1 Introduction
1.1 The Lumenera USB and GigE Camera Family
Lumenera cameras provide a quick and easy means of displaying and capturing high quality video preview and images
on any USB 2.0, USB 3.0 or GigE-equipped desktop, laptop or embedded computer.
Designed with flexibility in mind, each camera model has its own distinct characteristics and performance advantages,
whether speed, resolution, image quality, sensitivity or price. Because they are USB and GigE-based, there is no need
for a framegrabber. Instead, a single cable provides full command control and data transfer at speeds of up to 24 MB/s
(Lu series), 48 MB/s (Lw series), 500 MB/s (Lt series) or 100 MB/s (Lg series).
Most cameras have a provision to be externally powered for cases where the USB port does not supply sufficient power
(e.g. some USB cards on laptop computers). GigE products and large format cameras require an external power supply.
All cameras share the same simple, yet powerful API allowing easy migration from one camera model to another. Both
board-level and enclosed cameras are available. All cameras also have an external interface header for hardware input
and output signals.

2 Installing and Using the Camera
2.2 Camera and Software Installation
The Lumenera camera you have just purchased is designed to operate with minimal setup.
Note: Prior to plugging the camera into the computer, you must first install the software. In the event that the
camera was connected to the computer prior to the software being installed, it will be necessary to perform some
manual setup using the Windows Device Manager following the software install. Refer to the trouble-shooting section
2.2.8 of this manual for the necessary instructions.
2.2.1 Minimum System Requirements
Windows 7 or Windows 8.1 or Windows 10
32 and 64-bit platforms are supported
1.0 GHz Pentium III or higher (compatible)
512 MB RAM (1 GB recommended)
USB 2.0, USB 3.0 or GigE port.
2.2.2 Camera Power Requirements
Most camera models run directly off the USB bus for power supply, command control, and data output. In some cases
and/or camera models, there may be a need to externally power the camera. Large format cameras (Lw1105x,
Lw1605x), some USB 3.0 cameras (Lt365, Lt665, Lt965, Lt1265) and GigE cameras run off the external power supply
only. Please refer to Section 3.7 for more information on selecting the appropriate power supply for your camera. If an
incorrect external power supply is used, it could damage the camera and void your warranty.
The Lt225 & Lt425 camera models operate using power directly taken from the USB 3.0 ports. In some circumstances it
may be desirable or necessary to provide external power to operate these camera models. Also, if the Lt225 or Lt425
camera models are used on a USB 2.0 port, they will require a 5V, 1A DC external power supply provided through the
GPIO connector. Refer to section 3.6.5 for specifications and pin-out to apply external power to the USB 3.0 camera
model.
For Lt365, Lt665, Lt965 and Lt1265 there is an optional way to provide power to the camera by using a Y-cable. Please
consult Annexe-1 for more information.
2.2.3 Camera LED indicator
The Lumenera Lu and Lw cameras models include a single function LED that illuminates once the camera device
drivers have successfully loaded and the camera is operational. The LED is an amber color for the Lu series and a
green color for the Lw series camera models. If the LED fails to illuminate on an Lu or Lw camera model, this typically
indicates that the Windows operating system has not successfully loaded the device drivers onto the camera.
For the Lumenera Lt camera models, a multi-function LED that illuminates in either green or orange to provide additional
information that can be interpreted by the camera operator. If the indicated status is not easily understood, then contact
the Lumenera Support team with a description of the LED behaviour. Check the Table 1 or Table 2 below for the LED
appearance and typical meaning.

2.2.6 USB Plug-and-Play Device Recognition
Windows 7, Windows 8 & Windows 10Systems:
The Lumenera USB camera drivers are digitally signed with Microsoft. Under Windows 7 operating systems the camera
will be automatically identified, and the drivers will be silently loaded in the background. Typically a small balloon dialog
appears in the lower right hand side of the screen indicating that a device has been detected and the drivers are
loading. Allow up to 1 minute for the device drivers to load, and when the LED is illuminated on the camera it is
operational.
Run the LuCam Capture application software from your Start menu to control the camera.
2.2.7 Software Upgrade Procedure
The Software Upgrade procedure is similar to the original software installation. If you have installed a previous version of
the software you should uninstall it prior to running the Software Upgrade.
Note: Should the Uninstall Script identify that a reboot is required, please ensure that you perform this step by
rebooting your computer before installing the Software Upgrade. Failure to do so could cause difficulties with any future
installations.
If you run the Software Upgrade without uninstalling the older version, it will uninstall it for you. The Software Upgrade
procedure will launch automatically to install the new software, immediately following the un-install.
USB 3.0 and GigE camera model may require a product firmware upgrade. The software to upgrade product firmware
could be downloaded at http://www.lumenera.com/support/downloads/industrial-downloads.php. The installation
instruction will be included in the package and it is highly suggested that you review these instructions prior to proceed
to a product update.
2.2.8 USB Camera Troubleshooting
In the event that the Lumenera USB camera is not functional, the most likely reason is that the drivers were not loaded
to the camera. This can occur when a camera was connected to the PC prior to the software being installed. When the
USB plug-and-play device detection is initiated for any new device, the operating system will effectively quarantine the
device if it cannot locate the appropriate driver files. In this event, the camera drivers will be blocked from loading even
after the drivers are installed, unless the device detection process is invoked manually. The steps to correct this only
take a couple of minutes to complete.
Make sure that the Lucam software is installed before proceeding.
1) Right mouse click the “My Computer” icon on your computer screen and choose “Properties”. Click “Device
Manager” on System Properties window.
A keyboard shortcut exists to access this menu quickly, press the “Windows / Start” key and the “Pause / Break”

