1 INTRODUCTION
Important information: Read the manual carefully before using this device.
Inappropriate utilization may cause damages to the device, to the DUT (device under test) or other components
of your setup.
Please keep these instructions in a safe place and pass them on to any future user.
1.1 Intended Use
The iQ-LED bundle is provided as a component to build your own spectral programmable light source.
1.2 General Safety Information
WARNING!
Some LEDs are emitting invisible light in the IR and UV near area.
•Do not look directly into the emitted light or through the optical LED system.
•Do not look directly into the light source when using high intensities or sequences with low
response time.
•Do not open the device without any instructions from the Image Engineering support team or
when connected to the power supply.
2 GETTING STARTED

2.4 Connection of CAN-USB board / control panel PCB
Connect the small green CAN-USB adapter board via the two red connectors to the backside of the iQ-LED
board (picture flag 2). You can fix the adapter board with a screw to the main board if needed. If you use more
than one iQ-LED in a row, you still need one CAN-USB adapter on the first iQ-LED in the row.
The control panel board (if needed) must be connected to the CAN-USB adapter board via the ribbon connector
cable.
Connected CAN-USB adapter board
Control panel PCB
On the control panel PCB, it is possible to set different light settings for the iQ-LED´s (without a connection to a
PC):
owith the “+” and “-“ buttons you can switch between 44 saved illuminants
onumerical display to show the storage of the illuminants
owith the play and stop button you can start and stop a saved light sequence with different
illuminates (it is possible to save one sequence)
owith the power button, you can turn on and off the light
To create and store illuminants (or sequences) on your device, please follow the instructions in the SW manual.

2.5 Using several iQ-LED elements/dip switch ID’s
The first iQ-LED in a row (or when using just one iQ-LED) must have the ID 1. Set the ID’s of each iQ-LED via
the dip switch (picture flag 3) on the corresponding board. The numbers have to be set in binary mode. It is
recommended to set the ID’s according to the positioning in the row where they are connected via the CAN
connectors (picture flag 4). For example: if four iQ-LED’s in a row are used, set the ID’s to 1,2,3 and 4. On the
last iQ-LED in a row (also in single usage mode) the load resistance dip switch (picture flag 6) number 1 has to
be set to the ‘on’ position, this activates the needed load resistance at the end of a row.
2.6 Power connect
Connect the power cable to all of your iQ-LED’s via the power connector (picture flag 1). You can test if your
device is powered as described in chapter 2.11.
2.7 Connect iQ-LED to your PC
When all iQ-LED’s are correctly connected, and the power is on, you can now connect your PC with the USB
cable to the CAN-USB connector. The first time you attach your iQ-LED to a PC, the iQ-LED driver will be
installed; this may take a few seconds.
2.8 Connect spectrometer to your PC
Connect the USB cable from your spectrometer to your PC. The first time you connect your spectrometer to
a PC, the driver will be installed; this could take a few seconds.

2.9 The arrangement of the iQ-LED and spectrometer
Arrange your iQ-LED devices so that the spectrometer can measure enough light of each iQ-LED and LED
channel. Ensure that the light from all of the LED’s is correctly mixed when measuring with your spectrometer
and illuminating your target / DUT. If it is necessary, use diffusion material or extensions such as the Image
Engineering edgeBox or an integrating sphere to mix the light of all the LED’s.
2.10 Starting software/usage of API
When using the iQ-LED system for the first time, you must set the integration time of your spectrometer to a
corresponding value. This procedure will ensure high performance in low light and will also help avoid any
clipping in the spectral measurement when all iQ-LED’s are set to maximum. Please note that you must also
calibrate your system, please read the SW-control manual and follow the calibration steps.
When using your iQ-LED together with the API, please follow the instructions of the API manual.
2.11 A quick test of functionality without a PC
You easily can test all LED channels of your iQ-LED without using a PC. Just connect the power to your iQ-LED
and press the test button (picture flag 5) on the iQ-LED board. All 20 channels of your iQ-LED (and connected
iQ-LED’s in a row) will light up separated one after the other, click by click. After 20 clicks on the test button, all
LED’s will be turned on. A final click will turn on the fan before turning off all of the LED’s. The intensity of the
LED’s when using the test mode is set to a much less intense level, but it is still advised to not look directly into
the LED’s.

3 ADDITIONAL INFORMATION
3.1 Maintenance
The spectrometer requires a recalibration once a year, regardless of the operating hours. If a spectrometer
calibration is necessary, please contact Image Engineering.
3.2 Care instructions
•Do not touch, scratch or pollute the LED’s
•Do not remove the fiber from the spectrometer, or else the calibration is invalid, and the
spectrometer has to be recalibrated!
3.3 Disposal Instructions
After the service life of the iQ-LED bundle, it must be disposed of properly. Electrical and electromechanical
components are included. Observe your national regulations and make sure that third parties can not use the iQ-
LED after disposal.
Contact Image Engineering if assistance for disposal is required.
