Overview
The J2 225 is a new generation of integrated touch screen Point of Sale computer,
brilliantly designed to be more compact and cost effective, yet rich in features and
versatility. The J2 225 moves away from the traditional POS 4:3 screen form factor and
uses the newer LED backlit 16:9 screen. This allows for a smaller overall physical
footprint yet allows for the display of more onscreen data. Retaining the core features and
capabilities of J2’s other tradition POS products, like the J2 615 and J2 630 units, the J2
225 takes advantage of the newer technologies currently available.
This integrated touch screen computer, like other J2 designs, features an “all-in-the-head”
design, and it also offers the versatility to be used as a counter top unit; or as a wall-
mount or pole-mounted terminal. The new smaller foot print and its unique swing arm,
die cast aluminum base allows for even more flexibility, leaving more counter space for
other uses. With an extremely wide range of adjustable heights and viewing angles, the
versatile J2 225 can be made to work in almost any POS environment. It weighs only
3.7kg and conveniently folds flat for shipping, therefore saving customers tremendously
on shipping and storing costs.
The J2 225 uses the latest Intel Atom dual core Cedarview processors, the 1.86GHz
D2550. Combining this with the Intel NM10 chipset provides excellent performance
capable of running most POS applications with a very low carbon foot print, all at a
competitive and attractive low price.
Even with its small foot print the J2 225 is incredibly feature rich. It comes standard with
2GB of memory, and offers a choice of either a 160GB hard drive or 16GB solid state
drive. Built standard with four serial ports, four USB ports, video output, audio in/out,
gigabit Ethernet, +12V output, as well as other built in peripherals (like MSR, customer
display and more) the J2 225 will perfectly satisfy most POS application requirements,
while looking sleek and elegant in any setting.
The J2 225 is available with your choice of either a zero bezel resistive touch screen or a
multi-touch projected capacitive touch screen. The new zero bezel five-wire resistive
touch screen provides the same quick response and feel of a resistive touch screen
traditionally used in the POS market. The new projective capacitive touch screen option
can be used in environments where multi-touch and gesturing are required, for example,
such as when using the new Windows 8 operating system.
The J2 225 is brilliantly designed to require little or no maintenance. The convection
cooled fan-less design means it can be used in very harsh environments. High dust,
grease or sea air will not affect its operation. High temperatures are also not a problem.
With a quick access HDD/SDD slot, a drive can be changed in just seconds if needed! A
snap-apart design allows the unit to be fully disassembled and assembled in just a few
minutes by just removing a few screws. Also available are optional Snap-on color kits, so
that the J2 225 can be customized to your customer needs.

The J2 225 supports the standard Microsoft operating systems: Windows 7, POSReady 7,
Windows 7 Embedded, XP, POSReady 2009 and XP embedded, as well as the soon-to-
be-released Windows 8. The J2 225 is equally proficient with the many flavors of Linux.

Design Concept J2 225
The J2 225, with its smooth modern appearance and capabilities, is perfectly suited for
most low cost commodity POS touch screen computer markets. The economical price and
outmatched performance will provide a great ROI for the end user, as they find it
extremely dependable as well as very easy to use. MSR and Secondary Display options
make it a perfect fit for companies in the POS markets, as well as for other industries,
including medical and healthcare applications, among many others.
To provide the highest performance at low cost with a long product life the J2 225 unit
design is based on the new Intel Atom Cedarview processor. This new 32nm part has
higher speed and runs on lower power than the current offering of Atom processors for
Intel.
The unit was built using as few screws as possible, providing ease of assembly and
disassembly, a major design achievement. This means that the touch screen, J2 225 panel,
or systems board can quickly be replaced in less than two minutes if needed (however
with the solid reliability of this creative unit, this should not even be necessary.)
A major goal in the enclosure design is to keep the total size of the unit as thin and as
small as possible. The thickness to the head is not much thicker that a standard notebook,
except for a slight bulge in the back where the electronics are located. The aluminum die
cast swing arm and fully adjustable base of the unit not only provide superb flexibility but
can also easily fold flat for shipping. The shipping box for the J2 225 is no bigger than
the size of an average notebook shipping box, which is also about 1/3 to 1/4 the size and
weight of other POS products.
As with all J2 products our ultimate goal is always reliability. Reliability is never
compromised because to reduce any cost at the expense of a dependable product would
be a false economy, and we firmly stand by our outstanding engineering and designs. We
always have our customer’s needs in mind as we move forward, offering the best in the
market today.

