System Timing
The MAXX-1200 is equipped for use with an external genlock signal as a timing reference. This
causes all outputs to be synchronous with other video in a system. Select the use of genlock
reference by clicking the Video Sync External radio button.
When External is selected, adjustment of Genlock Timing will fine tune this synchronization to
compensate for differences in equipment and wiring. This is a global setting that allows the output
timing to be varied for all outputs. The Vertical (lines) setting rarely needs to be adjusted. If required,
it would be adjusted so that the output of the first line of video happens concurrently with other
contributing inputs. The visible effect is a rise or fall of the picture by one line, when viewed at the
output of a timed video switcher or on a genlocked monitor. Note that this setting can cause VANC
data to appear to downstream equipment on different and possibly inappropriate lines.
Figure 23 - Video Timing Adjustment
The Horizontal (nsec) adjustment is used to set the precise timing of the start of the frame relative
to the reference signal, in order to match with other contributing signals. The effect is not
normally visible; extreme settings may result in a slight visible shift of the picture from left to
right.
