Connecting to External EquipmentConnecting to an External Monitor
Computer images being input to the Computer1 input port can be 
displayed on an external monitor and the screen at the same time when 
connected to the projector. This means that you can check projected 
images on an external monitor when giving presentations even if you 
cannot see the screen.
Connect to an external monitor using the cable supplied with the monitor.
Connecting to External Speakers
You can connect speakers with built-in amplifiers to the projectors Audio 
Out port to enjoy a fuller quality of sound.
Connect with a commercially available audio cable (pin plug W 3.5 mm 
stereo mini plug and so on). Use an audio cable compatible with the 
connector on the external speakers.
q
 Component video signals and images connected to the 
Computer2 port, Video port, and S-Video port cannot be 
output to an external monitor.
 The setting gauge for Keystone, the configuration and 
help screen, and so on are not output to an external 
monitor.

GlossaryThis section briefly explains terms that are used with the projector and difficult terms that are not explained in the text of this guide. For details, 
refer to other commercially available publications.
AMX Device Discovery
AMX Device Discovery is a system setup technology developed by AMX Corporation. Using the AMX control system, devices to be 
controlled in the system can be easily set up.
Epson has adopted this technologys protocol, and has implemented a setting whereby this protocols functions can be enabled (ON). For 
details, refer to the AMX website.

Aspect ratio
The ratio between an images length and its height. Screens that appear wide, with a width to height ratio of 16:9 or 16:10, are known as 
wide screens. The aspect ratio for standard images is 4:3. 
Component Video
A video signal which has the luminance component and color component separated to provide better image quality. 
Refers to images that consist of three independent signals: Y (luminance signal), Pb and Pr (color difference signals). 
Composite video
Video signals that have the video brightness signals and color signals mixed together. The type of signals commonly used by household 
video equipment (NTSC, PAL, and SECAM formats). The carrier signal Y (luminance signal) and chroma (color) signal that are 
contained in the color bar are overlapped to form a single signal.
Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased to make text and graphics stand out more 
clearly, or to make them appear softer. Adjusting this particular property of an image is called contrast adjustment. 
DHCP
An abbreviation of Dynamic Host Configuration Protocol, this protocol automatically assigns an IP address
g to equipment connected to 
a network.
Dolby Digital
A sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format that uses two speakers. Dolby Digital is a 6-
channel (5.1-channel) system which adds to this a center speaker, two rear speakers, and a sub-woofer. 
Gateway address
This is a server (router) for communicating across a network (subnet) divided according to subnet masks
g.
HDTV
An abbreviation for High-Definition Television that refers to high-definition systems which satisfy the following conditions. 
 Vertical resolution of 720p or 1080i or greater (p = progressive
g, i = interlace
g)
 Screen aspect ratio
g of 16:9 
 Dolby Digital
g audio reception and playback (or output) 
Interlace
A method of image scanning whereby the image data is divided into fine horizontal lines that are displayed in sequence starting from left 
to right and then from top to bottom. The even-numbered lines and odd-numbered lines are displayed alternately. 
IP address
A number to identify a computer connected to a network.
Progressive
A method of image scanning whereby the image data from a single image is scanned sequentially from top to bottom to create a single 
image. 
Refresh rate
The light-emitting element of a display maintains the same luminosity and color for an extremely short time. Because of this, the image 
must be scanned many times per second to refresh the light-emitting element. The number of refresh operations per second is called the 
Refresh rate and is expressed in hertz (Hz). 
SDTV
An abbreviation for Standard Definition Television that refers to standard television systems which do not satisfy the conditions for 
HDTV
g High-Definition Television.  
						

							Glossary

SNMP
An abbreviation for Simple Network Management Protocol, which is the protocol for monitoring and controlling devices such as routers 
and computers connected to a TCP/IP network.
SNMP Trap IP address
This is the IP address
g for the destination computer used for error notification in S NM P
Squeeze mode
In this mode, wide-screen images in 16:9 mode are compressed in the horizontal direction so that they are stored on the recording 
medium as 4:3 images. 
When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format. 
sRGB
An international standard for color intervals that was formulated so that colors that are reproduced by video equipment can be handled 
easily by computer operating systems (OS) and the Internet. If the connected source has an sRGB mode, set both the projector and the 
connected signal source to sRGB.
Subnet mask
This is a numerical value that defines the number of bits used for the network address on a divided network (subnet) from the IP address.
SVGA
A type of video signal with a resolution of 800 (horizontal) ^ 600 (vertical) dots that is used by IBM PC/AT-compatible computers. 
S-Video
A video signal which has the luminance component and color component separated to provide better image quality. 
Refers to images that consist of two independent signals: Y (luminance signal) and C (color signal). 
SXGA
A type of video signal with a resolution of 1280 (horizontal) ^ 1024 (vertical) dots that is used by IBM PC/AT-compatible computers. 
Synchronization
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the resulting 
images are not of a good quality. The process of matching the phases of these signals (the relative position of the crests and the troughs in 
the signal) is called Synchronization. If the signals are not synchronized, flickering, blurriness, and horizontal interference occur. 
Tracking
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the resulting 
images are not of a good quality. The process of matching the frequency of these signals (the number of crests in the signal) is called 
Tracking. If tracking is not carried out correctly, wide vertical stripes appear in the signal. 
VGA
A type of video signal with a resolution of 640 (horizontal) ^ 480 (vertical) dots that is used by IBM PC/AT-compatible computers. 
WXGA
A type of video signal with a resolution of 1280 (horizontal) ^ 800 (vertical) dots that is used by IBM PC/AT-compatible computers.
XGA
A type of video signal with a resolution of 1024 (horizontal) ^ 768 (vertical) dots that is used by IBM PC/AT-compatible computers.

ESC/VP21 CommandsCommand List
When the power ON command is transmitted to the projector, the power 
turns on and it enters warm-up mode. When the projectors power has 
turned on, a colon : (3Ah) is returned. 
When a command is input, the projector executes the command and 
returns a :, and then accepts the next command. 
If the command being processed terminates due to a problem, an error 
message is output and a : is returned. * Add a Carriage Return (CR) code (0Dh) to the end of each command and 
transmit.

PJLinkPJLink Class 1 was established by the JBMIA (Japan Business 
Machine and Information System Industries Association) as a standard 
protocol for controlling network-compatible projectors as part of their 
efforts to standardize projector control protocols.
The projector complies with the PJLink Class 1 standard established 
by the JBMIA.
It complies with all commands except for the following commands 
defined by PJLink Class 1, and agreement was confirmed by the 
PJLink standard adaptability verification.
