1.1 Introduction
The LGX AU910 and AU912 are targeted at many different applications.
They easily meet the challenges of specic markets, such as advanced
kiosks, digital signage, GSM Server, and harsh environment applications.
All-In-One Platform
The entire unit is fully integrated in order to provide a plug-and-play device.
Compact-sized
The kernel of the AU910/AU912 is a non-standard form factor embedded
mainboard. The whole system takes up minimal space.
Fanless and Modular CPU Board
By using a low power processor, the system does not have to rely on fans,
which are often unreliable and cause dust to circulate inside the equipment.
The modular design facilitates maintenance or possible upgrades on the
CPU board. It can be easily modied to t many different applications ac-
cording to customers' requests.
Powerful Communication Capability
The AU912 provides COM, LPT, Ethernet, USB, Mini Card slot, DVI and
Digital I/O expansion slot.
Numerous Display/Video Output
Integrated with Intel® HD Graphics core, you receive improved graphics
and 3D rendering performance and supports numerous display/video output
options includes VGA and DisplayPort.
Advanced Storage Solution
The AU910 and AU912 come with a CFast slot, which offers a better, faster
and more cost-effective expansibilities for various applications.
Trustworthy
The onboard Watchdog Timer can invoke an NMI or system RESET when
your application loses control over the system.