2.4 Using the Installed Software
All of the necessary software and device drivers are contained in an installation program available on the Lumenera
website under the Support section.
The following files are installed when you run the installation program:
2.4.1 Drivers & INF
The Lumenera camera driver files come as a pair for each camera model, supporting a two-stage driver load process.
These two files have the .sys extension and are copied to …\SYSTEM32\DRIVERS folder in the standard Windows
folder on your system. These files are named LucamXXX.sys and LuldrXXX.sys or LwcamXXX.sys and LwldrXXX.sys,
ltcamusb.sys or LccamXXX and Lcldr (the XXX represents the 3 digit camera ID number).
Each of the .sys files is called into operation by a custom file with the .inf extension The location of the inf files is
controlled by the Windows O/S. They are installed and copied to the …\INF folder in the standard Windows folder on
your system. There are up to two of these files for each camera model supported by the software. The names of these
files are LucamXXX.inf and LuldrXXX.inf or LwcamXXX.inf and LwldrXXX.inf (the XXX represents the 3 digit camera ID
number). USB 3.0 cameras are all using the same driver ltcamusb.inf.
Lumenera uses a custom utility to ensure that the driver files are installed and registered to conform to Windows logo
testing. The application is called luihlp.exe and is included with the driver-only installation packages described below.
2.4.2 DirectShow Filters
Several DirectShow (or WDM) related files are installed in the …\SYSTEM folder in the standard Windows folder on your
system. All of these files have the .ax extension. These files are stored in the program files folder where the Lumenera
software is installed under:

evaluation of the camera functionality and performance. By default these applications are installed to C:\Program
File\Lumenera Corporation\LuCam Capture Software\Executables directory for 32 bit Windows systems. For 64 bit
Windows systems, the executables will be installed in the C:\Program Files (x86)\Lumenera Corporation\LuCam Capture
Software\Executables directory. The majority of the LuCam API functions are exercised in these sample executables.
Support for these sample programs is not provided. Although they are periodically maintained some of the samples do
not function with every Lumenera camera model.
2.4.5 Software Development Kit (SDK)
The software development kit is required for software development with Lumenera camera models. In order to minimize
customer development cycle, Lumenera is providing one SDK that is shared by our USB2.0, USB3.0, GigE and

Included with the SDK are Driver Only installation packages that can be used to install and run the specific camera
models on any computer without the need to install the complete software package. In each camera model directory you
will find the camera driver and .inf files, the DirectShow files and the API DLL files. Also included in the directory, there is
an installation batch file that can be used to install these files or used as a reference for your own installation script and
the Microsoft regsvr32.exe application needed to register the Lutf.ax DirectShow filter file. These packages are installed
in a folder called “Driver Only Installations” in the directory selected during the installation process. The default location
is:
C:\Program Files\Lumenera Corporation\Lumenera Camera SDK\Redist (32 bit Windows)
C:\Program Files(x86)\Lumenera Corporation\ Lumenera Camera SDK\Redist (64 bit Windows)
The files contained in these directories are the same ones used by the camera. If, during your development, a camera
file update is required, use the updated files as part of your installation package. You can replace the files in this
directory as necessary.
Note: LgCam Software installation does not have a driver only installation package, therefore the complete installation
process is required to ensure all dependencies are installed.

