5.2 MUX DIP switches
Switch # Function name Function DIPs Comment
1 - 3 Shuffler Input to stream allocation:
RD0 RD1 RD2 S1 S2 S3 S4
[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. Usually
this should rather be
done on the DMUX
side.
4 - 6 Cable equalizer
bypass EQ0 EQ1 EQ2
[OFF][OFF][OFF]: Bypassed: none
[ON ][OFF][OFF]: Bypassed: 1
[OFF][ON ][OFF]: Bypassed: 1+2
[ON ][ON ][OFF]: Bypassed: 1+2+3
[ ---- ][ ---- ][ON ]: Bypassed: all
( ----
means “Don’t care”. As long as
EQ2=ON, any combination of
values for EQ0 and EQ1 will give
the same result.)
Changing the cable
equalizer DIPs to
something other than
[OFF][OFF][OFF] will
bypass one or more
of the cable
equalizers. This will
normally result in
reduced
performance. Only
use this feature if
you understand why
you would want to do
it.
