Software Overview

Advantech offers device drivers, SDKs, third-party driver support and application
software to help fully exploit the functions of your DAQ devices. All these software
packages are available on Advantech website: http://www.advantech.com/.
The Advantech Navigator is a utility that allows you to set up, configure and test your
device, and later stores your settings in a proprietary database.
1. To set up the I/O device for your card, you could first run the Advantech Naviga-
tor program (by accessing Start/Programs/Advantech Automation/DAQNavi/
Advantech Navigator). The settings could also be saved to XML file, that can be
loaded in the applications using LoadProfile API.

Installed Device tree view. If the software and hardware installation are com-
pleted, you will see the device in the Installed Devices list.
