Projection Angle for Ceiling Mounted Projectors
Make sure your projector is positioned so that the interactive module will not interfere with the projected
image. You may need to adjust your projector's position to avoid possible interference.
Refer to the table on page 9 or 10 and formulas on page 11 to determine whether you need to adjust
your ceiling-mounted projector's position. For additional support tools and information, visit
www.epson.com/support (U.S.) or www.epson.ca/support (Canada).
Note
No matter where your projector and interactive module are located, the person using the pen will cast a shadow on
the image. The shadow will not interfere with the interactive function, as long as the signal itself is not blocked.
Determining the Height of the Interactive Module
You need to determine the required distance between the top of the image area and the bottom of the wall
plate, based on the diagonal image size and aspect ratio. This distance indicates how high you need to
mount the interactive module on the wall.
1
Determine the aspect ratio of your whiteboard or projected image. For new projectors and computers,
this will most likely be WXGA (16:10). For older equipment, this will most likely be XGA (4:3).
If you are planning to project on a whiteboard, check the measurements on page 9 or 10 and select the
image size that most closely matches your whiteboard. If the size and aspect ratio of your board do not
not match any of the listed dimensions, the image may not fill the entire board.
