Installing the Genie Camera
Warning! (Grounding Instructions)
Static electricity can damage electronic components. Please discharge any static electrical charge by touching a
grounded surface, such as the metal computer chassis, before performing any hardware installation.
If you do not feel comfortable performing the installation, please consult a qualified technician.
GigE Network Adapter Guideline
If the computer to be used with the Genie camera does not have a Gigabit network adapter or second built in Gigabit
NIC, a PCI bus Gigabit NIC needs to be installed. Typically under Windows XP the PCI Gigabit NIC is recognized
automatically when Windows boots. An example of a high performance NIC is the Intel PRO/1000 MT adapter.
Review the NIC documentation concerning any special driver required for Windows. Install the PCI bus Gigabit
NIC as described by the NIC manufacture's documentation.
The Genie camera has been tested with a variety of Gigabit network adapters, both built into the system
motherboard and as third party PCI adapters.
Supported Network Configurations
The Genie obtains an IP address using the Link Local Address (LLA) or DHCP, by default. If required, a persistent
IP address can be assigned (see "
The LLA method automatically assigns the Genie with a randomly chosen address on the 169.254.xxx.xxx subnet.
After an address is chosen, the link-local process sends an ARP query with that IP onto the network to see if it is
already in use. If there is no response, the IP is assigned to the device, otherwise another IP is selected, and the ARP
is repeated. Note that LLA is unable to forward packets across routers.
Alternatively, if a DHCP server is present on the network, the Genie is going to issue a DHCP request asking for an
IP address. The DHCP server will then provide the Genie an IP address.
Running the Network Configuration Tool" on page 26).
Using Genie with Ethernet Switches
Examples where a Gigabit Ethernet switch would be used are:
• Multiple Genie cameras are controlled by one computer and a single NIC (running multiple instances of
CamExpert as an example of the control program).
• Multiple Genie cameras are individually controlled by multiple computers, all located on the same subnet.
In these cases the Ethernet switch is a transparent device. The device discovery process finds all Genie cameras, and
presents them as ready to be controlled by an application such as CamExpert.
Genie Monochrome Series-GigE Vision Camera Installing the Genie Camera • 17
Using Genie with a VLAN Ethernet Switch
An Ethernet switch supporting VLAN (Virtual Local Area Network) allows multiple isolated subnets to exist on the
same switch.
Within each VLAN group, the Genie camera and controlling computer will behave identically as if connected to a
simple Ethernet switch. But each VLAN group is isolated from each other, Therefore a Genie in one VLAN group
is never seen by a computer on a different VLAN group.
VLAN Ethernet Switches support configuration as Port-based or TAG VLAN groups. Port-based groups are
typically easier to configure. Review your Ethernet switch manual for information on its factory default VLAN
settings and configuration method.
Installation Overview & Preparations
The Genie camera installation generally follows the sequence described below. Detailed installation instructions
follow this overview.
Network and Computer Overview
• Genie needs to connect to a computer with a GigE network adapter, either built in on the computer
motherboard or installed as a third party PCI adapter.
• Laptop computers with built in GigE network adapters may still not be able to stream full frame rates from
Genie, especially when on battery power. Thorough testing is required with any laptop computer to determine
the maximum frame rate possible (see "
• Genie also can connect through a Gigabit Ethernet switch. When using VLAN groups, the Genie and
controlling computer must be in the same group (see "
• If Genie is to be used in a Sapera development environment, Sapera LT needs to be installed, either before or
after the Genie software package. If Genie will be used in a GenICam™ environment, Sapera or Sapera runtime
is not required and you need to follow the installation instructions of the third party GenICam compliant
package.
• Install the Genie Framework software package if not using a third party GenICam compliant package. Also
install Sapera Run-time with CamExpert to control the Genie.
• The Windows Firewall exceptions feature is automatically configured to allow the Sapera GigE Server to pass
through the firewall.
• Computers with VPN software (virtual private network) may need to have the VPN driver disabled in the NIC
properties. This would be required only on the NIC used with the Genie. Testing by the user is required.

Status LED Codes
The camera is equipped with a LED to display the operational status of the camera. When more than one condition
is active, the LED color indicates the condition with the highest priority (such as an acquisition in progress has more
priority than a valid IP address assignment). The following table summarizes the LED states and corresponding
camera status.

