5.3 DMUX DIP switches
Switch # Function name Function DIPs Comment
1 - 3 Shuffler Stream to output allocation:
1 2 3 O1 O2 O3 O4
[OFF][OFF][OFF]: 1 2 3 4
[ON ][OFF][OFF]: 1 1 3 4
[OFF][ON ][OFF]: 1 1 3 3
[ON ][ON ][OFF]: 1 1 1 4
[ ---- ][ ---- ][ON ]: 1 1 1 1
( ----
means “Don’t care”. As long as
RD2=ON, any combination of
values for RD0 and RD1 will give
the same result.)
Changing the
shuffler DIPs to
something other than
[OFF][OFF][OFF] will
substitute one or
more of the inputs 2-
4 for a duplicate of
input 1 or 3. This
means that the card
can be used as a
distribution amplifier.
4 - 5 Input selector
4 5 INPUT
[OFF][OFF]: Optical (manually)
[ON ][OFF]: Electrical (manually)
[OFF][ON ]: Auto (pri. optical)
[ON ][ON ]: Auto (latching) For boards without
the optional optical
input, electrical input
will always be
selected and these
DIPs have no
function.
6 - 7 Video fallback 6 7 Output video
[OFF][OFF]: Black, auto vstd.
[ON][OFF ]: Color bar, auto vstd.
[OFF ][ON]: No fallback
[ON ][ON ]: No fallback
(auto vstd. = automatic standard
detection - 525/625 lines according
to the lost SD-SDI signal) There is no on-board
DVB-ASI signal
generator available.
When losing a DVB-
ASI signal, no
fallback is available.
The output will
simply be lost,
regardless of the
fallback setting.
8 OVR Off: Multicon GYDA mode
On: Manual mode This DIP is only read
at power up.
OVR is short term for
Multicon GYDA
override.
