You can connect the projector to three computer sources or 
four video sources—up to a total of four sources. You can 
include an independent sound channel for each source. (See 
the User’s Guide for complete setup instructions.) Using 
EasyMP,

®

 you can also connect over a wireless network, or 

view images on a memory card or digital camera.

The following connections are possible, depending on the 
signal your equipment generates and its available output ports.

Note that the projector’s 

Computer

 and 

BNC

 ports accept a 

variety of input signals. If you’re connecting to one of these 
ports, you’ll need to make sure that the correct input signal 
setting is selected, or your image won’t display properly. 

To change the input signal setting, do the following:

1. After turning on the projector, press the 

Menu

 button. The 

menu screen appears.

2. Select the 

Setting

 menu.

3. Change the 

Computer

 

Input

 or 

BNC

 

Input

 setting as 

needed to match the signal generated by your computer or 
video equipment. (See the User’s Guide for more 
information.)

You can play sound through the projector’s speaker system or 
you can attach an external speaker system.

To play sound through the projector, use one of the following 
cables that came with your projector: 
❏ If you have a computer or video equipment connected to 

the 

Computer

 or 

DVI

 port, use the stereo mini-jack cable. 

Connect one end to the correct audio port (see below), and 
the other end to the audio-output connector on your 
equipment.

❏ If you have a computer or video equipment connected to 

the 

BNC

 ports, or to the 

Video

 or 

S-Video

 port, use the 

the RCA-style audio cable. Connect one end to the jack 
corresponding to the connected port, and the other end to 
the audio-output connector on your equipment.

To connect external speakers, use the 

Audio Out

 port on the 

back of the projector. You may be able to use a commercially 
available audio cable with a stereo mini-jack connector on one 
end and pin jacks on the other, or you may have to purchase a 
special cable or use an adapter, depending on your stereo 
system. See the User’s Guide for more information.

If you’ve connected a computer to the projector, you can 
use the projector’s remote control as a wireless mouse by 
connecting the USB cable that came with the projector to 
the projector’s 

Type B

 USB port. The wireless mouse function 

is supported on systems with a USB port running Windows

®

 

XP, 98, 2000, or Me, or Macintosh OS 8.6 to OS X 10.2. See 
the User’s Guide for more information.
