Susi Utilities - Advantech PCM-3363 User Manual

4.3.2.6 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 time-out value if the hardware
requires customized time-out values.
4.3.2.7 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 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; helping protect your system in a
more reliable manner.
4.3.2.8 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
loading.
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

PCM-3363 supports software Utility including Embedded Security ID, Monitoring util-
ity, eSOS.
4.3.3.1 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.
4.3.3.2 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.
4.3.3.3 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 for remote connection via Telnet server and
FTP server, allowing the administrator to rescue the system.
Note! eSOS Utility support on PCM-3363 requires BIOS modification.
