Introduction
AS726x

-intelligent Spectral Interface (iSPI) Evaluation Kits provide a platform to evaluate
ams
AS726x products with AS726x – iSPI software running on Windows based personal computer. This
user guide describes the standard features and functions of AS726x-iSPI evaluation kit.
Please note, the A726x iSPI is a common hardware platform that is equipped with the specifically
requested AS726x device and its corresponding firmware pre-installed in the flash EPROM . The
differing iSPI demo kits utilize common functions and components as described here. A comment in
this manual will be given separately in case of any differences between the singleindividual demo
kits. The following table lists the demo kits the sensor and filter channel characteristics and relevant
channel references detailed in the device data sheet and presented by the graphical user interface.
XYZ = CIE1931 (detector with standard observer function), DK = Dark (detector capped), CL= Clear (detector without filter)

Getting Started
The evaluation kit requires one time installation of FTDI CDM Driver for the USB-MPSSE cable if it is
not already installed on the computer. The installation file can be found in the USB Memory Stick. For
additional assistance on installation of the FTDI driver, please refer to
www.ftdichip.com
for more
information.
The AS726x Spectral Sensing – iSPI software does not require separate installation. Simply copy the
following files to any folder on the host systemand start the .exe file to start the GUI.
