Native resolution—The resolution of a digital flat panel display that actually describes how many pixels are in
each row and column of the display, and which is the resolution that the display is optimized for.Your 12" Aspen
touch monitor has a native resolution of 800x600, which means that the LCD panel has 800 pixels on each row,
and has 600 rows.Each element of video information received from the computer/display electronics is assigned
to and displayed by a specific location on the display panel—a pixel.At resolutions other than native (see emulation)
there is not a one to one correspondence between the video information elements and the available pixels on
the display.The display electronics must compensate for this and cannot do a perfect conversion, thus emulation
modes never look as good as images displayed at the native resolution.
Nit—The standard unit of luminance is the candela per square meter (cd/m2), or Nit.
Pixel—Abbreviation for “picture element.”In an electronic display, the smallest complete element of the picture
that contains all possible colors and proper brightness.In your Aspen Touch Monitor, one pixel of the LCD panel
is a square “window,”with an area of about 0.3x0.3mm, containing three smaller windows that pass red, green or
blue light at the appropriate brightness in response to the video signal from the computer.
Polarizer—A thin glass or plastic sheet that filters out light rays of all but a specific orientation.Light passing
through such a sheet is thus polarized.
POS—Acronym for Point Of Sale.
Serial—A data transmission method where each bit (a “1” or “0”) of data is passed sequentially (or serially) over
a single data path (a wire…).The most common standard for this method is called RS232.This is a very common
method of interfacing peripheral equipment to older computers.Today this method is increasingly replaced by
another method called USB (see below).
USB—Acronym for Universal Serial Bus.A common method for interfacing peripheral equipment to computers.
It has the advantages over other serial data transmission standards of higher speeds and the ability to connect
many devices to the same port on a computer.
VESA—Acronym for Video Electronics Standards Association.An industry trade group that promotes interoper-
ability standards within the video and computer industry.The VESA mounting pattern (75 mm) for displays is used
by your Aspen Touch Monitor on the base and chassis, allowing the monitor to be quickly attached to standard
swing arms and mounting plates.
Mounting Template:
A full-sized image of the metal base plate for the touch monitor is included with this manual, and may be used as
a template for creating mounting holes in a countertop, etc.Electronic versions of this manual include a file that
may be printed to create the same template.Ensure that your printed version is scaled correctly.You may check
the accuracy of your printed template by verifying that the center-to-center distances of the VESA mount pattern
are exactly 75mm or 2.95".
