Safety Precautions
Read this section before using the LSS-2404. Always observe the following safety precautions. If in doubt,
contact CCS America, Inc. The following symbols are used in this guide:
Warning: Read the instructions to understand the possible hazards.
Warning: Surface may get hot.
Warning: Possible hazardous voltage.
Refer to the text in this section for precautions you should take whenever the above symbols appear in this
guide.
Heat
Ensure that the LSS-2404 is mounted correctly (see Mounting the LSS-2404),
and that you do not exceed any of the ratings for the unit (see Specifications
and Ratings).
At its maximum ratings, the LSS-2404’s enclosure cannot exceed 50 °C,
which is sufficient to cause a burn if touched.
Place the unit in a position where personnel cannot accidentally touch it and
ensure there is a free flow of air around the unit.
Electrical
The LSS-2404 produces high energy pulses.
Take care to connect the outputs correctly and protect the output wiring and
load from any short-circuits.
When switched off, energy may remain stored in the 2404 for a few seconds.
Use caution with connections immediately after shut down.
The 2404 does not have complete tracking isolation of input and output.
Transients caused by inductive loads must be suppressed externally to the 2404.
The LSS-2404 is a Class B device intended for industrial or commercial
applications, even though it does conform within Class A emission limits which
are stricter for residential use. If any unwanted interference does occur, cable
shielding, grounding, and the product installation should be reviewed by the
user to restrict emissions to a level that prevents interference with broadcast
transmissions.
General
The LSS-2404 must not be used in an application where its failure could be a danger
to personal health or damage to other equipment.

LSS Overview
Terminology
Recipe Settings
Fixed settings for each recipe that do not vary across the frames or sequences (to be defined later). These are
considered global parameters that are set once in the recipe. Trigger Type, trigger event, trigger level, trigger
delay, output trigger delay, ground trigger, camera trigger voltage, and camera trigger width make up recipe
settings.
Active Settings
Settings the LSS are currently running which are loaded into RAM. Active settings reside in volatile memory and
will not be saved when power is lost unless stored to flash memory.
Saved Settings
Settings in persistent storage, either onboard flash memory or PC files. Active settings can become Saved
settings when using the Save to Controller or Save to File commands.
Sequence Settings
Settings that are defined within each sequence thus can vary between different sequences. Executions, number
of frames, and channel mapping are considered Sequence settings
Frame Settings
In most cases, these settings apply across all frames in a sequence. However, an Advanced Mode allows you to
set different strobe widths from frame to frame within a sequence. Frame time, strobe width, frame rate,
independent strobe widths, and independent widths make up the Frame Settings.
Frames
Every frame is an image the camera captures with the programmed lighting channels. Multiple frames are
combined to create sequences and multiple sequences can be linked to create a recipe. There is a maximum of
12 frames per sequence.
Channels
Channels refer to output channels for attached lighting. Lights attached to the LSS may either be segmented
lights or independent lights. Dedicated computational imaging lights, such as the HPR2-150SW2-DV04, have pre-
wired segments connected to each channel. When using a breakout cable connected to any individual CCS lights,
the user will connect each light to a channel. Checking the corresponding Channel box within a Frame turns that
segment or connected light on for the set exposure time for that Frame.
Sequences
The number of frames and their settings make up one sequence. When a sequence is completed the camera
software is able to complete one output image. There can be 10 different programmed sequences on the LSS
controller, but each sequence can be programmed to execute multiple times.

Recipe
Recipes are made up of multiple sequences. There can only be 6 defined recipes on the LSS controller. Each
recipe has its own recipe settings.
Trigger
Typically, triggers are sent directly to a smart camera and light simultaneously; using the LSS, the trigger is sent
to the LSS controller. The LSS controller then sends outputs to the camera and light at the programmed
intervals. Timing Diagrams are available in Appendix C.
Raw Images
Images that are captured based on the settings of each frame. They are then compiled together in the camera
software to create enhanced output images, sometimes referred to as “super images” because of their unique
characteristics; e.g. photometric stereo (PMS) images.
Output Images
Images resulting from combining raw frame images into one final image. In the case of PMS, the 4 raw images
create two output images; one shape image and one texture image.
Principle of Operation
The LSS-2404 is a programmable device that can be used to create multiple types of images. It is configured
from a standard web browser and can store and execute arbitrarily complex lighting sequences for multi-shot
imaging. The architecture is flexible and consists of recipes, sequences, and frames. Each frame corresponds to
one captured image and synchronous strobe output (light flash). Multiple frames together form a sequence and
each sequence results in an inspection image (output image). This output image can result from multiple images
merged via a computational imaging technique, or an image achieved with traditional lighting. Frames can have
their own settings per sequence. In addition, sequences can be set to repeat multiple times and every sequence
in a recipe can have different settings.
Multiple sequences combine to form a recipe. The recipe is the highest level of organization and can be thought
of as the instructions for creating a set of multi-shot and/or conventional images. Each recipe can have its own
global settings. The LSS-2404 can store up to 6 recipes in flash memory, but additional recipes can be created
and saved to the PC and loaded into the LSS-2404 when necessary.
When the LSS-2404 controller is powered up the last saved settings are loaded from internal flash memory. A
different recipe (i.e. configuration) can be uploaded from the PC via the LSS-2404 software if desired.

5 | P a g e
The image below illustrates the LSS-2404 architecture with relation to the settings.
Once a trigger activates the LSS-2404 controller, it begins to run the programmed recipe. The recipe can have up
to 10 different programmed sequences. Within one sequence, you determine how many frames to take and
which lights or light segments will turn on for each frame. Multiple lighting patterns are made by enabling
different channels within each frame −this is also known as channel mapping. Every sequence creates one type
of image for the camera software.
Once the channel mapping of a sequence has been determined, choose the number of times the sequence
executes. Once the LSS-2404 is triggered it will run the sequence through for the specified number of times
before moving onto the next sequence. For example, setting a PMS sequence to execute 2 times will give the
camera software 8 raw images and therefore make 2 sets of output images (2 shape images plus 2 texture
images).
