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.

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.
