Dip-switch settings - video interface
Some settings must be selected by the dip-switches on the
video interface. Dip position down is ON and position up is OFF.
See following chapters for detailed information.
1.4.1.
Enabling the interface’s video inputs (dip
2-3)
Only the enabled video inputs can be accessed when switching through the interface’s video
sources. It is recommended to enable only the required inputs for the disabled will be
skipped when switching through the video interfaces inputs.
1.4.2.
Rear-view camera setting (dip 5)
If set to OFF, the interface switches to factory LVDS picture while the reverse gear is engaged
to display factory rear-view camera or factory optical park system picture.
If set to ON, the interface witches to its rear-view camera input CAM while the reverse gear
is engaged.
1.4.3.
Monitor selection (dip 7-8)
Dips 7 and 8 customize the monitor-specific video settings which sometimes even vary
within head units of the same version, caused by different monitor specifications. It is
necessary to try all possible combinations of the 3 dips while a working video source is
connected to the chosen input of the interface. One of the combinations will show the best
picture size and quality (some may give no picture). It is possible to first hot plug through the
dip combinations. If there is no visible change of picture after trying all options, retry and
disconnect the 6pin plug of the video interface between every change of the dip setting.
Dip 1, 4 and 6 are out of function and have to be set to OFF.
After each Dip-switch-change a power-reset of the Video Interface has to be performed!