Hard Disks
One 2.5 inch SATA hard drive (HDD) or a solid state drive (SSD) are standard with the
J2 225. The SATA interface can support data transfer rates up to 3.0 GB/s. The J2 225
offers standard either a 160GB HDD or 16GB SSD, but can be ordered with other size
HDD or SSD as well. See J2 for details.
The HDD/SSD can be installed or removed in seconds by removing one screw. It is
easily accessed by removing the HDD cover retaining screw and sliding the drive out, the
HDD cover can then be unclipped from the drive.
HDD access panel
HDD slide in-slide out drive bay
Touch Screen
The J2 225 can be ordered with two different touch screen technologies, PCT or TFR.
The PCT unit uses a multi-touch Projected Capacitive Technology touch screen. The PCT
touch screen has no known failure mode-- it does not “wear out.” This screen is
tempered glass and does not reduce the brightness of the J2 225 panel. When operating
in a very high use environment, the PCT is the recommended touch screen technology.
The PCT touch screen will work with most gloves and stylus that are designed to work
with tablet computers, and the screen has a smooth glass surface that is reflective.
The TFR uses a five-wire true flat (zero bezel) resistive touch screen rated at 35 million
touches per point. The resistive technology is very responsive and is the traditional choice
for a hospitality POS system. The screen has an anti-reflective plastic film surface.
Both screens are fully spill proof, dust proof, and can be cleaned with a standard glass
cleaner. The J2 225 touch screen was designed to easily be changed, normally in less than
two minutes. Depending on operating environment and usage, both the Resistive and
PCT touch screens have strengths and weaknesses; therefore J2 offers both touch screen
technologies on the J2 225 unit, providing our customers with a choice for any
application requirement.

System Board
POS computers typically have a lifespan of 10 years or longer, therefore product quality
is of the utmost importance. J2 225 electronics are built with high-end components to
ensure reliability and long lasting product performance.
The system board is designed for quick replacement, with just a few screws and cables to
unplug. The board can be swapped out in less than three minutes.
J2 225 System board
J2 225 Display
The J2 225 offers a 1366 x 768 resolution display with 16.2 Million colors, and a 14 inch
LED backlight with 16:9 aspect ratio screen. The brightness is rated at 220cd/m2. The
Intel controller allows for the display to be rotated to 0, 90, 180 or 270 degrees without
loss of performance. The driver can also scale the display resolution so that it can work
properly with applications written for 1024x768 or 800x600 resolutions.
The J2 225 electronics also supports dimming, and can be controlled directly by
Windows 7 or 8, or with J2 supplied utilities for Windows XP. Dimming levels between
5-100% are supported. A hardware auto dimming feature is built-in to ensure the longest
LED backlight life and to also provide the lowest power usage.

Secondary Video Port
The J2 225 supports the newer digital video standard Display Port connector. This
connector supports a Display Port monitor, HDMI display, DVI or VGA monitor. When
used with HMDI or DVI displays, a passive adaptor cable must be used. When using a
VGA display, an active adaptor is to be used. With HDMI display Audio, support is
provided via the same HMDI cable.
The secondary video displays can be configured as Twin, Intel Dual Display Clone, or
Extended Desktop. Most all monitor resolutions from 640 x 480, up to 2560 x 1600 are
supported.
When the internal secondary J2 225 video display is used the secondary video port is not
available.

Serial ports
The J2 225 unit has four external RS232 serial ports, all of which can supply +12V
power. The serial ports use a ten pin RJ45 connector. The unit comes standard with four
serial cables, three 38cm (15”) RJ45 to DB9 adapter cables, and one 152cm (5’) RJ45 to
DB25 serial printer cable that works with EPSON and EPSON compatible printers.
All serial (COM) ports can be BIOS-enabled to provide +12Vpower to external devices.
This power is supplied via pin 10 of the RJ45 which corresponds to pin 9 on the DB9
adaptor. The maximum current per port is 1 amp, with a total maximum external loading
on the +12V of 3 amps.
A set of stick-on color coded labels are supplied with the cable adaptors, so that the
cables can be marked. This makes it easy to plug the cable back into the correct port,
should you need to service the unit.
