Features
Intel’s Desktop Processor Socket LGA 1155
By using the latest generation of Intel’s desktop processors and chipsets, code named
Sandy Bridge, the J2 485 supports a very wide range of processors. By taking advantage
of J2’s vast experience with notebook, desktop, and POS computer designs, we have
combined the features of all three for an optimal POS system design. The result is a POS
system that can utilize a desktop chipset that draws very little power and generates a low
amount of heat, similar to mobile chipsets and processors.
Notebook quality components are used in the processor, chipset, and power supply
circuitry, allowing for reduced heat generation and minimal power usage. Additionally,
the J2 485 takes full advantage of the low power features built into the Intel processor
and chipset to further reduce heat.
Hot Swappable RAID / Quad Hard Drives
Like the J2 650, the first integrated POS system on the market to offer a hot swappable
RAID feature, the J2 485 also supports this feature. The four internal 2.5 inch SATA hard
drives can be configured as a RAID array which gives true fault tolerance to the hard
drive subsystem.
DVD/CD Optical Drive
The J2 485 supports standard one DVD/CD optical drive with read/write capability.
Powered USB Ports / Power Port
Addressing the need for additional power ports, the J2 485 supports six +12V and one
+24V Powered USB port. The J2 485 can take advantage as well of the growing
availability of Powered USB products on the market.
In addition to the three Powered USB ports, the J2 485 also supports five powered serial
ports, VGA +12V power, a +24V printer power port, and four standard 2.0 USB ports.
By using a combination of all these powered ports, most all additional external power
supplies for devices such as monitors, scales, “Chip and Pin” devices, scanners, and many
others can be eliminated. This greatly saves space and reduces cost, cables and power
consumption and in most installations this means that only one AC power point is
needed. In addition, with the J2 optional UPS, all these devices will stay powered during
a power outage.

Version 1.0 May 19, 2012

UPS
Not your ordinary UPS, the J2 485 UPS is a DC, not an AC UPS. The UPS replaces the
internal power supply. Unlike an AC UPS the J2 UPS makes the 485 work more like a
notebook computer. In addition to running the J2 485 for up to one hour, the UPS will run
all the POS peripherals attached to the 485, including the printer. Because of the unique
design of the J2 UPS and power supply, the need for special AC power conditioning
devices is eliminated.
Printer Power Port
The 24 volt Printer Power Port can power most POS printers on the market, including the
popular Epson line of printers. When used along with the J2 UPS, if a power outage
should occur, the POS terminal can still operate and print receipts for up to one hour.
Also, when the J2 485 is turned off the printer is turned off also. This is very useful when
the auto power on/off feature of the 485 is used. This also applies to the +24V Powered
USB port.
Cooling System
Great attention was paid to the thermal solution of the J2 485; it is truly a unique feature.
The 485 can run as a fan-less or fan-cooled system. Because of the very wide range of
processors supported, thermal loads can range from 5 watts up to as high as 95 watts and
the J2 485 was designed to handle these thermal loads while still being super quiet. Two
smart fans are used in conjunction with an Embedded Controller (EC) to ensure that the
fans run at the lowest possible speed while still providing proper cooling. Fan speed
changes are controlled to produce the smallest acoustical signature possible. The J2 485
fans are the type used in Blade Servers and have a speed range from 3500~10,000 rpms
running at very high torque.
Fan-Off Mode
When using the i5 or lower performance processors, the J2 485 can run in a fan-off
configuration. In this mode the 485 is a fan-less convection-cooled device. This fan-less
operation may be required for high dust or other special environments.
This feature is unique to J2 and was supported by the J2 650 “Green Mode”. With the J2
485’s “Fan-Off” mode, the power is also greatly reduced by the nature of the processor
used, thereby reducing power consumption and further reducing the unit carbon footprint.
Versatility
The word versatility is the perfect choice word to describe the unique combination of
desirable features designed in to the powerful new J2 485 retail unit. The 485 is not just
one product, but a full product range contained all in one system. From fan-less thin
client to Quad Core RAID Server - the robust J2 485 does it all, with great reliability.

