Page 5: Introduction
Introduction Getting Started This user manual describes the set up and basic operation of the LSS-2404 lighting controller, as well as the corresponding configuration software. Before using it, please read the manual carefully to ensure proper use. After reading the manual keep it in an easily accessible location for future reference.
Page 6: Safety Precautions
LSS-2404 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.
Page 7: Lss Overview
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.
Page 8: Principle Of Operation
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.
Page 9 Frame Settings Frame 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 −...
Page 10: Hardware Information
This information is for guidance only. Installers must perform their own risk assessment specific to each installation. While CCS America Inc. has taken extensive care in the preparations of this advice, CCS America Inc. accepts no liability for damages of any kind except those required by law. Deliberate acts of endangerment and vandalism are not covered by this document and must be considered by the installer.
Page 11 LSS-2404 Mounting the LSS The LSS is intended to be mounted to a standard DIN rail. Hook the top of the DIN rail mounting groove over the rail, pull the spring loaded, red DIN rail lock to guide the bottom of the DIN rail mounting groove fully onto the DIN rail, and release the lock.

Page 14: Connection Requirements
In the event of a fault condition, remove power and the fault condition (if applicable) and wait five minutes. Power the LSS-2404 back on to restore operation. The product warranty does not cover any damage that may have occurred due to improper connection or operation.
Page 15: Selecting Power Supply
DO NOT USE THIS DEVICE WITH POWER SUPPLIES OR EXTERNAL COMPONENTS USING AN ISOLATED GROUND SYSTEM THAT CANNOT BE CONNECTED TO AC GROUND. EXTERNAL COMPONENTS MUST SUPPORT A COMMON GROUND SYSTEM. To request configuration for use in floating or isolated ground systems, please contact CCS America by sending an email to techsupport@ccsamerica.com Ethernet Connection Ethernet connectivity with TCP/IP protocol is standard on the 2404 controllers.
Page 16: Trigger Input
Trigger signals must be clean and sharp at the 4.7K ohm input termination to the LSS-2404. Be sure the trigger device supplying the signal and cabling are appropriate to drive the termination. Do not exceed 30 V absolute maximum at any time or damage may occur to the input.
Page 17: Trigger Output
Voltage Mode The trigger out signal from the LSS-2404 is a voltage driven source. Connect it directly to the receiving device’s input with the polarity shown. Be sure that the input device can accept the ground referenced input. The signal level is software selectable to 5, 12, or 24 V and can drive up to 70 mA.
Page 18: Lighting Output
For the LSS-2404, an M12-5 connector must be used. The M12-5 lighting output connector directly connects to the CCS HPR2-XXX-DV04 ring light (XXX is the size of the ring light), or a 4 bar light configuration using a breakout cable. Please make sure you have the correct cables to connect your light to the LSS controller.
Page 19: Ethernet
(preferred method). If using a POE camera, do not connect the LSS controller to a POE powered port. The LSS-2404 IS NOT a POE device. Connection of the LSS-2404 to a POE port is a safety and fire hazard; damage to the LSS-2404 may occur.
Page 20: Mounting
The channel order for the LSS-2404 with a camera is counterclockwise. The camera must always be mounted in the center of the light arrangement, but the rotation of the light is dependent on software. Check with the image merging software developer to determine what the orientation of the camera and light should be, if applicable.

Since default trigger type = one-shot, it waits for trigger before executing. Note: This will change the recipe settings but not the IP address Test (2) Used to transfer current GUI settings into RAM, i.e.
Page 29: Recipe Settings
LSS-2404 Recipe Settings Trigger Type (16) Triggered One-shot (default) – Executes one triggered recipe per rising edge on the Trigger In signal, regardless of the signal’s length. The signal must return to the low state before the LSS can be triggered again.
Page 30: Sequence Settings
Number of Frames (30) Sets the number of frames in the programmed sequence; maximum 12 frames. For the LSS-2404, the default is 4 frames to correspond with flashing each of the 4 segments one time for the photometric stereo technique (PMS).
Page 31 LSS-2404 Independent Widths (27) Check the ‘Independent Widths’ box to enable the ability to set a different time for each individual channel. When unchecked the Strobe Widths for all 4 channels will be locked to each other; changing one changes them all.

Page 33: Motion Correction
LSS-2404 The timing diagram below illustrates the definitions described above in relation to the timing of the system. More timing diagrams for triggering are shown in Appendix D. Motion Correction If the part is in motion during the multiple image capture sequence, a compensation technique called motion correction is needed.
Page 34: Troubleshoot
To manually turn on a segment of the light open another browser tab → in the browser type (IP address LSS is set to) 192.168.0.10/chX=1 to turn on and 192.108.0.10/chX=0 to turn it off. Where X represents the number of the channel being forced on. X can be 1,2,3, or 4 for the LSS-2404. Ethernet connection If an ethernet connection is lost, refresh the browser webpage.

Erases all the stored recipes and loads in default settings except for serial number, MAC address, authentication string, static IP address, and DHCP flag. The reset button is located next to the ethernet connection on the inside of the LSS controller to prevent accidental resets.

Appendix A. LSS-2404 Specifications LSS-2404 Specifications The LSS-2404 Light Sequencing Switch is designed to switch external +24 VDC power for up to 4-channels of lights. Upon receiving an external system trigger, Description the LSS-2404 executes a preprogrammed sequence of lighting on the 4-channels and outputs a correlated camera trigger, automatically timing external camera exposures to the programmed lighting sequence.

Page 40: Timing Diagrams For Triggering
LSS-2404 C. Timing Diagrams for Triggering Trigger Type: One Shot (Default) Trigger Event: Series When a trigger is sent in, the first recipe runs until completion then waits until it receives another trigger to trigger the recipe again. When a recipe is triggered it runs all sequences; the frames within a sequence and the number of times a sequence is programmed to execute.
Page 41 LSS-2404 Trigger Event: Sequence Every trigger that comes in triggers the next sequence in the recipe. When a sequence is triggered it runs through all programmed frames then stops and waits for another trigger to start the next sequence. If the sequence is programmed to execute multiple times; one trigger will run all the executions for that sequence.
Page 42 LSS-2404 Trigger Event: Frame Every trigger that comes in triggers the next frame in the sequence. The first trigger enables the recipe, first sequence, and first frame. The next trigger triggers the second frame in the same sequence and so on until all the frames have been triggered.
Page 43 LSS-2404 Trigger Type: Continuous Recipe runs in a loop as long as the trigger signal remains high. When the trigger signal drops the LSS finishes the recipe that has started and ends. Trigger Type: Free-Run Recipe runs in a loop as long as the free-run trigger type is enabled. It does not require a trigger to begin running the sequence.
