4.1 DIP switch functions
The two sets of DIP switches are labeled with a number running from 1 to 15. The 16 th 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 Multicon
GYDA control, see description for DIP switch 16 below.

w/14:9 PB These 3 DIPs choose which
parts of the picture are
preserved or cropped away
when aspect ratio must be
performed.

DAC format
DIP[6 7] = [Off Off] => CVBS
DIP[6 7] = [Off On] => YPbPr
DIP[6 7] = [On Off] => SVideo
DIP[6 7] = [On On] => RGB These two DIPs choose video
DAC output format.
8 SD video
DAC
modulation Off: PAL B/G + NTSC
On: PAL N + PAL M Selection between PAL B/G and
NTSC or PAL M and PAL N is
automatic, based on video
input.
9 Black setup
disable Off: Black setup for NTSC
On: No black setup For NTSC only.
10 Input priority Off: Optical input has priority
On: Electrical input has priority
This switch has no effect for
boards without the optical input
(-R option).

select one of the de-embedded
groups.
