Using the MGP and the matrix switcher after the MGP is synchronized to
the matrix switcher
After you have performed step 6, above, be sure to do the following when using the
MGP with the switcher:
•
Set up the inputs so that MGP window 1 always displays input 1, window 2
displays input 2, window 3 displays input 3, and window 4 displays input 4.
• Perform all input switching using the matrix switcher. A 1-second RGB
delay is recommended to minimize the amount of video sync noise while the
processor locks onto the new signal.
• Window presets can be recalled, but they must be recalled “without input,” so
that the inputs remain matched to the windows with the same numbers.
• Input presets do not have to be issued manually to the MGP. The MGP senses
when the matrix switcher changes input ties and recalls the matching input
preset.
Minimizing synchronization problems when not using the Sync to Matrix
feature
When operating the system using a manually configured control system (for which
Sync to Matrix was not used), you can avoid synchronization problems that cause
unwanted image blanking or scrambling during input switches by doing the
following:
1
. While setting up the switcher and the MGP to work together, set the RGB
delay on the matrix switcher to greater than or equal to 1.0 second.
2 . Create a tie on the matrix switcher from desired input X to the output number
that corresponds to MGP window Y, in which input X will be displayed.
3 . Immediately (within 1 second) recall the input preset with the same number
as switcher input X that you selected in step 2 (preset X), to MGP window Y.
N Input presets cannot be recalled via the MGP front panel. You can recall them
via SIS commands (see chapter 4, “Software Configuration and Control”), the
MGP 464 Web pages (see chapter 5, “HTML Configuration and Control”), or
the Windows-based control software/Preset Selector (see chapter 4, “Software
Configuration and Control,” and the control software’s help file).
