Epson Powerlite 715c Multimedia Projector Users Guide

							12Setting Up the Projector
Connecting to a Laptop Computer
You can connect the PowerLite projector to any computer that has a 
standard video output (monitor) port, including PC notebook and 
laptop computers, Macintosh PowerBooks, and hand-held devices.
Connecting the Computer Cable
Before you start, make sure your computer and the projector are 
turned off.
1. Connect one end of the computer cable to the projector’s 
Computer port.
 
2. Connect the other end of the computer cable to your laptop’s 
video-out or monitor port.
If you’re using a PowerBook and you can’t connect the cable, you 
may need to use the Macintosh desktop adapter as shown on 
page 111 (available from EPSON; see page 8). 
3. Tighten the screws on the connectors.
note
To connect to desktops and 
other computer systems, see 
Appendix A. If you have an 
iBook with an RCA video- 
out port, follow the 
instructions for connecting to 
a video device on page 16.
note
Laptop configurations vary. 
See your computer manual for 
the location of the ports 
needed to connect your 
projector. 
						

							Setting Up the Projector13
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 20 for instructions.
Connecting the Cable for Remote Mouse 
Control
Using the remote control as a wireless mouse lets you click through 
slideshow-style presentations, such as PowerPoint, from up to 30 feet 
away (for details, see page 38). This gives you more flexibility in 
delivering your presentation, since you won’t need to stand near your 
computer. 
You’ll use different cables and different ports on the projector, 
depending on whether your laptop has a round mouse port or a flat 
USB mouse port.
1. Locate the cable you need, depending on whether your laptop has 
a round PS/2 mouse port or a flat USB port. 
2. Connect one end of the appropriate mouse cable to the projector’s 
Mouse/Com port, as shown. 
3. Connect the other end of the cable to the external mouse port or 
USB port on your laptop.
note
If you’re using a PowerBook 
that has a round mouse port, 
you’ll need a Macintosh 
mouse cable. See your 
projector dealer to obtain the 
correct cable.

							14Setting Up the Projector4. If necessary, configure your laptop to work with an external 
mouse. 
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 20 for instructions.
Amplifying Computer Audio
Your laptop probably has its own sound system; however, it may not 
be adequate for your presentation. If you need more volume or better 
sound quality, you can connect a computer audio cable to take 
advantage of the projector’s built-in amplifier and speaker. You can 
obtain a computer audio cable (3.5-mm stereo miniplug cable) from a 
computer or electronics dealer.
1. Connect one end of the audio cable to the 
Audio In jack on the 
projector.
  
2. Connect the other end of the audio cable to your laptop’s  
headphone jack or   audio-out jack. (Jack locations vary; see 
your computer manual if you’re not sure of which jack to use.)
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 20 for instructions.

Connecting to Video Sources
You can connect a DVD player, VCR, camcorder, laser disc player, 
digital camera, or any other compatible video source to your projector.
The projector supports HDTV, NTSC, PAL, and SECAM, and 
automatically detects the video format. 
The projector can receive composite video, S-Video, and component 
video. You can connect the projector to one or two of these video 
sources at the same time; however, you can only use audio from one 
source at a time.
The type of cable you use depends on whether you have composite 
video, S-Video, or component video.

For composite video, use the RCA AV cable included with the 
projector. 

For component video, you will need the optional EPSON 
component video cable (D-sub 15-pin to 3BNC, ELPKC19). 

For S-Video, use the S-Video cable supplied with your video 
device or obtain one from your electronics dealer. 
See the following illustration if you’re unsure of which type of 
connectors you have.
If more than one type of connector is available, S-video and 
component video provide higher quality than composite video.
Follow the instructions below for your type of connection.

support TV antenna cable

Before starting, make sure the projector and your DVD player or 
other video source are turned off.
1. Connect the yellow plug on one end of the AV cable to the 
projector’s yellow 
Video jack. 
2. Connect the other end of the cable to the video-out jack on your 
video source.
3. Connect the AV cable to the left and right Audio jacks on the 
projector (insert the white plug into the 
L port and the red plug 
into the 
R port). 
4. Connect the plugs at the other end of the cable to the audio 
output jacks on your video source.

Connecting S-Video 
If your video source has an S-Video jack, you can use it to project a 
higher quality video image. However, you’ll need an S-Video cable, 
which may be included with your video source, or may be purchased.
Before starting, make sure the projector and your DVD player or 
other video source are turned off.
1. Insert one end of an S-Video cable into the projector’s 
S-Video 
connector. 
2. Insert the other end into the S-Video output port of your video 
source.
3. Connect the RCA AV cable to the left and right 
Audio jacks on 
the projector. (Match the red and white plugs to the red and 
white jacks; you won’t need to use the yellow plug.)
4. Connect the plugs at the other end of the cable to the audio 
output jacks on your video source.

							18Setting Up the Projector
Connecting Component Video Cables
If your video source has component video connectors, you can use 
them to project a higher quality video image. However, you’ll need a 
component video cable (D-sub 15-pin to 3BNC), which can be 
purchased from EPSON (ELPKC19).
Before starting, make sure the projector and your DVD player or 
other video device are turned off.
1. Connect the large end of the component video cable to the 
projector’s 
Computer/Component Video port.
2. Insert the three ends of the component video cable into the 
R, G, 
and 
B ports on your video source.  
3. Connect the RCA AV cable to the left and right 
Audio jacks on 
the projector. (Match the red and white plugs to the red and 
white jacks; you won’t need to use the yellow plug.)
4. Connect the plugs at the other end of the AV cable to the audio 
output jacks on your video source.     
5. After you turn on the projector, use the Video menu to set the 
Input Signal to 
YCbCr or YPbPr. See page 74 for more 
information.

Using the Projector19
Using the Projector
Once you’ve set up the projector, you’re ready to turn it on, adjust 
the image, and give your presentation. You can use the built-in 
EasyMP system to project without connecting to other equipment, as 
described in Chapter 5. Or, you can connect the projector to a 
computer or video source, as described in Chapter 1 and Appendix A.
Although you can operate the projector without it, the remote control 
lets you use additional features. See Chapter 3 for instructions on 
using the remote. This chapter covers the following:

							20Using the Projector
Turning On Your Equipment
Make sure your projector (and optional equipment) are set up and 
connected correctly, as described in Chapter 1 or Appendix A. Then 
turn on your projector, as described below, followed by any 
equipment you’ve connected to it. You can turn on your computer 
and video equipment in any order, but if you have both a computer 
and video source connected, you may have to switch to the desired 
source as described on page 23. 
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Connect one end of the power cord to the projector’s power inlet. 
2. Connect the other end to a grounded electrical outlet. 
The power light on top of the projector turns orange, indicating 
that the projector is receiving power but not yet turned on.  
3. Use the tab on the lens ring to rotate the ring and extend the lens.
