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.
