Monitoring Your Projectors
The EMP Monitor screen lets you monitor your projectors 
using the Status, Video Source, and Error icons shown below. 
This lets you see which projectors are currently being used, 
from which source (or port) they are projecting an image, and 
if a problem occurs.
Note: To monitor a projector when it’s in standby mode (plugged 
in but not projecting), you must first select 
Network ON as the 
Standby Mode setting in the projector’s Advanced1 menu. You 
can monitor up to 64 projectors.
For detailed status information, select the projector and click 
View details. 
The following tables explain the status, video source, and error 
icons. 
Controlling Your Projectors
The control buttons in the upper-right of the EMP Monitor 
screen let you turn the projectors on and off and select video 
sources. (Hold the mouse pointer over a button to see a 
description of its meaning.) Make sure you’ve selected the 
projector(s) you want to operate before clicking one of the 
buttons. 
Note: To turn on a projector when it’s in standby mode (plugged in 
but not projecting), you first select 
Network ON as the Standby 
Mode
 setting in the projector’s Advanced1 menu.
