							The Palm Pilot Control Utility has been designed to allow extensive operational
control of the projector without using the on-screen menu system.
The Palm Pilot connects to the projectors computer port via a straight wired 9 pin
male to female cable and uses the following settings - 19,200 baud, 8 bits, no parity,
1 stop bit, no flow control.
Assuming the connection to the projector is set up correctly, when you activate the
Power Control Utility the Function screen will be displayed. This screen allows
selection between control of DV Series or GV Series projectors or to use the Lens
and Lumen Calculation functions.
Upon selection of a projector, the utility will establish a connection with the 
projector and the Main Screen will appear providing the main controls - Chan,
Lamp, PMute, Addr, Quit, Query, Pic adj and Geo Adj.
Chan- allows you to directly select a projector channel. To select channels one
through nine the corresponding button should be used. To select channels 10 and
above, first press 10+ then the sequence for the required channel. The current 
channel (or the status of the channel change) will be displayed above the channel
selection buttons.
Lamp- sets the lamp power to high, low or off. The current setting will be 
displayed above the lamp power buttons.
PMute- sets the picture muting. The current setting will be displayed.
Addr- allows you to define the projector address you want to control when using
multiple projectors.
It is only possible to query one projector at a time with the Palm Pilot program and
the addresses of the individual projectors must be pre-defined before they can be
controlled. If you define an address of 0 with multiple projectors connected, your
return values will be invalid.

							Query - allows you to request the projectors current settings. To the left of this 
button a timer is displayed. When this timer reaches 0 the utility automatically
queries the projectors settings and sends an OSD Off command to prevent any
menus being accidentally displayed on screen.
Pic Adj- displays a new screen with provision for brightness, contrast, sharpness,
hue, saturation and colour temperature adjustment.
Geo Adj- displays a new screen with provision for size, position, pixel count and
pixel phase adjustment.

							The projectors arc lamp emits a luminous fluxmeasured in lumens. This flux is
directed at the screen and illuminates it, the illuminance(E) can be measured in Lux
(lumens/m2) or Foot Candles (lumens/ft
2). The illuminanceof the screen is 
calculated by dividing the incident flux by the illuminated screen area.
The brightness of the screen, known as the screen luminance(B) is determined by
the amount of light reflected from it (or transmitted through it if using a rear 
projection screen). If the screen is diffuse, the incident light is reflected into a 
hemisphere. If the screen has a reflectivity(R), the screen luminancein candela/m
2
is given by (R x E) / ¹, where E is measured in Lux. If E is measured in Foot-
Candles, the screen luminanceis in Foot-Lamberts, and is given by R x E.
Examples:
1) A 6 x 4 6 diffuse screen, with a reflectivity of 0.8 is illuminated by a projector
emitting 3000 lumens.
The screen illuminance (E) = F / A = 3000 / 27 = 111 Foot-Candles
The screen luminance (B) = R x E = 0.8 x 111 = 89 Foot Lamberts
2) A 4m x 3m screen with a reflectivity of 0.85 is illuminated by a projector 
emitting 3500 lumens.
The screen illuminance (E) = F / A = 3500 / 12 = 292 Lux
The screen luminance (B) = (R x E) / ¹= (0.85 x 292) / ¹= 79 Candela/m2

							A DMD™ (Digital Micromirror Device™) is a true digital light modulator and
utilises 1,310,720 moving aluminium mirrors, with each one representing a pixel in
the final projected image. Each mirror is suspended over address electrodes by a
torsion hinge between two posts. Depending on the voltage polarity applied, each
mirror will either tilt to left or to the right. When light is applied to the complete
DMD™, only the light redirected from a mirror tilting to the left is projected.
The projector optically filters white light from the lamp into its constituent red,
green and blue. Each colour illuminates a separate DMD™ whose modulated output
is then recombined with the other two to form the projected full colour image.

							The mirrors in the DMD™ are arranged in a 1280 x 1024 array allowing images of
all aspect ratios to be displayed. However, the proportion of DMD™ effectively
used will differ depending on the aspect ratio of the image. The diagrams below
show the DMD™ usage for each aspect ratio (4 x 3, 5 x 4, 8 x 5, 14 x 9 and 16 x 9)
with the shaded areas representing redundant mirrors.