Troubleshooting" on page 101 for network
Optimizing the Network Adapter used with Genie
Most Gigabit network interface controllers (NIC) allow user modifications to parameters such as Adapter Buffers
and Jumbo Frames. These should be optimized for use with the Genie during the installation.
Increasing Adapter Buffers and Jumbo Frames
Adapter Buffers (receive descriptors): Under certain conditions the host PC system CPU may be very busy with
tasks other than the imaging application. Incoming image packets remain in the PC memory allocated to store
packets instead of immediately being copied into the image buffer. By increasing the NIC host buffers, more
incoming image packets can be stored by the NIC before it must start discarding them. This provides more time for
the PC to switch tasks and move image packets to the image buffer.
Not all network boards allow increasing their buffer count and even among those that do, such as the Intel NIC,
different versions will have different maximum receive descriptor values. Refer to the NIC user documentation for
details on configuring this parameter. The procedure in this section shows how to increase the number of packet
buffers for one version of Intel network adapter.
Jumbo Frames: With good gigabit Ethernet connections with minimal packet resend conditions, host computer
performance can be further improved by increasing the data packet size. Each streaming video packet causes an
interrupt in the host computer. Therefore increasing the packet size reduces the CPU usage percentage required to
handle video data from Genie.
Before the Genie is configured to use larger data packets, the NIC used with the Genie must be configured to allow
Jumbo Frames. The procedure in this section describes increasing the size of Jumbo Frames for one version of Intel
network adapter.
The screenshot below shows that the Genie device was found and there is no IP conflict. The Maximum Packet Size
field is highlighted in yellow, indicating that Jumbo Frames are not enabled on the NIC used with the Genie or that
the control application is forcing a safe packet size. Using a larger packet size improves host CPU performance,
which can be critical when using multiple Genie devices. Note that the Maximum Packet Size field is updated only
when an application such as CamExpert communicates with the Genie.

Because image transfers require considerable bandwidth through the NIC, it is recommended that a separate Gigabit
Ethernet NIC for the Genie camera be used. Connections to the Internet or to a corporate network should be through
a different NIC.

About the User-Defined Camera Name
The Genie can be programmed with a user-defined name to aid identifying multiple cameras connected to the
network. For instance, on an inspection system with 4 cameras, the first camera might be labeled “top view”, the
second “left view”, the third “right view” and the last one “bottom view”. The factory default user name is set to
match the camera serial number for quick initial identification. Note that the factory programmed Genie serial
number and MAC address are not user changeable.
When using CamExpert, multiple Genie cameras on the network are seen as different "Genie_M640_x" devices.
Click on a Genie device user name to select it for control by CamExpert.
An imaging application uses any one of these attributes to identify a camera: its IP address, MAC address, serial
number or User Name. Some important considerations are listed below.
• Do not use the camera's IP address as identification (unless it is a persistent IP) since it can change with each
power cycle.
• A MAC address is unique to a single camera, therefore the control application is limited to the vision system
with that unique camera.
• The User Name can be freely programmed to clearly represent the camera usage. This scheme is recommended
for an application to identify cameras. In this case, the vision system can be duplicated any number of times
with cameras identified by their function, not their serial numbers or MAC address.

Gain and Black Level

Genie Monochrome Series-GigE Vision Camera Operational Reference • 35
Gain and Black Level Controls
The Genie series of monochrome cameras provide gain and black level adjustments for the analog signal from each
CCD pixel, before the analog to digital conversion. The software gain and black level controls can make small
compensations to the acquisition in situations where lighting varies and the lens iris can not be easily adjusted. The
user can evaluate Gain and Black Level by using CamExpert.
Features and limitations are described below.
• Gain is expressed in decibels (dB). Range from -6dB to +12dB in 0.1dB increments. Gain is a multiplication
factor to the analog signal (i.e. exposure) before digitization.
Note that a gain of 6dB is a multiplier of 2 (doubles the level).
• Increasing gain increases the amplitude of the analog video signal but also increases the sensor analog noise
proportionately, before analog to digital conversion.
• Note: Doubling gain does not necessarily double the digital data due to the Black Level Offset value as
described below.
• Black level offset is applied to the sensor analog signal to shift the DC level of the video signal. Black level is
an additive offset to the analog video signal before digitization.
• Black level offset increases the brightness of the video signal equally. Therefore any area of the video that is
black will brighten to some gray level as offset is increased.
• Black level offset is expressed as a number ranging from -128 to 127. The offset is achieved as a change in the
analog signal from the sensor where a control number change of 1 is 1/16
change. In other words, a control change of 16 is required for each change in pixel value, therefore a maximum
control value of 127 will cause a black pixel (00) to have a gray value of about 8.

Vertical and Horizontal Cropping can be combined to grab only a region of interest (ROI). Besides eliminating post

CamExpert Image Buffer and ROI Parameters
CamExpert provides controls to configure acquisitions via the Image Buffer and ROI Parameters tab. The image
buffer can be easily cropped as desired. Below is the CamExpert dialog and parameter descriptions follow.
Parameter Description
Pixel Format For the Genie Monochrome series, the image buffer format is Monochrome 8-bit or 10-bit.
Width (in Pixels) Displays the image buffer width (X axis), in pixels.
Height (in Pixels) Displays the image buffer height (Y axis), in pixels.
OffsetX (in Pixels) Specifies the offset in X, from the left of the image, when using an ROI. The image buffer
width is automatically adjusted to compensate for this offset.
OffsetY (in Lines) Specifies the offset in Y, from the top of the image, when using an ROI. The image buffer
height is automatically adjusted to compensate for this offset.
Image Flip Enables hardware based horizontal image flip.
Note: When operating in binning mode, the resolution is halved and the coordinate system is scaled accordingly.
For instance, an OffsetX of 20 pixels at nominal resolution is equivalent to an OffsetX of 10 pixels with
horizontal binning enabled.
40 • Operational Reference Genie Monochrome Series-GigE Vision Camera
Binning
Binning is the process where the charge on two (or more) adjacent pixels is combined. This results in increased light
sensitivity since there is twice the sensor area to capture photons. The sensor spatial resolution is reduced but the
improved low-light sensitivity plus lower signal-noise ratio may solve a difficult imaging situation. The user can
evaluate binning by using CamExpert.
Genie supports horizontal and vertical binning independently, by a factor of 2 in each axis. Specifically if horizontal
binning only is activated, a nominal 640x480 image is reduced to 320x480. If vertical binning only is activated, the
image is reduced to 640x240. With both binning modes activated, the resulting image is 320x240.
Vertical binning also provides an increase in maximum acquisition frame rate. The frame rate increase depends on
the camera model and amount of vertical cropping used. The following graphic illustrates binning.

