Figure 15: The figure shows the component layout of the bottom side of the board. The slide
switches are highlighted with a red color.
3.2.11 Tri-level standard
This selects the video standard for the Tri-
level sync output. Note that there’s a separate
selector between Tri-level output and Black burst outputs, see ch 3.2.9.

3.2.12 Black-burst standard
This selects the video modulation for the Black burst sync outputs. The user must select the
modulation for 50 Hz input and 60 Hz input separately, and the module will use either based
on the detected frequency base of the input. The Black setup setting will only take effect for
NTSC output. Note that there’s a separate selector between Tri-level output and Black burst
outputs, see ch 3.2.9.

3.2.13 Signal integrity
This is where the user can select which types of input errors will result in an increase the
error counter, and which types of errors will simply be ignored. An excessive amount of errors
(that are not being ignored) will trigger an alarm.