System
Configurations
The J2 485 can be ordered or upgraded to many possible configurations. Selecting the
right combination of memory, processor, hard or solid state drive(s), and software drivers
can dramatically change the performance of the 485 system. For many users the standard
G530 2.4GHz dual core processor and 2GB of memory is perfect, as this is already more
powerful than most all POS systems; however some applications may require more horse
power. In this case the J2 485 could be configured with a quad core i5 or i7 processor.
J2 will be happy to help you determine what you require from the J2 485 to have the best
performance for your customer needs. For example, more memory may be added, or
sometimes a quad core processor and dual HDD with RAID can all be included. The J2
485 can do it all, low end to high end, and at a very reasonable and cost effective price.
Processor Support
The J2 485 supports a very wide range of Intel processor; each provides a different price
performance level. From Celeron dual core, Pentium dual core and -3, i5 and i7 dual a
quad core, with processor speeds from 2.4GHz to 3.4GHz, these are all supported by the
485.
The J2 485 comes standard with the Intel dual core 2.4GHz G530 processor, though it
can also be ordered with a different processor type if desired. The processor can be easily
upgraded by a qualified technician. The J2 485 uses the Intel defined LGA1155 socket.
Intel is constantly adding new processors, so please check with J2 for any additions since
publication of this manual.
The large heat sink, cooling fans, and fan controller (shown below) are designed to keep
everything running cool, quiet and reliably with the supported processors.

I/O Ports
Most I/O ports are accessible at the back of the unit. The case extends over the cables to
protect them when the computer is located against a wall. Cutouts in the case allow for
routing of the cables in any direction.
I/O Panel
Off / On Buttons
The J2 485 has two power buttons, one in the front of the unit and one in the back of the
unit. The front panel Off / On switch is slightly recessed to prevent accidental powering
off. The function of the button can be controlled by the OS. If the 485 hangs for some
reason it can always be powered off by holding the Off / On button in for six seconds.
The J2 485 also supports the following: Restore on AC On power loss, Wake On LAN,
and Wake On RTC alarm features to control the system power up.

Front Panel LEDs
There are two front panel LED indicators, one green/amber LED and one blue LED. The
blue LED is active when either the HDD/SSD are being accessed. The green/amber LED
displays green when the unit is powered up, and shows amber when the unit is powered
down, and AC power applied indicates either stand-by or sleep mode.
Hard Disks
Up to four 2.5 inch SATA hard drives (HDD) or solid state drives (SSD) are supported.
These drives can be configured as standard hard drives or as a RAID array. The SATA
interface can support data transfer rates up to 3.0GB/s and supports AHCI and Hot
Swapping of hard drives.
Two of the four drive locations can be accessed from the front of the unit. With the front
panel key in the unlocked position the drive access door can be opened and easily
accessed with no tools. Just use the pull tab to slide the drives in and out

The other two drives can easily be accessed by removing the top cover of the unit. The
cover can be removed without tools, as shown later in this manual. Once the cover is
removed from the HDD/SSD, the locking tab is moved to the vertical position, please see
below:
A carrying tray (four of which are supplied with the J2 485) fits onto a new drive without
tools. The drive can easily be slid into the drive bay by using the plastic pull tab. In a
RAID 1 configuration, a drive can be hot swapped, removed, or inserted with the power
on (see section on RAID setup).

Video Ports
A standard PC VGA video port is supported on the J2 485 and can be set as the primary
or secondary display. The VGA video port has an industry standard HD DB15 connector.
When used with some J2 monitors the display can be powered by the J2 485 through this
connector.
The J2 485 also supports the newer digital video standard Display Port connector. This
connector supports a Display Port monitor or a HDMI display or DVI monitor. When
used with HMDI or DVI displays, a passive adaptor cable is used. When used with a
HDMI display, Audio is supported via the same HMDI cable.
The secondary video displays can be configured as a Twin, Intel Dual Display Clone, or
Extended Desktop. Most all monitor resolutions from 640 x 485 to 2560 x 2048 are
supported.
Both ports can be used at the same time and either display can be configured as the
primary display.
VGA and DisplayPort Video Ports (see below):

Serial ports
The J2 485 has five external RS232 serial ports, all of which can be powered. The serial
ports are standard RS-232 ports with a DB9 male connector. I in a normal configuration,
serial ports are mapped to COM 1-5.
There also four internal serial ports, one of which is used for the resistive touch controller
and the others are reserved for other internal options.
COM ports 1-5 can supply power to an external device when required, like the optional
J2 Customer Display. COM 1 can supply +5 volt and COM 2-5 supply +12 volts. The
voltage is supplied on pin 9 (RI) of the DB9 connector. The maximum current is 1000ma
and is over-current protected. A BIOS setting is used to enable the voltage on each port.
J2 does not normally recommend using the +5 volt option on COM 1 and it is only there
for some legacy devices. The problem is that it is easy for a +5 volt device to be plugged
into a +12 enable serial port by mistake, which will burn out the +5 volt device. A good
alternative to powering a +5 volt serial device, or any +5V device would be to use power
from an unused USB port. Cables for this are readily available (see below):