2.5 Using LuCam & LgCam Capture
The LuCam and LgCam Capture applications are simple demonstration programs that are easy to use. The applications
are built using the SDK and are a sampling of what the API functions can do; however, it does not incorporate all of the
available features of the API.
Only one camera may be controlled by each instance of LuCam (LgCam) Capture, but several instances of the
application may be run simultaneously. If more than one camera is detected by the application, a list of available camera
serial numbers is presented allowing the user to select the camera they wish to control.
Additionally, the image stream from any one camera can only be provided to a single application. If LuCam (LgCam)
Capture or any one of the sample executables is extracting a video stream from the connected camera, it must be
stopped before another application will be able to access it.
Launch the LuCam (LgCam) Capture application from the Windows Start menu or from a desktop shortcut icon.

The video frame Capture button is used to grab a frame of video from the video stream and display it on screen.
The Save As button is used to save the image to disk in one of the available formats.
The Hide Capture button will close the image display window.
The Capture & Save Bayer Data toggle button allows you to view and save the raw Bayer data that comes from the
camera, before it is processed into 24-bit RGB data (color cameras only). If a captured image is currently being
displayed, this button will toggle the image between raw Bayer and processed 24-bit data.
2.5.2 Dialog Items
Video Image Control
The Image Size dropdown list provides the available video display resolutions. The Preview must be stopped in order to
switch between the various image sizes.
The Frame Rate dropdown box provides a list of available display frame rates. Not all cameras have this capability.
The Taps dropdown box provides a list of number of taps available to select. Not all cameras support multiple taps.
The Exposure text box or slider is used to adjust the video exposure time in milliseconds.
The AEC toggle button is used to toggle the Automatic Exposure Control (not available for all cameras). When selected,
the slider changes to Luminance Target allowing you to select the average brightness you want to maintain as ambient
lighting changes. The exposure will be automatically adjusted in an attempt to maintain the average brightness.
The Gain text box or slider is used to adjust the global gain of the camera for both video mode and when using the
Snapshot mode (described below). The gain value is a multiplicative factor, so a value of 1 means no gain. The value of
every pixel in the image is multiplied by the gain value, resulting in an increase in image brightness. When the gain
setting is increased, any sensor noise will be amplified, along with the image data, and the picture quality will be
degraded. The higher the gain, the more noticeable this is.
The AGC toggle button is used to toggle the Automatic Gain Control (not available for all cameras). When selected, the
slider changes to Luminance Target allowing you to select the average scene brightness that you want to maintain as
ambient lighting changes. The gain will be automatically adjusted in an attempt to maintain the average brightness.
Note: When both AEC and AGC are selected, if an increase in brightness is required, exposure is amplified first until its
limit is reached and then gain is adjusted. When a decrease in brightness is required, gain is reduced first until its limit is
reached and then exposure is adjusted. This maintains the best image quality.
The Gamma value is applied to the image to make it look better on screen. It is used to correct the non-linearity
inherent in most CRT monitors. A value of 1 represents no gamma correction. Values less than one will make the image
appear darker while a value greater than one will make the image appear brighter. For more information about Gamma
and why it is used consult: www.poynton.com/GammaFAQ.html.
The WBbutton adjusts a camera’s video preview color gain settings (white balance), based on the overall image, using
the Gray World Algorithm. It is done in software by grabbing a video frame, analyzing it, adjusting the color gains and
repeating, until the colors in the image are balanced (resulting in an equal amount of Red, Blue and Green in the image).
It is best to put a neutral target (e.g. white or grey paper) in front of the camera before performing a color balance. For
best results, the image exposure time should be adjusted so that the scene does not contain any saturated pixels
(values at maximum brightness).
The AWB toggle button is used to enable or disable continuous white balance. If enabled, the camera will automatically
adjust white balance on each video frames received.