programmed function call message by the controlling computer. These triggering modes are described below.
• Free running (trigger disabled): The Genie free-running mode has a programmable internal timer for frame
rate and a programmable exposure period. Frame rate is 0.1 fps to the maximum supported by the sensor.
Exposures range from 100 µs to a maximum also dependent on the current frame rate. This always uses
Synchronous mode where exposure is aligned to the sensor horizontal line timing.
• External trigger: Exposures are controlled by an external trigger signal. External signals are isolated by an
opto-coupler input with a time programmable debounce circuit. See "
following section provides information on external trigger timing.
• Software trigger: An exposure trigger is sent as a control command via the Ethernet network connection.
Software triggers can not be considered time accurate due to network latency and sequential command jitter.
But a software trigger is more responsive than calling a single-frame acquisition (Snap command) since the
latter must validate the acquisition parameters and modify on-board buffer allocation if the buffer size has
changed since the last acquisition.

Exposure Controls
Exposure Control modes define the method and timing of how to control the sensor integration period. The
integration period is the amount of time the sensor is exposed to incoming light before the video frame data is
transmitted to the controlling computer.
• Exposure control is defined as the start of exposure and exposure duration.
• The start of exposure can be an internal timer signal (free-running mode), an external trigger signal, or a
software function call trigger.
• The exposure duration can be programmable (such as the case of an internal timer) or controlled by the external
trigger pulse width.
• For the Genie camera, exposure control modes are "
External Trigger Programmable Exposure" on page 44 (timer) and "External Trigger Level-controlled
"
Exposure" on page 45 (trigger pulse width). Following are details for each mode.
Free-running Programmable Exposure
Genie is in a multifunctional free running mode with the following features:
• Internal trigger programmable from maximum sensor frame rate down to 0.1Hz.
• Exposure duration is user programmable (exposure maximum is dependent on the frame rate). Minimum
exposure is 100µs.
• Supports vertical and horizontal binning.
• Exposure synchronization timing is "
sensor horizontal line timing and the next acquisition is triggered by an internal programmable timer.
• Image readout is simultaneous where the grabbed image frame is readout during the next frame exposure time.
This allows for fastest possible frame rates. See the timing diagram below.

Synchronization Timing
Genie supports two types of sensor synchronization used to align the exposure to sensor timing:
• Synchronous Mode: Exposure is synchronous to the line timing of the sensor. Exposure granularity is 1µs and
the readout can be concurrent to the exposure for the fastest possible frame rate.
• Reset Mode: Timing is reset to initiate exposure of next frame. Exposure granularity is 1µs, but readout must
be sequential to exposure, reducing the maximum achievable frame rate.
Synchronous Mode
• Synchronous mode starts the exposure period aligned to the sensor horizontal line timing and the programmable
duration granularity is 1µs.
• In the case of the Genie M640, a horizontal line occurs every 31.77µs.
• Exposure duration is from a minimum of 100µs up to 4 sec.
• In this mode, sensor exposure and sensor readout of the previous frame's exposure occur simultaneously. This
allows operating the sensor up to its maximum frame rate.
• Any trigger received before the end of the exposure is ignored. The application can elect to receive messages
about ignored triggers. See "
• Since the external trigger is asynchronous with the Genie horizontal line timing, the frame exposure start is
subject to 1 horizontal line jitter.
Events" on page 63.
Synchronous Mode Timing example for Genie M640
46 • Operational Reference Genie Monochrome Series-GigE Vision Camera
Reset Mode
• Exposure starts immediately after a valid trigger. There is no jitter on the start of exposure.
• Exposure time is programmable or controlled by the trigger pulse width.
• Minimum exposure is 100 µs – maximum is 4 seconds, with control steps of 1µs.
• Sensor readout must complete before the next exposure can start. That is, exposure and readout are sequential.
Therefore, the maximum frame rate is lower than for Synchronous mode.
• Any external trigger received before the previous exposure/read out sequence is complete is ignored. An
application can elect to receive messages about ignored triggers. See "

Genie Processing Features
The Genie monochrome series of cameras support a number of functions to enhance acquisitions or perform real
time processing. Functions can be combined to solve specific imaging situations. The user can enable and evaluate
each operation by using CamExpert.
Lookup Table (LUT)
The Genie camera includes a user programmable LUT as a component of its embedded processing features. The
LUT is used for operations such as gamma adjustments, invert and threshold processes. CamExpert has a number of
built in LUT operations for the user to explore (see "
For monochrome sensors, the LUT table is a single 8-bit or 10-bit LUT (8/10-bit in, 8/10-bit out) as illustrated in
the following figure. Pixel data when read out of the sensor is passed through the LUT memory array, where the
new programmed pixel value is then passed to the Genie output circuit. The LUT data table is stored along with
other parameters with the user configuration function (see "
CamExpert LUT Controls" on page 87).

