S1.4
S1.4 PCM Latency (Module 2 only)
OFF
PCM signal is delayed by 1 video frame (factory default)
ON PCM signal is minimally delayed
Same as S2.4 above, but for module 2.
S1.5
S1.5 Module 2 Pulldown Mode

S1.6 Module 2 Configuration Download
OFF
Standard operation (factory default)
ON Configuration download via RS232
If firmware download to decoder module 2 is required, plug the short flat
cable (W1) coming from the METADATA OUT front-panel socket to the
PCB socket P8 (labeled UPDATE2).
The pin assignment of the METADATA OUT socket (9pin D-type, female, UNC
4-40 thread) in this case is as follows:

Metadata and Downmixing: A Dolby
®
E stream contains metadata with vari-
ous information on the encoded signal. This information can be read out from
the front panel connector. The D21m Dolby
®
E decoder card only uses this
information in case a 2-channel stereo downmix is required from a 5.1-chan-
nel surround signal within the Dolby
®
E stream; then the decoder interprets
the center and surround channel levels and uses them for the internal down-
mixer that is activated by the DIP switches S1.7 and S1.8. The downmix can
be made constantly available and, subsequently, overwriting any audio data
that was contained on these channels beforehand (‘forced downmix’), or it is
possible to ‘fill’ the channels 7/8 or 15/16 only if the metadata indicate that
these channels are not being used otherwise (automatic downmix).
