INSTALLATION AND SETUP
2.8 Zoom, Focus & Lens Offset
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.
Focus
At the lens opening, turn the focus tab until the image is as sharp as possible.
Lens Offset
To ensure that the image is located as desired, turn either or both of the front screws next to the
lens. The top screw (vertical) will raise or lower the image, the bottom screw (horizontal) will
shift the image left or right. Try to achieve the desired overall image position and best brightness
while obtaining a rectangular image. If the brightness looks uneven, or the edges do not look per-
fectly straight, the projector may not be in the optimal position for your screen. 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.

Serial Port Connections

You may wish to use equipment other than the keypad for controlling the projector or for per-
forming 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 projec-
tor. Note that there are two different types of serial communication ports on this projector as
described below.
If using a computer
RS-232 Ports
From computers or automation systems, connect an RS-232 serial communication cable between
the controlling device and the projector serial port labeled RS-232 IN-this 9-pin D connector port
is located near the bottom center of the projector's rear control panel (see Figure 2.19). Then set
the projector baud rate to match that of the computer or automation system(changing the baud rate
is described in 3.7, Adjusting System Parameters and Advanced Controls).
NOTE: Refer to Appendix D for complete cable wiring details.