Flat Field (Image Shading) Correction
Image Shading correction, also know as Flat Field Correction is the process of eliminating small gain differences
between pixels in a sensor array. That sensor when exposed to a uniformly lit field will have no gray level
differences between pixels when calibrated flat field correction is applied to the image. The Genie camera stores flat
field correction data until power off or in its user setting state for recall at any time (see "
on page 32). Flat field correction data is composed of 8 bit gain and 8 bit offset coefficients.
The CamExpert Flat Field Correction tool allows calibrating. saving, and loading the flat field calibration data for
any Genie camera being controlled.
Before performing calibration, verify Genie acquisition with a live grab. Also at this time make preparations to grab
a flat light gray level image, required for the calibration, such as a clean evenly lighted white wall or non-glossy
paper. Note the lens iris position for a white but not saturated image. Additionally check that the lens iris closes well
or have a lens cover to grab the dark calibration image.
Flat Field Correction Calibration Procedure
Calibration is the process of taking two reference images, one of a black field – one of a light gray field (not
saturated), to generate correction data for images captured by Genie. Each sensor pixel data is modified by the
correction factor generated by the calibration process, so that each pixel now has an identical response to the same
illumination.
Start the Flat Field calibration tool via the CamExpert menu bar:
Pre-processing • Flat Field Correction • Calibration.
Power-up Configuration"
Flat Field Calibration Window
The Flat Field calibration window provides a three step process to acquire two reference images and then save the
flat field correction data for the Genie used. To aid in determining if the reference images are valid, a histogram tool
is provided so that the user can review the images used for the correction data.

CamExpert Flat Field Calibration Menu
• Click on the Advanced Setting button to change the default number of frames averaged for each calibration
step. The default value is 10 frames.
• Setup the camera to capture a uniform black image. Black paper with no illumination and the camera lens’ iris
closed to minimum can provide such a black image.
• Click on Acquire Black Image. The flat field calibration tool will grab video frames, analyze the pixel gray
level spread, and present the statistics. The desired black reference image should have pixel values less then 20.
If the results are acceptable, accept the image as the black reference.
• Setup the camera to acquire a uniform white image (but not saturated white). Even illumination on white paper
can be used, with a gray level of 128 minimum. It is preferable to prepare for the white level calibration step
before starting the calibration procedure.
• Click on Acquire White Image. The flat field demo will grab video frames, analyze the pixel gray level
spread, and present the statistics. The captured gray level for all pixels should be greater than 128. If acceptable
accept the image as the white reference.
• Click on Save. The flat field correction data is saved as a TIF image with a file name of your choice
(suggestions are the camera name and its serial number).

Internal Image Test Patterns
The Genie camera includes a built in test pattern generator that can be used to confirm camera Ethernet connections
or driver installations, without the need for a camera lens or proper lighting. The pattern generator inserts video just
after the sensor A/D converter, therefore Genie processing such as the LUT act on the generator images or on sensor
images.
CamExpert is used to easily enable and select the Genie test patterns. As shown in the following figure, select the
Sensor tab, then select one of the four patterns from the drop menu. Select live grab to see the pattern output.
Genie Test Pattern Selection – on Sensor Tab
The Genie test patterns are:
• Horizontal ramp: successive pixel's gray level is incremented by 1 to maximum pixel value then repeated until
the end of line. The gray level is reset to 0 on the following line.
• Vertical ramp: similar to the horizontal ramp, successive lines are incremented by 1 gray level then repeated
for the full frame.
• Moving diagonal ramp: combination of the 2 previous schemes, but first pixel in image is incremented by 1
between successive frames. This is a good pattern to indicate motion when doing a continuous grab.
• Purity: a purity pattern where all pixels have the same value. The gray value is incremented by one on
successive frames to maximum then repeated. This also provides motion for live grabs.

