Using the MGP Pro and the matrix MGP Pro after the MGP Pro is
synchronized to the matrix switcher
After you have performed step 6 on the previous page, be sure to do the following when
using the switcher with the MGP Pro:
• Set up the inputs so that MGP Pro 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 Pro. The MGP Pro senses
when the matrix switcher changes input ties and recalls the matching 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 matrix switcher and the MGP Pro to work together, set the RGB
delay on the 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 Pro 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 Pro window Y.
NOTE: Input presets cannot be recalled via the MGP Pro front panel. You can recall
them using SIS commands (see the Remote Configuration and Control section
beginning on page 42) or the for the Preset Selector software program, which is
installed with the MGP Series Control Program (see the MGP Series help file).
Application 2: Connecting Multiple MGP Pros in Succession
(Daisy-chaining)
By connecting multiple MGP Pros together in succession (“daisy-chaining”) via the HDMI
Output and HDMI Background connectors, you can display up to 12 windows on the output
screen. You can connect up to three MGPs in this way (see the examples on the next two
pages).
NOTE: This application can also be used with an MGP 462 Pro. However, because
the MGP 462 Pro has only two windows, you are able to display half the number of
windows that the MGP 464 Pro can support. For example, when you daisy-chain three
MGP 462 Pro processors together, 6 windows are provided instead of 12.
Connecting via the HDMI Background connector has the advantage of the input not being
scaled. Therefore, no analog or digital sampling is required and there is no signal loss.
NOTE: In figures 42 , 43 , and 44 on the next two pages, the MGPs are given letters in
the order of their priority, starting with A being the unit closest to the output display.
Therefore, the first MGP Pro in the chain is shown as unit C (or B, if there are only two
MGPs). The second MGP Pro is designated as unit B, and the third is unit A.
