Connecting the Mouse Cable
To use the remote control as a mouse follow the steps below. If the 
Macintosh has a USB port, you can use the USB mouse cable 
included with the projector. If it has a round mouse port, you’ll need a 
Macintosh mouse cable; see your projector dealer for help in obtaining 
the correct cable.
1. Connect the round end of the USB mouse cable (or a Macintosh 
mouse cable) to the projector’s 
Mouse 1 port. 
  
2. Disconnect your Macintosh’s mouse cable. Connect the other end 
of the projector’s mouse cable to the mouse or USB port on your 
Macintosh.

Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speakers, you’ll need to connect the audio cable.
1. Connect one end of the audio cable to the 
Audio (Computer1) 
port on the projector. 
  
2. Connect the other end of the audio cable to the speaker or 
audio-out port on the Macintosh.

Connecting to a Second Computer 
If you want to connect a second computer to the projector, you need 
to use the BNC connectors (labelled 
Computer 2/Component 
Video
) on the projector. You’ll need a VGA (D-sub 15-pin) to BNC 
cable, which you can purchase from your computer or electronics 
dealer.
Because these connectors are also used for component video, you can’t 
use a second computer and a component video source at the same 
time.
Follow these steps to connect a computer to the 
Computer 2/
Component Video
 interface using a BNC cable:
1. Connect the VGA (D-sub 15-pin) end of the cable to the 
computer’s video port.
2. Connect the five connectors at the other end of the cable to the 
projector’s 
R/Cr/Pr (red), G/Y (green), B/Cb/Pb (blue), H/CSync 
(horizontal sync), and 
VSync (vertical sync) ports, as shown 
below.
3. To display images properly, make sure the BNC option in the 
projector’s Setting menu is set to 
RGB. See page 52 for 
instructions.
4. If you want to hear computer-audio through the projector, you’ll 
need an RCA-to-3.5 mm stereo cable (available for purchase from 
your electronics store or video dealer). 
Insert the cable’s 3.5-mm plug into your computer’s audio-out 
port. Then attach the RCA connectors at the other end of the 
cable to the 
S-Video/BNC ports on the projector.

							88Appendix A: Connecting to Additional Equipment5. If you want to use the remote control as a wireless mouse for the 
second computer, you need to use either the PS/2 mouse cable or 
the USB mouse cable that came with the projector.
Connect the round end of the appropriate mouse cable to the 
Mouse 2 port on the projector. Then connect the other end of 
the cable to the computer’s mouse or USB port.
Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions 
up to 1600
×1200 pixels. Since 1280×1024 pixels is the default 
resolution for most leading workstations, your projector is ideal for 
displaying workstation video output.
There is no standard for workstation video output. Workstations that 
follow the SXGA standard and use the HD15 (standard VGA) 
connector won’t need an adapter cable or any special connection 
device. However, your system may vary; contact your computer dealer 
if you need help connecting your workstation.

							Appendix A: Connecting to Additional Equipment89
Connecting to a DVI Video Source 
The projector’s Digital Visual Interface (DVI) receives pictures 
directly from your computer in digital format. This lets the projector 
display images of greater clarity than can be achieved using a standard 
analog VGA connection. 
To project images in digital video format, follow these steps:
1. Connect the computer’s DVI cable to the projector’s DVI port.
2. Using the tip of a pen or a small screwdriver, slide the 
Computer 1 interface switch to the right. (If you need to use the 
projector’s analog port again, be sure to slide the switch back to 
the left.)
If you want to connect audio for this computer, use the projector’s 
Audio (Computer 1) port; if you want to connect a mouse cable (to 
use the remote control as a wireless mouse), use the 
Mouse 1 port. 
note
You won’t be able to view 
images on a separate monitor 
when the DVI port is in use.

This appendix includes safety instructions and other important 
information about your EPSON PowerLite 7700p.
Important Safety Instructions
Follow these safety instructions when setting up and using the 
projector:

Do not place the projector on an unstable cart, stand, or table.

Do not use the projector near water or sources of heat.

Use attachments only as recommended.

Use the type of power source indicated on the projector. If you are 
not sure of the power available, consult your dealer or power 
company.

Place the projector near a wall outlet where the plug can be easily 
unplugged. 
Placez le projecteur près d’une prise de contacte où la fiche peut être 
débranchée facilement.

Insert the projector’s three-wire grounding-type plug into a 
properly grounded outlet. If you have a two-prong outlet, contact 
an electrician to replace it. Do not hold the plug with wet hands.

Take the following precautions for the plug. Failure to comply 
with these precautions could result in sparks or fire: Do not insert 
the plug into an outlet with dust present. Insert the plug firmly 
into the outlet.

Do not overload wall outlets, extension cords, or integral 
convenience receptacles. This can cause fire or electric shock.

							92Appendix B: Notices

Do not place the projector where the cord can be walked on. This 
may result in fraying or damage to the plug.

Unplug the projector from the wall outlet before cleaning. Use a 
damp cloth for cleaning. Do not use liquid or aerosol cleaners.

Do not block the slots and openings in the projector case. They 
provide ventilation and prevent the projector from overheating. 
Do not operate the projector on a sofa, rug, or other soft surface, 
or in a closed-in cabinet unless proper ventilation is provided.

Never push objects of any kind through cabinet slots. Never spill 
liquid of any kind into the projector.

Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself. Refer all servicing to 
qualified service personnel. Opening or removing covers may 
expose you to dangerous voltages and other hazards.

Unplug the projector during lightning storms or when it will not 
be used for extended periods. 

Do not place the projector and remote control on top of 
heat-producing equipment or in a hot location.

Unplug the projector from the wall outlet and refer servicing to 
qualified service personnel under the following conditions: When 
the power cord or plug is damaged or frayed. If liquid has been 
spilled into the projector, or if it has been exposed to rain or 
water. If it does not operate normally when you follow the 
operating instructions, or if it exhibits a distinct change in 
performance, indicating a need for service. If it has been dropped 
or the housing has been damaged.

If you use the projector in a country other than where you 
purchased it, use the correct power cord for that country.

Remote Control Information
You can operate the projector by remote control via a line-of-sight 
infrared (IR) receiver at the front and rear of the projector. The 
projector may not respond to remote control commands under the 
following conditions:

There is an object between the remote control IR emitter and the 
IR receiver on the projector.

Ambient light is too bright.

Certain types of fluorescent lighting are used.

A strong light source shines into the IR receiver.

Other equipment that emits infrared energy, such as a radiant 
room heater, is in the room.
These conditions commonly cause problems for most 
infrared-controlled equipment. Try the following:

The remote control unit’s batteries may be low on power; replace 
them.

Dim the ambient lighting and/or turn off any fluorescent lights.

Close any window coverings and/or move the projector out of 
direct sunlight.

Turn off other equipment that emits infrared energy.
If the remote control still does not work properly, remember you can 
always control your computer-based presentation directly from the 
computer, even in an environment containing one of the conditions 
listed above.