Network Controls & GigE Vision Parameters
This section describes how to optimize the network configuration for maximum Genie bandwidth. Optimization of
these parameters is highly dependent on the number of cameras connected to a NIC, the data rate of each camera
and the trigger modes used.
Important: Laptop computers may have issues even with a GigE NIC port, either built in or as a PCMCIA
device. This section describes optimizations for both desktop and laptop computers, but laptops may require
additional customization as described in section "
CamExpert GigE Vision Parameters
The Automatic Network Configuration mode sets parameters to a default state. The Optimize mode sets the packet
size to the maximum value as reported by the NIC driver. If this does not provide satisfactory performance, it is
possible to optimize transfers by manually setting the network configuration parameters. The following screen shot
of the GigE Vision Parameters shows the CamExpert control set to Manual. Descriptions for each parameter
follow.
Laptop Computer Networking Issues" on page 111.
Genie Monochrome Series-GigE Vision Camera Operational Reference • 65
Parameter Description
Network Configuration Mode Specifies the Network Configuration Mode as either Automatic, Manual, or Optimize. In
general use Optimize mode. Some computers, especially laptops, may require manual
optimization of network parameters.
The following parameters can be modified when Manual mode is selected.
Inter-Packet Delay (in sec) Specifies the inter-packet delay, in sec. The range of permitted values is 0.000000 to
0.065535. The inter-packet delay is the minimum time interval between two successive
packets. This can be increased if the NIC is unable to keep up with packet arrivals (thus
dropping packets–seen as video noise).
Packet Size (in bytes) Specifies the maximum packet size, in bytes. The range of possible values is 576 to 1500,
in increments of 4 bytes when the NIC does not support jumbo packet. The maximum is
currently 9000 bytes when jumbo packets are supported (see "
and Jumbo Frames" on page 24 to enable jumbo packets on the NIC). In most situations,
use the largest possible packet size supported by your network elements. In order to
support jumbo packets, all intermediate network elements must support them, otherwise
they will simply be silently discarded and no image data will reach the PC.
Heartbeat Timeout (in Sec) Specifies the heartbeat timeout, in seconds. The range of permitted values is 0.5 to 65, in
increments of 0.001 seconds. This is used by the camera to ensure the PC application is
still linked. If the heartbeat timeout expires, the camera will shutdown the connection to
the current application.
Maximum Packet Resend Sets the percentage of packets that can be resent for each frame. This is used to ensure
the streaming data (including resends) does not exceed the Ethernet link capacity. As an
example, a system capturing at 80 MB/s can allow 25% of packet resends without
exceeding 100 MB/s (about the maximum capacity of a gigabit Ethernet link).

Feature Type INT32
The feature list for type INT32 has an additional column 'Exponent' which defines the feature's native unit. This
exponent value is used as a unit multiplier so that the feature value is expressed as an integer, not a decimal number.
• As an example from the following table, the Genie frame rate is 60000 with an exponent of 3. Therefore the
frame rate native unit is mHz. The current value shown – 60000 mHz, is actually 60.000 Hz.

IP Configuration Mode Details
The following descriptions provide more information on the IP configuration modes supported by Genie. In general
automatic IP configuration assignment is sufficient for most Genie installations.
Link-Local Address (LLA)
• LLA is also known as Auto-IP. It is used for unmanaged networks including direct connections from a GigE
Vision device to a dedicated NIC.
• A subnet configured with LLA cannot send packets across routers but only via Ethernet switches.
• LLA is the recommended scheme when only one NIC is connected to GigE cameras. LLA is fully automatic
requiring no user input.
Ensure only one NIC is using LLA on your PC, otherwise IP conflicts will result.
• The NIC will automatically assign a random IP address within the 169.254.x.x subnet. The LLA protocol
ensures there are no conflicts with other devices through an arbitration scheme.
• The Windows NIC configuration must be set to DHCP (the typical default case) and no DHCP server must be
present on the network. Otherwise, an IP address gets assigned by the DHCP server. Windows will turn to LLA
when no DHCP server answers requests coming from the NIC.
• Windows takes up to 1 minute to obtain an LLA IP address. With Windows XP, with no DHCP server
involved, the network adapter icon in the system tray (in Windows XP) typically shows "limited or no
connectivity".
This is normal (see Microsoft KB article #892896) and indicates that the network does not have connectivity
beyond routers.
• Windows and Genie are still running the DHCP process in the background. If a DHCP server becomes
available on the network, the NIC will get a DHCP assigned IP address for the connected device but
connections on the LLA IP address will be lost.
• Important: If the host system has multiple NIC devices configured with LLA, then the communication stack
cannot accurately resolve which NIC to forward an IP packet on the 169.254 segment. Limit the number of NIC
configured using LLA to one interface. See "
on page 103 for additional information.
• Use the DALSA Network tool to change the Genie from the default DHCP/LLA mode to Persistent IP mode
when required, such as when there are multiple NIC devices with Genie connected to each. Note that DALSA
recommends DHCP/LLA as the mode of operation where a switch is used to connect multiple Genie devices.
Genie Monochrome Series-GigE Vision Camera Network Tools • 77
GigE Server Warning Example 1a: IP error with multiple NICs"
DHCP (Dynamic Host Configuration Protocol)
• This Genie IP configuration mode requires a DHCP server to allocate an IP address dynamically. The Genie
must be configured to have DHCP enabled. This is the factory default settings.
• The DHCP server is part of a managed network. Windows XP itself does not provide a DHCP server function.
A dedicated DHCP server is required. Open-source DHCP server software can be found on the Internet, but
they might not provide the same level of functionality as commercial-grade DHCP servers.
• A DHCP server is recommended where there are multiple NIC ports with multiple GigE Vision devices
attached. Each NIC ports must use a different subnet to avoid IP address conflicts (see "
Example 1a: IP error with multiple NICs" on page 103).
• Under Windows, a NIC is configured in DHCP mode by default. If no DHCP server is present on a given
subnet, Windows will revert to LLA as explained in the section above.
• Ensure that a different subnet is assigned to each NIC on the network. Typical ranges are 192.200.x.x or
10.10.x.x for internal networks.
GigE Server Warning
Persistent IP
• This protocol is only suggested if the user fully controls the assignment of IP addresses on the network and a
GigE Vision camera is connected beyond routers.
• The GigE Vision camera is forced a static IP address. The NIC IP address must use the same subnet otherwise
the camera is not accessible.
• If the Genie camera is connected to a network with a different subnet, it cannot be accessed.
• The DALSA network configuration tool is used to set a persistent IP address.
• An example of a Persistent IP address assignment:
• Persistent IP = 192.200.1.1
• Subnet Mask = 255.255.0.0
• Default Gateway = 0.0.0.0
• Warning: an incorrect IP address assignment might make it impossible to connect to the camera. In such a case
the DALSA network configuration tool includes a function to recover a Genie camera with an unknown
persistent IP and set the Genie to the factory default setting, i.e. DHCP/LLA mode. The Genie MAC address
must be known to use this function. See "
GigE Server Warning Example 2: Subnet Mask or IP error" on page 105.
"
• For GigE Vision applications the FORCEIP command is used to force a new persistent IP or to change the IP
configuration protocol. The Genie MAC address must be known to use the FORCEIP command.

