Susi Utilities - Advantech MIO-2260 User Manual

4.3.2.5 The Watchdog API
A watchdog timer (abbreviated as WDT) is a hardware device which triggers an
action, e.g. rebooting the system, if the system does not reset the timer within a spe-
cific period of time. The WDT API in SUSI provides developers with functions such as
starting the timer, resetting the timer, and setting the timeout value if the hardware
requires customized timeout values.
4.3.2.6 The Hardware Monitor API
The hardware monitor (abbreviated as HWM) is a system health supervision capabil-
ity achieved by placing certain I/O chips along with sensors for inspecting the target
of interests for certain condition indexes, such as fan speed, temperature and voltage
etc.
However, due to the inaccuracy among many commercially available hardware mon-
itoring chips, Advantech has developed a unique scheme for hardware monitoring -
achieved by using a dedicated micro-processor with algorithms specifically designed
for providing accurate, real-time and reliable data content; helping protect your sys-
tem in a more reliable manner.
4.3.2.7 The Power Saving API
1. CPU Speed
– Make use of Intel SpeedStep technology to reduce power consumption. The
system will automatically adjust the CPU Speed depending on system load-
ing.
2. System Throttling
– Refers to a series of methods for reducing power consumption in computers
by lowering the clock frequency. APIs allow the user to lower the clock from
87.5% to 12.5%.

SUSI Utilities

4.3.3.1 BIOS Flash
The BIOS Flash utility allows customers to update the flash ROM BIOS version, or
use it to back up current BIOS by copying it from the flash chip to a file on custom-
ers'disk. The BIOS Flash utility also provides a command line version and API for fast
implementation into customized applications.
4.3.3.2 Embedded Security ID
The embedded application is the most important property of a system integrator. It
contains valuable intellectual property, design knowledge and innovation, but it is
easily copied! The Embedded Security ID utility provides reliable security functions
for customers to secure their application data within embedded BIOS.
4.3.3.3 Monitoring utility
The Monitoring utility allows the customer to monitor system health, including volt-
age, CPU and system temperature and fan speed. These items are important to a
device; if critical errors happen and are not solved immediately, permanent damage
may be caused.
4.3.3.4 eSOS
The eSOS is a small OS stored in BIOS ROM. It will boot up in case of a main OS
crash. It will diagnose the hardware status, and then send an e-mail to a designated
administrator. The eSOS also provides remote connection: Telnet server and FTP
server, allowing the administrator to rescue the system.
