Save, recall, and directly write presets
NOTES: • If you try to recall a preset that is not saved, the matrix switcher responds with the error code E11.
• The following characters are invalid or not recommended or not recommended in preset names: + - , ` @ = [ ] { } ‘ “ ; : | \ and ?.

Recall preset 5, which becomes the current
configuration.
Direct write process —
NOTE: The direct write of a global preset should always be preceded by a clear global preset ties command of that same preset number,
as shown below. In a directly-written preset, the tied input of each output position (or no tied input) remains unchanged unless
overwritten or cleared.
If you do not clear the ties in a global preset number before you directly write a global preset to that number, ties that are part of
the previous version of the specified preset with the same number can unexpectedly become part of the newly-created preset.
