MVX VGA A Matrix Switchers • Operation
PRELIMINARY
Using global presets
The current configuration (configuration 0) can be saved as a preset in any one of
32 preset memory addresses. Preset locations are assigned to the input buttons
and output buttons. On the MVX 128 A, up to 20 presets can be selected from the
front panel to be either saved or retrieved. On all other models, all 32 presets are
available from the front panel. When a preset is retrieved from memory, it becomes
the current configuration.
N
• Only the audio and video ties are stored and recalled; audio gain settings are
not saved, and they do not change when a preset is recalled.
• Presets cannot be viewed from the front panel unless recalled as the current
configuration. Presets can be viewed using Extron’s Windows-based control
program. See chapter 5, “Matrix Software”, for more details.
• The current configuration and all presets are stored in non-volatile memory.
When power is removed and restored, the current configuration is still active
and all presets are retained.
• When a preset is recalled, it replaces the current configuration, which is lost
unless it is also stored as a preset. The recalled preset overwrites all of the
current configuration ties in favor of the preset configuration ties.
• Preset numbers greater than 20 (that are too high to be available from the
front panel) are accessible via serial port control.
• Figure 3-32 shows the presets associated with the various input and output
buttons for the MVX 128 VGA A. Figure 3-33 shows the presets associated
with the various input and output buttons for the MVX 1212 VGA A,
MVX 168 VGA A, and MVX 1616 VGA A.