3 Understanding Your Camera
3.1 Shutter Types and Scanning Mode
Depending on the camera model that you have, the following electronic shutter types may or may not be present. Check
Table 3, at the end of this section, to determine the shutter type associated with each camera model. These types are
selectable for the snapshot mode of the camera (described in a later section).
3.1.1 Rolling Shutter
With a rolling shutter the exposure process begins, whereby rows of pixels in the image sensor start exposing in
sequence, starting at the top of the image and proceeding row by row down to the bottom. At some later point in time,
the readout process begins, whereby rows of pixels are read out in sequence, starting at the top of the image and
proceeding row by row down to the bottom in exactly the same manner and at the same speed as the exposure process.
The time delay between a row starting to expose and a row being read out is the integration time, also known as the
exposure time. This integration time can be varied from a single line (start exposure followed by a read out while the
next line is exposing) up to a full frame time (last line starts exposing at the bottom of the image before reading starts at
the top). In some cases, longer exposures can be obtained by delaying the read out even longer (during which time, the
entire array is exposing).
Since the integration process moves through the image over some length of time, skewing of moving objects may
become apparent. For example, if a vehicle is moving through the image during capture, light from the top of the vehicle
will be integrated at some earlier time than light from the bottom of the vehicle, causing the bottom of the vehicle to
appear slanted forward in the direction of motion. For most slow moving objects or still image capture, this motion
artefact is not noticeable.
3.1.2 Half Global Shutter
With a half global shutter, the entire image array starts exposing at the same time (globally). At some later point in time,
the readout process begins, whereby rows of pixels are read out in sequence, starting at the top of the image and
proceeding row by row down to the bottom (exactly like the rolling shutter case).
The time between the global start of integration and the start of readout is defined as the exposure time. However, since
during readout of the image the lines are still integrating (like rolling shutter), the actual image exposure differs from the
top to the bottom. The difference is the time taken to readout the image and varies for each camera (70 ms is typical).
Under bright ambient lighting conditions, the image will appear brighter; the further down the image you go. A half-global
shutter is most effective when used under controlled lighting (e.g. strobe flash).
Because integration continues to occur during readout, the skewing motion artefact can still occur.
3.1.3 Global Shutter
With a global shutter, the entire image array starts exposing at the same time (globally). At some later point in time, the
entire image array stops exposing at the same time and the image is read out in sequence, starting at the top of the
image and proceeding row by row down to the bottom (sometimes odd rows are read out first followed by the even
rows). The difference from the other modes is that during readout, the imager is no longer integrating light.
The time delay between the start of exposure and end of exposure is defined as the exposure time and it represents the
total amount of time that the image integrates.
Because all the pixels start exposure at the same time, integrate over the same interval, and stop exposing at the same
time, there is no potential for motion artefacts as there is in the other modes.
In a progressive scan camera, the entire image is integrated (exposed) at one point in time (for global shutters) or lineby-line from top to bottom (for rolling shutters).

3.2 Use of Flash or Strobe
A flash or strobe may be used with any camera model and the option is available to provide a programmable trigger
signal from the camera to the flash or strobe device to tell it when to fire. However, the type of shutter mode being used
will dictate what conditions will be required and how well flash photography will work with the camera.
3.2.1 Flash with Rolling Shutter
The use of a flash with rolling shutter is only feasible for cameras that allow exposures longer than frame read out time
(typically about 70 ms). This is because with exposures less than that, only a band across the imager is being exposed
at the same point in time and when the flash occurs, it will only illuminate that region of the imager. The flash must be
fired at the time when all the pixels of the imager are simultaneously sensitive to light. The strobe signal from the
camera is generated at a user selectable delay from that point in time.
Generally, the ambient lighting should be low enough (i.e. dark) so that during the overall exposure the ambient light will
not contribute much to the overall brightness of the image. This is particularly true if the flash is being used to stop the
motion of a fast-moving object; otherwise, blurring or skewing may occur. For imaging still objects, this is not as much of
a concern. In this case, you only need to ensure that you are not overexposing the object with both a long exposure and
a flash.
3.2.2 Flash with Half Global Shutter
The use of a flash or strobe with an imager using a half global shutter is similar to the rolling shutter case. However,
because the imager starts at once exposing all the pixels globally, the strobe signal from the camera is generated at a
user selectable delay from the start of exposure. It doesn’t have to first wait for the rolling shutter to open up all the way,
like for rolling shutter mode.
Again, the ambient lighting should be low enough so that during the image read out where the imager is still sensitive,
the ambient light will not contribute much to the overall brightness of the image. This is a concern for both moving
objects where both blurring and skewing may occur, and still objects where you may have uneven brightness from the
top of the image to the bottom (as described in the previous section.)
3.2.3 Flash with Global Shutter
The use of a flash or strobe with a global shutter has no limitations or concerns. The strobe signal from the camera is
generated at a user selectable delay from the start of the exposure. Very short, global exposures can be used, so there
will be no blurring or skewing or overexposing due to long exposures.
3.3 Camera Modes
The camera has two operating modes: Streaming Video and Snapshot.
3.3.1 Streaming Video
In streaming video mode, image frames are continuously being sent from the camera to the computer where they are
available for use. The data is pushed from the camera, with no user intervention required. An output signal is provided
on the external I/O header indicating the start of exposure for each video frame and can be used to help synchronize
events with the video images. The camera will operate with the fastest frame rates in this mode.
3.3.2 Snapshot (still mode)
Snapshot mode is used to capture one (or more) individual frames in an asynchronous manner. In this mode, the user
must initiate the action to start the image retrieval through either hardware or software.
The software trigger is provided using API function calls. The function call is made causing the snapshot to be taken and
a single image is returned.

