I/O presets
Overview
The ISM 824 has a total of sixteen I/O preset memory addresses available. Each
preset can be saved and recalled using the front panel input and output buttons
with presets 1 through 8 assigned to the input buttons, and presets 9 through 16
assigned to the output buttons. Any current tie configuration can be saved to any
one of the preset locations, in any order. Saving the current configuration to an
existing preset overwrites that existing preset in favor of the new configuration.
Likewise, when a preset is recalled, it replaces the current (active) configuration,
which is then lost unless already saved in a previous preset location. The recalled
preset overwrites all of the current configuration ties, in favor of the recalled
configuration. Read all the notes below.
N I/O presets are not the same as memory or user presets, which are used to store
image sizing and centering configurations.
N Presets can not be viewed from the front panel, unless recalled as the current
configuration.
N Only the audio and video ties are stored and recalled as a preset. Audio gain
settings are not saved, and do not change when a preset is recalled.
N The current configuration and all I/O presets are stored in non-volatile memory.
When power is removed and restored, the current configuration is active and all
presets are retained.
N When a preset mode is recalled, all the input and output buttons with previously
assigned presets light red.
