This is the physical component within the projector that creates the image. It can be either an
LCD panel or DMD device.

Calculating Image Size and Throw Distance using Focal Length 
If the throw ratio of the lens is not available then the focal length can be used to calculate the
image size or throw distance, however the dimensions of the display panel are needed.

To calculate the throw distance for a pre-defined image size:

Example
Calculate the throw distance required to give a 2.5m diagonal image. The focal length of the
lens is 44mm and the DMD panel is 20.32mm (Diag)

To calculate the image size from a set distance:

Example
Calculate the image size (diag) at a throw distance of 3m. Focal length is 63.8mm and the
LCD panel is 63.8mm (Diag)

Image and Panel Size must be of the same dimension. i.e. Image and Panel

diagonal measurement OR width measurement.

“Plug and Play” function (when connecting to a 15-pin
terminal)
• 

This projector is compatible with VESA-standard DDC 1/DDC 2B. The projector and a VESA DDC compatible
computer will communicate their setting requirements, allowing for quick and easy set-up.

• 

Before using the “Plug and Play” function, be sure to turn on the projector first and the connected computer last.

Note

• 

The DDC “Plug and Play” function of this projector operates only when used in conjunction with a VESA DDC
compatible computer.

Response code format
Normal response 

Problem response (communication error or incorrect command)

• 

When more than one code is being sent, send each command only after the response code for the
previous command from the projector is verified.

• 

When using the computer control function of the projector, the adjustment values cannot be read by
the computer. Therefore, confirm the values by transmitting the display commands (e.g. “RARE_ _
_0”) for each adjustment menu and checking the values with the on-screen display. If the projector
receives adjustment/setting commands other than menu display commands, it will execute the
commands without displaying the on-screen display.

• 

If an underbar (_) appears in the parameter column, enter a space. If an asterisk (*)
appears, enter a value in the range indicated in brackets under CONTROL CONTENTS.