The hardware input trigger with or without programmable delay can be used to initiate the snapshot via the external I/O
interface. An API function call is made that puts the camera into this wait for hardware trigger state and then blocks until
the hardware trigger is received. Once the trigger is received, the API function returns and passes back the image or a
timeout error code if the user selected timeout occurs.
Any of the available shutter types can be used with snapshot mode. An output strobe signal with programmable delay
can also be synchronized with each snapshot. This is described in more detail in External I/O Interface section.
3.4 Data Format
Unlike most commercial cameras (Canon, Nikon, etc.) raw data format that usually proprietary to camera manufacturer,
it contains camera settings and other meta data for post processing in addition to the standard raw image data. The
RAW data from Lumenera camera are actual RAW pixel values. Take an 8-bit 16x16 image as an example shown in
Figure 24: Monochrome pixel mapping, the raw image data are all 256 pixel values saved row by row.
Figure 24: Monochrome pixel mapping
The RAW data has two available pixel formats that represent pixel bit depth, i.e. 8 and 16 bpp (bits per pixel). For
16bpp pixel format, depending on the camera model, 10, 12 or 14-bits will be valid data, with the remaining 6, 4, or 2bits always set to zero.
The pixel data bits are stored most significant bit aligned in each word. The words are in Big Endian byte order for Lu
series cameras (most significant byte is the first of each byte pair), and Little Endian byte order for Lw, Lt and Lg series
camera (least significant byte is first of each byte pair). The following tables illustrate this point where the data for the
first three pixels (completely light-saturated) of an image are represented.
Design, features, and specifications are subject to change without notice
Table 4: Pixel Data Format for 16 bpp (10 valid data bits) for all Lu series cameras
Table 5: Pixel Data Format for 16 bpp (10 valid data bits) for all Lw, Lt and Lg series cameras
For monochrome cameras, each byte (8bpp) or word (16bpp) represents one pixel in the image.
For color cameras, each pixel is covered by one Bayer color filter. An example of an RGGB Bayer filter is shown in
Figure 25. Each 2x2 sub mosaic contains 2 green, 1 blue and 1 red filter. In Figure 25, pixel (0,0) has a red color filter
that filters light in the red wavelength range; pixel(0,1), pixel(16,0) and pixel(16,1) filter light in the green, green and blue
wavelength ranges respectively. In other words, each pixel will represent one of the RGB colors. The raw image data
from a color sensor will have all pixel values corresponds to the intensity of light filtered by the Bayer filter, also referred
as the raw Bayer format. The raw image data is not bitmap data. To get the bitmap data, a conversion is needed.

Figure 25: Color pixel's mapping (RGGB)
List of sensor Bayer format by camera model is in Table 6.
When creating a formatted image, each pixel of a color image is defined by 3 mosaic color channels (RGB). The API
conversion functions will process each pixel in the raw file to build the corresponding RGB pixels of the image, a process
called Demosaicing. The output of Demosaicing is a BMP data and not RGB data. For BMP data, each pixel’s data has
the reverse BGR order (for 32-bit format, which includes an Alpha channel, it will be BGRA) and the top row of the
image will be the bottom row of the BMP data (inverted). At this point you can save image as Bitmap, TIFF or JPG.
When using the LuCam Capture application to preview video from a color camera or save images to disk, conversion of
the data to standard 24-bit RGB data is done by the software automatically.
When using the API (available with the SDK), you have complete control over this conversion process.
Design, features, and specifications are subject to change without notice
Subwindowing, also known as region of interest (ROI), is the ability of the camera to output a smaller image size
(subwindow) than the whole imager array. An imager that supports a maximum resolution of 1280 x 1024 pixels for
example, could output a subwindow of 640 x 480 pixels with the subwindow being positioned nearly anywhere inside the
1280 x 1024. The subwindow is actually a smaller field of view than the maximum resolution available. There are
limitations on the granularity of the subwindow size and on its position within the whole array. The granularity is 8 pixels.
Subsampling, also known as decimation, is the throwing away of every nth pixel or pixel pair in the image in the X and/or
Y directions. For example, an imager with a maximum resolution of 1280 x 1024 could throw away every second pixel in
both the X and Y directions and output an image that is 640 x 512 pixels, yet covers the same field of view of the original
full resolution. Not all cameras support Subsampling. Those that do may support subsample levels of 2, 4 or 8. Some
cameras even allow different Subsampling in the X vs. the Y directions.
Binning is similar to Subsampling, except instead of throwing pixels away, pixel values are combined in some fashion.
They can be either summed (to provide greater sensitivity) or averaged (to reduce noise). The resulting resolution would
be the same as for Subsampling, but the data from every pixel is used. Several cameras support Binning with binning
levels up to 8 by 8.
It is important to note that certain camera models do work in multi-tap configuration to give better speed performance
and this need to be taken in consideration when working with sub window, subsampling or binning mode.

