FOR-A FA-9520 Operation Manual page 210

If CEA608 or S334-1 CC closed caption data is detected in the input signal, and
the FS1 and/or FS2 converter output signal format(s) is/are 1080/59i or
720/59p, the detected closed caption data will be automatically converted to
CEA708. However, if CEA708 closed caption insertion is disabled, the data will
not be inserted.
If FS1 and/or FS2 converter output format(s) is/are 1080/PsF or 1080/59p, the
CEA708 closed caption data insertion will be automatically terminated.

Meanwhile, if CEA708 closed caption data is detected in the 1080/59i or
720/59p HD-SDI input signal, and the FS1 and/or FS2 converter output signal
format(s) is/are 525/60, the detected closed caption data will be automatically
converted to S334-1 CC and/or CEA608 CC.
However, if S334-1 CC and/or CEA608 closed caption insertions are disabled,
the data will not be inserted. If the input signal is 1080/59p or 1080/PsF,
detection and automatic conversion to S334-1 CC and/or CEA608 CC will not
be performed.
Closed caption data output to SD-SDI ancillary data will stop when data input is lost. If
closed caption data input is lost, the ancillary data output will be conducted according
to the ANC LOSS SET settings. See section 5-9-7 "ANC LOSS SET" for details.
Ancillary data combinations that cannot be simultaneously embedded to the same
line.

If the same line is set for the ancillary data combination described as "Unable to set to same line",
and both ancillary data types are set to be embedded under ANC Data Embed, an error
message "Identical ANC line location settings!" will appear. If the sign is displayed, ancillary data
will not be properly embedded. The line settings must be properly set. Usually the default value
will properly embed the ancillary data. Keep this in mind when changing the value to configure a
system with other devices.
