (the material may be copied).  If the
source is coaxial or optical S/PDIF, then the CO3 actually strips the SCMS
material out of the incoming stream and replaces it with bits that indicate no
copy protection.  Also, in this case the "None" LED will blink to indicate that
the AES/EBU output is not valid.

If the source is AES/EBU, there is no incoming SCMS data.  Therefore this
SCMS mode will add the "no copy protection" information to the outgoing
S/PDIF streams for you.

SCMS "Original" Mode

When SCMS mode is set to Original, the outgoing SCMS bits are set to
indicate that the source material is the original master and not a copy.
Therefore most receiving units will accept this material.  Similar to "None"
mode, if the source is coaxial or optical S/PDIF, then the CO3 actually strips
the SCMS material out of the incoming stream and replaces it with bits that
indicate original material.  Also, in this case the "Original" LED will blink to
indicate that the AES/EBU output is not valid.

If the source is AES/EBU, there is no incoming SCMS data.  Therefore this
SCMS mode will add the "original" information to the outgoing S/PDIF
streams for you.

SCMS "1st Generation" Mode

When SCMS mode is set to 1st Generation, the outgoing SCMS bits are set to
indicate that the source material is a copy.   Therefore receiving units that
include SCMS will not accept this material -- this can be useful for protecting
the copyright of commercial material.  Similar to "None" and "Original"
modes, if the source is coaxial or optical S/PDIF, then the CO3 actually strips
the SCMS material out of the incoming stream and replaces it with bits that
indicate 1st generation material.  Also, in this case the "1st Generation" LED
will blink to indicate that the AES/EBU output is not valid.

If the source is AES/EBU, there is no incoming SCMS data.  Therefore this
SCMS mode will add the "1st Generation" information to the outgoing