Network Configuration Tool
The Network Configuration tool provides information on all network adapters installed in the system and any
connected GigE Vision devices. For the Genie, the tool allows a simple method to assign a User-Defined name and
also to set a Persistent IP address instead of the default DHCP/LLA assigned IP address. Using this tool, Genie
network configurations can be easily made without having to use any Windows Control Panel application.
Important: Any changes made with this tool will update the Genie flash memory. Do not remove power from the
Genie camera for a minimum 10 seconds. Then cycle the Genie power to load the new flash settings.
Quick Genie Network Configuration
• Start the Network Configuration program from the windows start menu: Start•Programs•DALSA•Sapera
Network Imaging Package•DALSA Network Configuration Tool.
• The left display window will show all installed network adapters and any connected Genie camera.
• Click on a Genie camera to see information such as MAC address, current IP address, serial and firmware
numbers.
• Click in the User Defined Name edit box and change the Genie name as required. Click on the Update button to
write into the Genie memory.
Genie Network Information
• Select the Device Configuration tab to switch from the default IP configuration mode DHCP/LLA to
Persistent IP mode (only if required).
• With Persistent IP mode selected enter the desired IP address, subnet mask, and default gateway.
Important: do not forget the persistent IP address you assign, else the camera can not be controlled.

System Information and Configuration
Select the system icon (the computer symbol) in the left pane to display current system information which may be
required when documenting Genie installations. There are no user changeable fields in the System Information tab.
In the right hand pane click on the System Configuration tab. By default the Sapera GigE Server is added to the
Windows Firewall exception list. This function is performed automatically when the Genie software package is
installed. This ensures the Windows Firewall remains active (if it was enabled) without having to individually put
each Genie application program in the exception list.
System Firewall Configuration
If the computer is using a different firewall software package, refer to that firewall's software manual to allow the
Sapera GigE Server to have access through it.
Alternatively, it is possible to exclude a specified NIC from using the firewall. The NIC dedicated to the Genie
camera does not need Windows firewall. See "

Network Card Information and Configuration
Select a network card icon in the left pane to see the NIC configuration parameters. The Network Configuration tool
ensures that no two NIC devices installed in the computer are on the same subnet, since that would create a conflict.
A warning message is displayed in such a case, indicating that a settings change is required for one of the NIC.
NIC Information
NIC IP and Network Imaging Driver Assignment
For each NIC, it is possible to configure the IP configuration mode (either DHCP/LLA or Persistent IP) if required
via the NIC Configuration tab.
Warning: Changing the NIC IP address may put it on a different subnet than the Genie. Changing the NIC IP
configuration first might cause the case where the camera becomes inaccessible from the NIC.
The proper sequence is to first change the camera IP configuration then change the NIC IP.
Genie Monochrome Series-GigE Vision Camera Network Tools • 81
After installation, all system NIC devices have the Sapera Network Imaging driver enabled. Only the NIC
connected to a Genie camera requires the Network Imaging driver enabled to capture images from Genie. The
Network Imaging driver streams image data efficiently to image buffers.
Select other NIC devices in the system and disable the Network Imaging Driver if they are not used with a Genie
camera.
Recovering a Camera with an Unknown Persistent IP
When a Genie camera has been configured with a persistent IP address, that camera can not be controlled if its IP
address has been lost or forgotten. The DALSA Network Configuration tool provides a function to recover cameras
and reset them back to the DHCP/LLA mode. The camera can also be set to a new persistent IP address immediately
if required.
Important: To recover a Genie camera, the camera MAC address must be known. DALSA ships all Genie
cameras with a label stating its serial number and MAC address. Additionally the NIC connected to the Genie
must be configured for LLA mode.
To recover a Genie:
• Start the Network Configuration program from the windows start menu: Start•Programs•DALSA•Network
Interface•DALSA Network Configuration Tool.
• From the menu bar click on Advanced and then on Recover Camera.
• On the dialog enter the camera MAC address and click the Recover Camera button.

