Rear Connector Panel 
 
The projector provides eight discreet video connectors:  
two component RCA, two S-video, one composite RCA, one M1-DA (HD, DVI, and computer),   
one VESA (HD, HD component, and computer) and one component D5. 
It also has a mini-jack input for a Knoll, Niles or Xantech-compatible IR repeater and an RS-232 connector 
for serial control. The Command Line Interface (CLI) specifications and commands are listed in the 
Appendix. 
Two 3.5 mm mini-
jack triggers 
provide 12-volt 
current. Trigger 1 
provides a con-
stant output while 
the projector is on. 
If you connect your 
projection screen 
to Trigger 1, when 
you turn on the 
projector the 
screen will move 
down; when you 
turn the projector 
off, the screen will 
return to the 
storage position. 
Trigger 2 provides 
a 4:3 aspect 
trigger. When you 
select 4:3 in the 
Aspect Ratio menu 
or from the Resize 
button on the 
remote, a 12v 
signal will be sent 
after a five second 
delay. Use this 
trigger for screens 
with 4:3 aspect 
curtains. When 
you switch back to 
16:9 format, the 
curtains open to 
reveal the entire screen.
