4.1 DIP switch functions
th
The two sets of DIP switches are labeled with a number running from 1 to 15. The 16 DIP is
labeled
OVR.
Note that the left DIP switch of the horizontal DIP package is number 1
.
The
top DIP switch of the vertical DIP package is number 9. Default settings as delivered from
factory should be all DIPs in the Off position. The module will then be under Gyda control,
see description for DIP switch 16 below.

SDI OUT 1
Off: processed mode
In through mode the
video goes through a
re-clocker only, and
the video DAC
output will also be
HD (always YPbPr).
+
On: through mode
Video DAC out
2
SDI OUT 2
Off: processed mode
In through mode the
video goes through a
re-clocker only.
On: through mode
These 2 DIPs
choose aspect ratio
for down-converted
video.
3 - 4
Aspect ratio
DIP[3 4] = [Off Off] => 16:9
DIP[3 4] = [Off On] => 4:3
DIP[3 4] = [On Off] => 16:9 LB
DIP[3 4] = [On On] => Previous
setting preserved
“Previous setting
preserved”: With
DIPs in this position
before the module is
booted into manual
mode; the module
will keep the
previous value set by
Gyda.
These two DIPs
choose video DAC
output format for SD
output. Analog HD is
always YPbPr.
5 - 6
SD video DAC
format
DIP[5 6] = [Off Off] => CVBS
DIP[5 6] = [Off On] => YPbPr
DIP[5 6] = [On Off] => SVideo
DIP[5 6] = [On On] => RGB
7
SD video DAC
modulation
Off: PAL B/G + NTSC
Selection between
PAL B/G and NTSC
or PAL M and PAL N
is automatic, based
on video input.
On: PAL N + PAL M
8 Black
setup
disable
Off: Black setup for NTSC
For NTSC only.
On: No black setup
9
Input priority
Off: Optical input has priority
This switch has no
effect for boards
without the optical
input (-R option).
On: Electrical input has priority
The 2 first of these 4
DIPS select one of
the de-embedded
groups. The next two
10 - 11
Audio DAC and
AES group
DIP[10 11] = [Off Off] => Gr1
DIP[10 11] = [Off On] => Gr2
DIP[10 11] = [On Off] => Gr3
DIP[10 11] = [On On] => Gr4
