Value-Added Software Services
Software API are interface that define the ways in which an application program may
request services from libraries and/or operating systems. They provide not only the
underlying drivers required but also a rich set of user-friendly, intelligent and inte-
grated interfaces, which speed development, enhance security and offer add-on
value for Advantech platforms. API plays the role of catalyst between developer and
solution, and make Advantech embedded platforms easier and simpler to adopt and
operate with customer applications. This API and utility is only for XP, so if users
needs Linux version API and utility, then contact an Advantech representative for
support.

PCA-6028 User Manual
General Purpose Input/Output is a flexible parallel interface
that allows a variety of custom connections. allows users to
monitor the level of signal input or set the output status to
switch on/off the device. Our API also provides Programma-
ble GPIO, which allows developers to dynamically set the
GPIO input or output status.
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes
wrong and the system does not recover on its own. A watch-
dog timer can be programmed to perform a warm boot
(restarting the system) after a certain number of seconds.
The Hardware Monitor (HWM) API is a system health super-
vision API that inspects certain condition indexes, such as
fan speed, temperature and voltage.
