computer connected to Analog 1. Then later, using
the same input connector but a different computer
you set up the Margay for a 1600x1200 @ 60Hz. You
re-adjust the Black and White Levels, because they
are different.
Still later you plug in the first computer with its
1024x768 @ 65Hz picture. Immediately, the Margay
recognizes that it has seen this signal type before, and
it recalls the Black and White Levels from its internal
memory.
It does not Do Frequency or Phase or anything
else, because it recognizes that this input was used
before, and the previous settings are probably correct.
Possible issue with Mode specific memory
Suppose that after setting up the 1024x768 and
1600x1200 pictures, you connect a third computer
that is 1024x768, but it has a different requirement
for Black and White Level. In this case, the Margay
would use the
wrong values for these levels.
To prevent this from happening, use the memory
slots as described below.
Switching input connectors
Now suppose you use Analog 2 to bring in a pic-
ture that uses the component YPbPr video. You
change the Colorspace setting to YPbPr. If you switch
back to Analog 1 in the Picture menu, the Margay
switches back to the RGB Colorspace, because Color-
space is specific to the input connector.
Possible issue with Input specific memory
What happens if you switch back to Analog 1 and
the picture there is YPbPr? The Margay has no way to
know this, no way to detect the difference between
RGB and YPbPr, so it will use the wrong Colorspace.
To prevent this from happening, use the memory
slots as described below.
Global parameters
In none of the examples above does the Margay try
to change the Baud Rate or the Color Balance values,
because these items are saved globally.
Memory slots
The Margay has memory slots, 40 of them. Each
slot memorizes all the mode specific and all the input
specific parameters as well as the input connector
used.
When you recall a memory slot, you recall exactly
the way the Margay was set up when the memory
was saved.
• The change is immediate. There is no waiting for
the Margay to Do Frequency or Do Phase or any
of that.
• The switch includes the correct input connector.
• The memory slots can be named something spe-
cific to your application: “C OMPUTER XL-61 ,”
“ MAIN DVD PROGRAM .”
• And there are 40 of them, not just 10.
