# P12 Touch-Interactive Projector Distance and Positioning Calculator

```P12 Touch-Interactive Projector Distance and Positioning Calculator
Preface
This document provides distance calculation and positioning information for the P12 touch-interactive
projector. The distance calculation and positioning information for the pen-interactive and non-interactive
P12 models is on a separate document titled “P12 Pen-Interactive Projector Distance Calculator.”
Introduction
This document enables determining proper wall bracket placement for the several models of P12
projector: WXGA, 16:9, and Ultra-Wide. It is essential to reference the correct table for the projector
model and measurement units, millimeters or inches, when placing the wall bracket.
The most critical dimensions are:


Distance from top of the wall plate to the top of the image (O).
o Note that complying with the prescribed dimensions will produce a space between the
bottom of the laser curtain module and the top of the displayed image.
o This space is essential for proper touch interactivity.
o The space is not required for non-interactive or pen-interactive implementations.
Offset from center – the left edge of the wall bracket must be 0.5 in./13mm to the right of the
image center as shown in figure 1 below.
Mounting Arms
The WallMount-P12U is the wall mount model Boxlight bundles with the P12 Ultra-Wide model because
this mount provides the additional arm length required to produce the largest specified diagonal image
size.
The WallMount-P12W is the wall mount model bundled with the WXGA and 16:9 model because this
mount provides the arm length is sufficient to produce the largest specified diagonal image size.
Installation process





Identify the correct version of the “Wall Mount Measurement Chart” below
Position the wall plate to the wall as shown in Figures 1 below and the appropriate chart
o Position at the specified height above the top of the projection surface and
o Position the left edge of the wall bracket offset from the center of the image as shown in
Figure 1
Attach the arm to the wall plate
Attach the projector to arm
Alignment
o Position the projector at the specified distance from the projection surface
o Adjust focus using the lever at the left edge (the lens side) of projector
o Adjust physical positioning and alignment as shown in Figures 2 and 3 below
