Config Menu
To update the parameters press the Update Parameters button. When all
parameters are updated you can insert them either at the selected position
or at the end.
All actions (Insert, Update Parameter, and Remove) are applied to all com-
mands in the list as long as no command is selected. When you select one
or more commands, only the selected commands are affected. You can
select/de-select commands with the buttons in the top row (Deselect All,
Select All, etc.)
CAUTION This dialog offers a convenient way to insert multiple commands in a macro.
It should NOT be used to replace the Emem system. The switcher software is
optimized to handle recalls of snapshots and timeline in a very efficient way.
Macro commands are send from the panel and handled in the mainframe as
if they were send by the operator. For a large amount of commands execution
in the same frame cannot be guaranteed.

If the same result is achievable with a snapshot, this is the better choice. 
If the granularity of the Emem Define Memo is not fine enough to change
some parameters without touching others multiple macro commands offer a
solution.