Genie camera for a minimum 10 seconds.
Sapera GigE Server Details
This section provides additional details on the GigE Server not covered in the Genie installation section of this
manual. Generally the Genie automatic installation requires no user intervention.
• The Sapera GigE Server implements the GigE Vision Control Protocol (GVCP). This provides the interface to
generate GVCP messages to control and configure a GigE Vision device.
• GigE Server handles the heartbeat messages, allowing an application in development, to be single-stepped
while in debug mode, without loss of the camera connection.
• GigE Server is a single application going through the firewall. This simplifies firewall settings as only this
application needs to be listed in the firewall exceptions.
• The GigE Server periodically rescans the network to discover any new camera that might have been added to
the network. This will also identify devices removed.
• When required, it is possible to disabled the GigE server. A Sapera application will then directly be linked to
the library responsible for GigE Vision control channel communications. This can be used to minimize interprocess communications.
• The GigE Server Status window provides valuable information about the GigE Vision devices present on your
system (see "
Troubleshooting" on page 101).

RJ45 LAN Ethernet Connector Details
The RJ45 LAN connector has two LEDs for network status conditions.
The LED color codes are as follows.
Network Connection Network Activity
Green 100Mbps Off no network activity
Orange 1000Mbps Yellow typically blinking – active
Network Connection Network Activity
The Genie LAN connector is a standard Ethernet socket. Use CAT5e or CAT6 certified Ethernet cables. CAT5e
cable is rated for 100 MHz spectral bandwidth but CAT6 cable is rated for a 200 MHz spectral bandwidth with less
signal attenuation, therefore strongly recommended for long connection lengths.
The interconnection Ethernet cable can be either Straight Through or Crossover cable type. The Gigabit Ethernet
standard for devices defines that they will auto-negotiate send and receive channels, eliminating the need for users
to use a specific Ethernet cable type.

Optical Considerations
This section provides an overview to illumination, light sources, filters, lens modeling, and lens magnification. Each
of these components contribute to the successful design of an imaging solution.
Illumination
The amount and wavelengths of light required to capture useful images depend on the particular application. Factors
include the nature, speed, and spectral characteristics of objects being imaged, exposure times, light source
characteristics, environmental and acquisition system specifics, and more. The DALSA Web site,
http://vfm.dalsa.com/, provides an introduction to this potentially complicated issue. Click on the Application
Support link and then select the CCD Technology Primer. Review “Radiometry and Photo Responsivity” along
with other sections of interest.
It is often more important to consider exposure than illumination. The total amount of energy (which is related to
the total number of photons reaching the sensor) is more important than the rate at which it arrives. For example,
2
5μJ/cm
Light Sources
Keep these guidelines in mind when selecting and setting up light source:
• LED light sources are relatively inexpensive, provide a uniform field, and longer life span compared to other
• Halogen light sources generally provide very little blue relative to infrared light (IR).
• Fiber-optic light distribution systems generally transmit very little blue relative to IR.
can be achieved by exposing 5mW/cm2 for 1ms just the same as exposing an intensity of 5W/cm2 for 1μs.
light sources. However, they also require a camera with excellent sensitivity.
Genie Monochrome Series-GigE Vision Camera Technical Specifications • 93
• Some light sources age such that over their life span they produce less light. This aging may not be uniform—a
light source may produce progressively less light in some areas of the spectrum but not others.
Filters
CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent infrared from distorting the
images you scan, use a “hot mirror” or IR cutoff filter that transmits visible wavelengths but does not transmit
wavelengths over 750nm. Examples are the Schneider Optics™ B+W 489, which includes a mounting ring, the
CORION™ LS-750, which does not include a mounting ring, and the CORION™ HR-750 series hot mirror.
Lens Modeling
Any lens surrounded by air can be modeled for camera purposes using three primary points: the first and second
principal points and the second focal point. The primary points for a lens should be available from the lens data
sheet or from the lens manufacturer. Primed quantities denote characteristics of the image side of the lens. That is, h
′
is the object height and h
The focal point is the point at which the image of an infinitely distant object is brought to focus. The effective focal
length (f
the distance from the image side of the lens surface to the second focal point. The object distance (OD) is the
distance from the first principal point to the object.
′
) is the distance from the second principal point to the second focal point. The back focal length (BFL) is

is the image height.
Magnification and Resolution
The magnification of a lens is the ratio of the image size to the object size:

=
h
By similar triangles, the magnification is alternatively given by:
fm'

These equations can be combined to give their most useful form:

Where m is the magnification, h’ is the image height (pixel size)
and h is the object height (desired object resolution size).
This is the governing equation for many object and image plane
parameters.

