DLV1280 DX User's Manual
For most installations, the
lens surface of the projector
is parallel to the screen—this
prevents major keystoning of
the image (i.e., an image
with non-parallel sides). In
addition, the projector must
be kept level from side-to-
side in order for the lamp to
function safely. To make
small corrections to the projector's level, rotate each leg as necessary to raise or
lower. For angled installations, see "Special Mounting" under 2.3, Projector Position
and Mounting earlier in this section.
Once the projector is properly set up and producing an image, you are ready to make
quick lens adjustments.
Zoom
'
If you have a zoom lens installed, turn the textured ring of the lens barrel to decrease
or increase the size of the image at the current throw distance. NOTE: Do not touch
the lens surface.
'
At the lens opening, turn the focus tab until the image is as sharp as possible.
'
The projector should be positioned so that the lens is centered with the screen. If you
need to offset the image, see 2.3, Projector Position and Mounting for full details.
Lens offset ranges are also listed on page 5-1.
Further display adjustments are available through keypad commands and on-screen
menus—refer to Section 3, Operation.
NOTE: Communication software is required for serial control. Contact your dealer
for details.
You may wish to use equipment other than the keypad for controlling the projector or
for performing other special functions. Such equipment—such as most personal
computers—requires a serial interface for sending and receiving communications
through the serial ports on the projector. Note that there are two different types of
serial communication ports on this projector as described below.
RS-232 Ports
'
From most computers, connect an
computer and the projector serial port labeled
is located near the bottom center of the projector's rear control panel (see Figure
2.22). Then set the projector baud rate to match that of the computer (changing the
baud rate is described in 3.7,Configuring System Parameters).
NOTE: Refer to Appendix D for complete cable wiring details.