Optically-Isolated Input
These input pins are designed for 3.3 to 5 V nominal input (12 V absolute maximum). Greater input voltages are
supported with use of external resistor. Current flowing between pins 6 and 3 must not exceed 50 mA maximum, and
should nominally be 20 mA. The internal resistor value on these pins is 220Ω.
Therefore, Vinput = (0.02 A)*(220 Ω + Rexternal)
Optically-Isolated Output
These outputs require an external resistor and current biasing for use. Connect pin 2 to a supply voltage, and place a
resistor between pin 1 and Ground. Measure the current output at pin 1. The current flowing between pins 2 and 1 must
not exceed 50 mA, and should nominally be 20 mA.
For example, if biasing with a 5 V supply (output referenced to 5 V), use a 220Ω series resistor. For a 12 V supply, use
560Ω.
Bi-directional Input/Outputs
The direction of these inputs can be controlled through software. The input pins are 3.3 V or 5 V nominal. The output

3.6.5.1 Recommended Mating Connectors
The HR1824-ND connector can be used as mating connectors MXR-8PIN.
All of these connectors can be purchased from Digi-Key® (www.digikey.com) but other parts suppliers may also carry
them.
There is 2 optional connectors that you can get from Lumenera, the first one is La2000PK which is a 5V power adapter
and the din to HR1824-ND adapter for external power usage. The second optional connector is the La2000PIOK, which
are the combination of a 5V power adapter and the din to Hirose connector with loose wire for easy access to the GPIO
signals. Please refer to section 3.6.5.5 for more information on color coding used to expose IO’s.
3.6.5.2 GPI/O Connector Description
For all GPO pins, the voltage swing is as follows:
For a LOW value: 0.0 to 0.6 V
For a HIGH value: 2.65 to 3.3 V
The typical output current is 24mA.
For all GPI pins, the tolerated input voltage swing is as follows:
For LOW input voltages: 0.0 to 0.8 V
For HIGH input voltages: 2.0 to 5.0 V
3.6.5.3 Optically-Isolated Input
The optically-isolated input pins are designed to operate from 3.3V to 24V at a typical current of 20mA and must not
exceed 50mA. Greater input voltages are supported with use of an external resistor. When current flow from GPI1+ to
GPI1- it will be seen as a level 1 from camera otherwise camera will see it at level 0. A simple usage is to apply the
signal (active high) on GPI1+ and then have GPI1- connect to ground plane of the input signal (Figure 32). In some
applications the trigger may need to be active low, and then Vcc (3.3-24V) from trigger circuit should be applied at
GPI1+ and signal at GPI- as illustrated in Figure 35. The internal resistor value on these pins is 820Ω. Therefore, Vinput
= (0.02 A)*(820Ω + R
external
).
Design, features, and specifications are subject to change without notice
The optically-isolated output requires an external resistor and biasing current. The current flow between collector and
emitter should nominally be 20mA and must not exceed 50 mA. For example, for biasing with a 5V supply (output
referenced to 5V), use a 220Ω series resistor. For a 12V supply, use 560Ω. There are 2 common configuration can be
used for outputs, active high or active low output signal. Active high output, will produce and output level to VCC when
the LED in the opto-coupler is on (Figure 34). Figure 35 demonstrate how to configure the GPO1 to output 0 when signal
is active.
The external GPIO connector can be found on the back of the camera near the LED (up-right).
3.6.6.1 Recommended Mating Connectors
The HR10A-10R-12S(71)connector can be used as mating connectors to Hirose HR10A-10R-12PB (71).
All of these connectors can be purchased from Digi-Key® (www.digikey.com) but other parts suppliers may also carry
them.
There is an optional dongle that you can get from Lumenera, the first one is La3000PAFL which is the combination of a
12V power adapter and the din to Hirose connector with loose wire for easy access to the GPIO signals. Please refer to

