System Timing
The MAXX-2420-EX is equipped for use with an external genlock signal as a timing reference.
This causes all outputs to be synchronous with other video signals in a facility.
Adjustment of Genlock Timing will fine tune this synchronization to compensate for
differences in equipment and wiring. This global setting for all outputs allows timing to be varied
by one line of video. 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 that the picture will rise or fall 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 on different and possibly inappropriate lines.
Figure 27 - 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.
