the connection ports or the type of cable being used.
 Use the optional VGA-HD15/BNC PC cable to connect the monitor port 
of the computer to the [Computer] port at the rear of the projector.
See Appendices: Optional Accessories   p.135
 Use a commercially-available 5BNC monitor cable (5BNC
/male-male) 
to connect the monitor ports of the computer to the [BNC] port at the rear 
of the projector.

Connecting to a ComputerUsing the Remote Control to Operate the Mouse Pointer (Wireless Mouse Function)
You can use the remote control as a wireless mouse to control the mouse 
pointer on the screen by using the accessory USB
 cable to connect the 
USB port of the computer to the [USB] port at the rear of the projector.
* When using the remote control as a wireless mouse, the [Page  ] and 
[Page  ] buttons on the remote control can be used to scroll back and 
forth through slides when projecting a PowerPoint presentation.

TIP
 The USB cable can only be connected to computers with a standard 
USB interface. If using a computer which is running Windows, the 
computer must have had a full version of Windows 98/2000/Me/XP 
Home Edition/XP Professional installed. If the computer is running 
a version of Windows 98/2000/Me/XP Home Edition/XP 
Professional that has been upgraded from an earlier version of 
Windows, correct operation cannot be guaranteed. 
 It may not be possible to use the wireless mouse function under some 
versions of both the Windows and Macintosh operating systems.
 Some computer settings may have to be changed in order for the 
mouse function to be used. Consult the documentation for the 
computer for further details.

Connecting to a ComputerConnecting an External Monitor
When analogue RGB signals from a computer are being projected, you can 
connect an external monitor to the projector in order to view the images on 
the external monitor at times such as when giving presentations.
Connect the external monitor using the cable that is provided with the 
monitor.

TIP
 Digital RGB images from a computer and video images cannot be 
output to an external monitor.
 The setting gauge for keystone correction and the configuration 
menus and help menus are not output to the external monitor.

Connecting to a Video Source
Projecting Composite Video
 Images
Use the accessory RCA video cable to make the connections.
CAUTION
When connecting the projector to other video sources, take the 
following precautions.
 Turn the power off for both the projector and the video source before 
connecting them. If the power for either device is on at the time of 
connection, damage may result.
 Check the shapes of the cable connectors and the device ports before 
making the connections. If you try to force a connector to fit a device 
port with a different shape or number of terminals, damage to the 
connector or port may result.
 Do not bind the power cable and the connecting cable together. If the 
power cable and the connecting cable are bound together, image 
interference or errors in operation may result.

Connecting to a Video SourceProjecting RGB Video Images
RGB video is used when projecting RGB signals from a video source other 
than a computer that is connected to the projector. Either of the following 
two connection methods can be used. Use whichever method is suitable for 
the video equipments port.Use the accessory computer cable to make the connections.
TIP
 After projection starts, change the BNC Input setting in the 
Setting menu to either YCbCr
 or YPbPr
 to match the 
signals from the video equipment.   p.83