3.6.9 Signal Definitions for All Cameras
GPO1 / Strobe Out: This signal serves double duty and is also used to provide an ACTIVE LOW, 5.5 ms pulse (suitable
for triggering a strobe unit) when any of the Take Snapshot API functions are used with the useStrobe option enabled.
This strobe pulse can be delayed with respect to the start of frame exposure by a user selectable amount (see the
Lumenera API Reference Manual for further details). This signal can be toggled using the LucamGpioWrite() function.
For USB 3.0 product the strobe signal can be programme to be used on GPIO2 or GPIO3.
GPO2 / Strobe Out: This signal serves double duty and is also used to provide an ACTIVE HIGH, 5.5 ms pulse
(suitable for triggering a strobe unit) when any of the Take Snapshot API functions are used with the useStrobe option
enabled. This strobe pulse can be delayed with respect to the start of frame exposure by a user selectable amount (see
the Lumenera API Reference Manual for further details). The strobe signal can be toggled using the LucamGpioWrite()
function. For USB 3.0 product the strobe signal can be programmed to be used on GPIO2 or GPIO3. When GPO2 is
programmed to be used as a strobe signal, it simply inverts the polarity of GPO1, so this means that the GPO1 needs to
be programmed as a strobe signal in order to generate the second strobe signal.
GPO3: This signal can be toggled using the LucamGpioWrite() function. If there is no GPO4 or GPIO4, this IO can also
be used as the start of frame signal (SOF).
GPO4 / Video SOF*: This signal serves double duty and is also used to provide an ACTIVE HIGH, 85 μs pulse each
time a frame is output in video mode for most of the cameras. For some of the CCD based cameras*, the duration of the
pulse reflects the exposure set in the camera and the falling edge represents the Start of Readout of the sensor. The
LucamGpoSelect() API function is used to enable/disable the Video SOF signal.
This signal can be toggled using the LucamGpioWrite() function.
* Currently supported on the Lw070, Lw130, Lw160 and Lw230-based cameras.
* This functionality is reported on GPIO3 of GPO3 when this IO is not available.
To enable the feature use the existing API:
LucamGpioConfigure(hCamera, 0x08); // Setup GPIO4 as output
LucamGpoSelect(hCamera, 0); // Disable GPIO on GPO4
GPI1 / Trigger In: This signal serves double duty and is also used to receive an ACTIVE HIGH, LVTTL input (Vin min =
0 V, Vin max = 3.3 V) pulse which will trigger the taking of a snapshot, when any of the Take Snapshot API functions are
used with the useHwTrigger option enabled. The active high pulse must have a minimum width of 0.5 μs. There is no

maximum limit to the trigger pulse width. This signal is floating and MUST be driven at all times when being used. The
signal status can be obtained by using the LucamGpioRead() function.
GPI2: This signal is floating and MUST be driven at all times when being used. The signal status can be obtained by
using the LucamGpioRead()function.
GPI3: This signal is floating and MUST be driven at all times when being used. The signal status can be obtained by
using the LucamGpioRead() function.
GPI4: This signal is floating and MUST be driven at all times when being used. The signal status can be obtained by
using the LucamGpioRead() function.
VCC Output: This optional feature allows the camera to output a 3.3 V DC signal on Pin 16. The camera can source up
to 50 mA of current from this pin. This feature is only available on Lw-based cameras that have been ordered with this
option available. This feature is not available on existing Lu-based cameras. The large format cameras, mini cameras
and GigE Vision cameras do not have this signal available on the external I/O connector.
GPIO2: Ready Signal
The ready signal is an output signal that is raised when camera is ready to accept trigger. This signal only has meaning
when using camera with hardware trigger, however it will still produce when using camera in software trigger. The
signal will be available on GPIO2, so GPIO2 pin need to be configure as an output. In order for the signal to work, the
trigger polarity need to be set so trigger are intercepted on rising edge. This signal does not interfere with the SOF
signal, so it is possible to have the Ready signal and the SOF signal at the same time.
The signal is supported by listed product:
Lt345, Lt545, Lt945, Lt1245, Lt365, Lt665, Lt965, Lt1265, Lt16059, Lt29059, Lt425
To enable the feature use the existing API:
LucamGpioConfigure(hCamera, 0x02); // Setup GPO2 as output
LucamGpoSelect(hCamera, 0); // Disable GPIO on GPO2
3.6.10 Taking a Single-Frame Snapshot with the Camera External I/O Interface
The Lumenera LuCam API makes use of several of the External Interface Header pins automatically; when the Take
Snapshot related functions (those that use the LUCAM_SNAPSHOT structure) are called with certain options (see the
LuCam API documentation for more details). The LUCAM_SNAPSHOT structure allows the setting of the following
parameters that control the taking of a snapshot and the timing of triggers:
Trigger Mode (useHwTrigger): There are two types of snapshot triggering, hardware and software. When enabled, the
snapshot will be triggered when the trigger input signal is detected after a Take Snapshot API is called (the API blocks
until it times out or until the trigger occurs and the frame of data is returned). When disabled, the API function itself
triggers the snapshot and returns the frame of data. The hardware trigger is expected on Pin 9 of the External Interface
Header as described above. The software trigger is initiated from within the API Take Snapshot functions (for more
details see the API documentation.)
Trigger Delay (exposureDelay): A delay in milliseconds from the trigger (hardware or software) to the start of frame
exposure can be set.
Strobe Mode (useStrobe): In concert with either triggering mode, a user may also trigger an external strobe light
synchronized to the frame exposure. When this parameter is enabled, the strobe signal pulse will be initiated on Pins 1
and 3 as described above. In this case, a strobe delay should be defined.
Strobe Delay (strobeDelay): A delay in milliseconds from the trigger (hardware or software) to the strobe pulse (rising
edge for ACTIVE HIGH, falling edge for ACTIVE LOW) can be set.
Exposure Time (exposure): The length of time in milliseconds to expose the image before readout begins.

