IN1804 Seamless Scaling Switchers • Operation 42
Input Presets
The IN1804 Series switchers have 128 memory slots in which you can save input presets.
These presets allow a matrix switcher with multiple types of video inputs (such as an XTP) to
be placed upstream from the IN1804 to expand the number of video sources.
Input presets can be saved and recalled through SIS commands (see the Presets
commands on page 70) and through PCS (see the IN1804 Series PCS Help File).
• When you recall an input preset, it fills the output raster based on the sizing and
positioning that it had at the time it was saved. For example, a video source that was
configured to be zoomed when it was previously saved as a preset is still zoomed, even
if recalled to a smaller output raster.
• Input presets can be saved based on one input rate and recalled to a different rate. This
enables presets to be used as aspect ratio or other quick-sizing shortcuts. Because the
size and position is saved as a percent of the raster, the preset can be recalled to any
scaled output and the saved size and position are scaled proportionally on the output.
Values for the following settings are saved in input presets:
• Preset name • Detail
• Audio gain and attenuation • Horizontal image position
• Film mode detection • Vertical image position
• Contrast • Horizontal image size (width)
• Brightness • Vertical image size (height)
Saving a preset when using a matrix switcher
When using the IN1804 with a matrix switcher, do the following to save a preset:
1. Switch each input of the matrix to the IN1804.
2. Configure each input: size, position, detail, brightness, and contrast.
3. Save the settings to a preset for recall by the control system when that matrix input is
routed to any IN1804 input.
Reset Modes
The IN1804 series switchers have three reset modes (numbered 1, 4, and
5). Use a small screwdriver or stylus to press and hold the recessed
Reset button on the rear panel (see
2
in the image at right) to advance
through the modes. The Reset LED (
1
) blinks to indicate each mode
that is enabled (see the Reset Mode Summary table on the next page
for a description of the reset modes and how to select them).
You can also perform resets using the OSD (see Factory Reset on
the Advanced submenu on page 40), SIS commands (see the Resets commands on
page 77), and PCS (see the IN1804 Series PCS Help file).
ATTENTION:
• Review the reset modes carefully. Using the wrong reset mode may result in
unintended loss of flash memory programming, port reassignment, or processor
reboot.
• Étudier de près les différents modes de réinitialisation. Appliquer le mauvais mode
de réinitialisation peut causer une perte inattendue de la programmation de la
mémoire flash, une reconfiguration des ports ou une réinitialisation du processeur.
