Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
 To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
 Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive electronic components.

Computer on Module.
Sections include:
 Introduction
 Specification
 Functional Block Diagram
1.1 Introduction
SOM-5894 is a COM-Express Basic module with pin-out Type 6 that fully complies
with the PICMG (PCI Industrial Computer Manufactures Group) COM.0 R2.1 specification. The CPU module incorporates an Intel 4th Generation Core i processor, PCH
QM87, and other peripheral chips. The Intel latest processor uses 22nm and 3D Trigate transistor technologies that brings 13% performance improvement over previous versions, and integrates a powerful Intel HD Graphic 4600 as well as DX11.1,
OpenCL1.2, OpenGL4.0 API enabling better display configurations with no bandwidth limitations. With Intel PCH QM87, SOM-5894 provides advanced interfaces
such as PCI Express Gen 3, SATA Gen 3, and USB3.0. Moreover, PCIe x16 can be
used in combination of x4 or x8 to make it more flexible.
Advantech iManager 2.0 was invented to satisfy a lot of embedded application
requirements such as multi-level watchdog timer, voltage and temperature monitoring, thermal protection and mitigation through processor throttling, LCD backlight on/
off and brightness control, and embedded storage. Combining Advantech SUSI
Access, it can remotely monitor and control devices via the internet for easy maintainance. All Advantech COM Express modules integrate iManager and SUSI Access
to benefit our customer’s applications.
With top performance and lower power consumption, various extensions and I/O
interfaces, SOM-5894 is suitable for computing intensive design, thermal sensitive
design, graphics/media insensitive design, and I/O demanding applications.

S/W Introduction & Installation
Advantech's platforms come equipped with iManager, a micro controller that provides
embedded features for system integrators. Embedded features have been moved
from the OS/BIOS level to the board level, to increase reliability and simplify integration. iManager runs whether the operating system is running or not; it can count the
boot times and running hours of the device, monitor device health, and provide an
advanced watchdog to handle errors just as they happen. iManager also comes with
a secure & encrypted EEPROM for storing important security key or other customer
define information. All the embedded functions are configured through API and provide corresponding utilities to demonstrate. These APIs comply with PICMG EAPI
(Embedded Application Programmable Interface) specification and unify in the same
structures. It makes these embedded features easier to integrate, speed up developing schedule, and provide the customer's software continuity while upgrade hardware. For more details of how to use the APIs and utilities, please refer to Advantech
