Save, recall, and directly write global and room presets

N• If you try to recall a preset that is not saved, the matrix switcher responds with the error code E11.

•If you try to save a room preset for a room that has not been created, the switcher responds with the error code E11.

•The following characters are invalid in preset names: + - , ` @ = [ ] { } ‘ “ ; : \ and ?.

Save current configuration	X(,	SprX(]	Command character is a
as a global preset			comma.
Example:	9,	Spr9]	Save current ties as preset 9.
Recall a global preset	X(.	RprX(]	Command character is a
			period.
Example:	5.	Rpr05]	Recall preset 5, which
			becomes the current
			configuration.

NThe 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, each output position’s tied input (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.
