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 17" Aspen
touch monitor has a native resolution of 1280 x 1024, which means that the LCD panel has 1280 pixels on each
row, and has 1024 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/m
2
), 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 touchmonitor, 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—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—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—Video Electronics Standards Association.An industry trade group that promotes interoperability standards
within the video and computer industry.The VESA mounting pattern (100 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 printing by verifying that the center-to-center distances of the VESA mount pattern are exactly 100mm.