3.7 External Power
Most camera models are powered exclusively via the USB cable, which nominally supplies 5 Volts. Large format camera
models (eg: Lw11059, Lw16059) require an external 12V power adapter. A power adapter can also be used to power
the camera, in cases where the USB cable does not supply power (e.g. from a Laptop computer or non-powered USB
hub.)
The GigE Vision camera models require an external 12V power adapter at all time.
The appropriate external power adapter for your camera can be purchased directly from Lumenera. The Lumenera
power adapter part number for your camera can be found in camera datasheet on the Lumenera website
(www.lumenera.com) Product tools, in the universal power guide
(http://www.lumenera.com/media/wysiwyg/support/pdf/PowerSuppliesPMN.pdf)
or you can contact Lumenera Technical Assistance team ([email protected]). The usage of a universal power
adapter is also possible and this component must adhere to the following specifications:
Lu series cameras:
1. 6 Volts DC Regulated
2. 1000mA Minimum Current rating
3. 2.1mm Tip
4. Center Positive (+)
Lw series cameras:
1. 5 Volts DC Regulated
2. 500mA Minimum Current Rating
3. 2.1mm Tip
4. Center Positive (+)
Exception: Lw110 uses a 6 V DC power adapter when
USB power is insufficient.

3. Refer to section 3.6.5 for the mating GPIO
connector and pin-out to supply external power
Each camera has a unique camera ID that can be accessed through the LuCam API interface. This ID can be useful to
set specific camera functions in your software. The LuCam Capture application displays this ID in its “About” dialog box.

Lt365R, Lt665R, Lt965R, Lt1265
Cameras
The latest revision of the Lt365/665/965/Lt1265 cameras support full power over USB at any frame rate using a USB 3.0 Y
cable and enabling High Power USB Mode via software. The USB 3.0 Y cable can be purchased separately.
Note: According to the USB 3.0 specification, a certified host port can provide 900mA of power. The Ltx65R cameras can
draw up to 1200 mA when operating at the faster frame rates (in 1, 2 or 4 tap modes). If you plan to use the camera at a
slower frame rate, you can use a standard USB 3.0 cable for power and the entire system will be USB 3.0 compliant. To
remove the requirement for a separate power supply to simplify OEM integration or specific deployments, the cameras can
receive the full power draw over a USB Ycable connected to a host computer’s USB 3.0 port (data and power) and a USB
3.0 port (power only) on the same USB card/controller. The camera needs to have High Power USB Mode enabled which
will allow the camera to draw power from the USB Y cable to operate at the faster frame rates.
To enable the High Power USB Mode, please use the USBPowerMode.exe application distributed with the Lucam
Software package (Path: ..\Lumenera Corporation\LuCam Capture Software\Executables). Once enabled, the
camera will retain this setting even if it is rebooted.
The camera supports 1, 2, and 4 taps to increase the read rate of the data off the image sensor and increase the frame
rate. There are also 3 clock configurations – Quarter (approx.), Half (approx.), and Full. The camera can be configured to
operate off standard USB power, USB Y power or External Power under the conditions shown below.
* To use USB Y cable the camera must be set to High Power USB Mode.
Operation of the camera in the high power mode state can be done with one of the optional power supply options you may
have ordered with your camera: La2000PK (GPIO Adapter + International Power Supply) or La2000PIOK (GPIO Adapter
with IO leads + International Power Supply) OR you can use the USB Y cable provided with the camera enabled in High
Power USB mode.
Note: Not all USB cards/controllers are designed to support this type of power configuration for a Y cable. If the camera is
not operating at full power (LED is solid green when idle) then try alternate USB ports or cards.

Notes:
1) For programmed exposure mode the trigger will correspond to the 'trigger rising' signal. The 'trigger falling' is
programmed such that the desired exposure time is obtained. The exposure granularity is 1.28us
2) Data compiled for full frame size at the fastest readout setting. For slowest setting Tready will be longer. For sub
windows Tready will be shorter.
3) This delay is the minimal exposure time and may be reduced at the expense of FPN. Contact Lumenera for more
information.
