Connecting the Mouse and Serial Cables
If you want to use the remote control as a mouse or use the ELP 
Link III software, you need to connect the main cable. It provides 
connectors for:l
The Mac mouse cable (to use the remote control as a mouse)
l
The Mac serial cable (to use the ELP Link III software and the 
Effects buttons on the remote control)
Refer to this illustration while following the steps below.

Connecting the Audio Cable
1. If you will be using audio, connect one end of the audio cable to 
the Audio 1 jack on the projector. (Use the Audio 2 jack if you 
are connecting a second computer.) 
2. Connect the other end of the audio cable to the audio-out port on 
your PowerBook. 
Note: After you turn on the projector and computer, you’ll need to choose 
Mirroring in the Display Control Panel if you set up your configuration to 
display on the LCD screen as well as the projector screen.

Connecting to a High-End Workstation
The PowerLite 7200 and 7300 are capable of remapping input 
resolutions up to 1280
´1024 pixels. Since 1280
´1024 pixels is the 
default resolution for most leading workstations, this capability makes 
these projectors the best portable solution for the display of 
workstation video output.
There is no standard for workstation video output. Those workstations 
that follow the SXGA standard and use the HD15 connector don’t 
need an adapter cable. The most popular workstations use a 13-pin 
13W3 connector, which requires an adapter cable (ELPKC06).
In addition, workstations pass the sync (synchronization) signal 
differently, so the ELPKC06 adapter cable has a DIP switch to control 
sync routing. Contact your audio/video dealer for information on 
connecting your workstation.
Connecting to a Video Source
You can connect a VCR, a camcorder, a laser disc player, DVD player, 
or any other compatible video image source to your projector.
The projector can receive composite video, S-Video, or component 
video. Your equipment has composite video if your video source has a 
one-pin RCA video jack. Your equipment has S-Video if your video 
source has a four-pin (mini-DIN) video jack. Your equipment has 
component video if your video source has a three-connector (Y, R-Y, 
B-Y) video jack.
Note: The projector is not compatible with a cable TV-style F connector.

You can connect the projector to an S-Video source, a composite video 
source, and a component video source at the same time. However, the 
projector automatically selects the S-Video as the video source. To 
display composite or component video, first disconnect the S-Video 
source.
The projector supports NTSC, PAL, and SECAM video formats, and 
automatically detects and identifies the video format. However, you 
can specify that a single broadcast format be detected. (See Chapter 3.) 
Note that the projector will then be able to detect only one type of 
video signal.
The type of cable you use to connect the video source to the projector 
depends on whether you have composite video, S-Video, or 
component video. For composite video, use the audio/video (A/V) 
cable supplied with the projector. For S-Video, use the S-Video cable 
supplied with your video device or obtain one from your computer or 
video equipment dealer. For component video, use the BNC type 
cable that came with your video source. The illustration below shows 
the S-Video, component, and composite connectors.4 2

To connect a video source to the projector:
1. Turn off the projector and video source if they are on.
2. If your video source uses a small, round, one-prong composite 
(RCA) video connector, you’ll need the audio/video cable that 
comes with the projector. If your video source uses a large, round, 
four-prong S-Video connector or a BNC type connector, you will 
need to purchase the appropriate cable or use the cable that came 
with your video source.
3. For composite video, connect the yellow RCA plug on one end of 
the audio/video cable to the projector’s Video jack. Connect the 
other yellow RCA plug to the video-out jack of your video source.

4. Connect the other plugs on the audio/video cable to the Audio 
jacks of the projector: insert the white plug into the L jack and the 
red plug into the R jack. Connect the plug at the other end of the 
audio/video cable to the audio output jacks of the video source. 
5. For S-Video, insert one end of an S-Video cable into the 
projector’s S-Video connector. Insert the other end into the 
S-video-out jack of your video source.
6. For component, insert three ends of a BNC cable into the 
projector’s R/R-Y, G/Y and B/B-Y jacks. Insert the opposite ends 
of the cable into the Y/Video, C/R-Y, and B-Y jacks on your 
component video source. (Don’t insert any of the cable ends into 
the HD/Sync and VD jacks.)
7. Make sure the Computer 2/BNC switch is set to BNC.
Note: When the Computer 2/BNC switch is set to BNC, the projector 
is unable to project the Computer 2 image signal.
Note: Use a standard BNC cable, which you can purchase from any 
computer store. The 5BNC video cable supplied by EPSON as an 
optional accessory does not work with component video.
