  Button press/release emulation
Emulating a button press or release causes the commands and actions that are associated with the button via the main 
event script to be executed. Button emulation triggers only what has been set up via the Front Panel tab in Global 
Confi gurator. Emulation does not trigger the built-in SIS input switching commands (
X20)
 !) or the projector power 
on/off commands (1P or 0P).
See the diagrams below and on the next page to determine the number of the memory block associated with each 
button.