Example: An acquisition system has a 512 x 512 element, 10μm pixel pitch area scan camera, a lens with an
effective focal length of 45mm, and requires that 100μm in the object space correspond to each pixel in the image
sensor. Using the preceding equation, the object distance must be 450mm (0.450m).

Sensor Handling Instructions
This section reviews proper procedures for handling, cleaning, or storing the Genie camera. Specifically the Genie
CCD sensor needs to be kept clean and away from static discharge to maintain design performance.
Electrostatic Discharge and the CCD Sensor
Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide semiconductor (MOS) devices
and are susceptible to damage from electrostatic discharge (ESD).
Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the
window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity. When charge buildup
occurs, surface-gated photodiodes (SGPDs) may exhibit higher image lag or a highly non-uniform response, with
some pixels displaying a much higher response when the sensor is exposed to uniform illumination. The charge
normally dissipates within 24 hours and the sensor returns to normal operation.
Important: Charge buildup will affect the camera’s flat-field correction calibration. To avoid an erroneous
calibration, ensure that you perform flat-field correction only after a charge buildup has dissipated over 24 hours.
Protecting Against Dust, Oil and Scratches
The CCD window is part of the optical path and should be handled like other optical components, with extreme
care.
Dust can obscure pixels, producing dark patches on the sensor response. Dust is most visible when the illumination
is collimated. The dark patches shift position as the angle of illumination changes. Dust is normally not visible when
the sensor is positioned at the exit port of an integrating sphere, where the illumination is diffuse.
Dust can normally be removed by blowing the window surface using a compressed air blower, unless the dust
particles are being held by an electrostatic charge, in which case either an ionized air blower or wet cleaning is
necessary.
Oil is usually introduced during handling. Touching the surface of the window barehanded will leave oily residues.
Using rubber finger cots and rubber gloves can prevent oil contamination. However, the friction between the rubber
and the window may produce electrostatic charge that may damage the sensor.
Scratches can be caused by improper handling, cleaning or storage of the camera. When handling or storing the
Genie camera without a lens, always install the C-mount protective cap. Scratches diffract incident illumination.
When exposed to uniform illumination, a sensor with a scratched window will normally have brighter pixels
adjacent to darker pixels. The location of these pixels changes with the angle of illumination.
Genie Monochrome Series-GigE Vision Camera Technical Specifications • 95
Cleaning the Sensor Window
Even with careful handling, the sensor window may need cleaning. The following steps describe various cleaning
techniques to clean minor dust particles to accidental finger touches.
• Use compressed air to blow off loose particles. This step alone is usually sufficient to clean the sensor window.
Avoid moving or shaking the compressed air container and use short bursts of air while moving the camera in
the air stream. Agitating the container will cause condensation to form in the air stream. Long air bursts will
chill the sensor window causing more condensation. Condensation, even when left to dry naturally, will deposit
more particles on the sensor.
• When compressed air cannot clean the sensor, Dalsa recommends using lint-free ESD-safe cloth wipers that do
not contain particles that can scratch the window. The Anticon Gold 9”x 9” wiper made by Milliken is both
ESD safe and suitable for class 100 environments. Another ESD acceptable wiper is the TX4025 from
Texwipe.
• An alternative to ESD-safe cloth wipers is Transplex swabs that have desirable ESD properties. There are
several varieties available from Texwipe. Do not use regular cotton swabs, since these can introduce static
charge to the window surface.
• Wipe the window carefully and slowly when using these products.

Computer Requirements for Genie Cameras
The following information is a guide to computer and networking equipment required to support the Genie camera
at maximum performance. The Genie camera series complies with the current IPv4 Internet Protocol, therefore
current Gigabit Ethernet (GigE) equipment should provide trouble free performance.
Host PC System
• Pentium 4 system (or AMD equivalent) with 512 MB system memory.
• System motherboard without an embedded graphic card. Avoid using onboard video cards as they may
compete with other components for shared memory.
• High performance video card as either an AGP bus or PCI Express bus.
• Operating System: Windows 2000 SP1 and Windows XP are supported.
Network Adapters
• GigE network adapter (either add on card or on motherboard). The Intel PRO/1000 MT adapter is an
example of a high performance NIC. Typically a system will need an Ethernet GigE adapter to supplement
the single NIC on the motherboard.
• PCI Express adapters will outperform PCI adapters.
• Network adapters that support Jumbo Frames will outperform adapters with fixed packet size frames.
Laptop Information
• Laptop computers with built in GigE network adapters may still not be able to stream full frame rates
from Genie. Thorough testing is required with any laptop computer to determine the maximum frame rate
possible (see "
Laptop Computer Networking Issues" on page 111).
Ethernet Switch Requirements
When there is more than one device on the same network or a camera-to-PC separation greater than 100 meters, an
Ethernet switch is required. Since the Genie GigE camera complies with the Internet Protocol, it should work with
all standard Ethernet switches. However, switches offer a range of functions and performance grades, so care must
be taken to choose the right switch for a particular application. The following switches are expected to work with
the camera but manufacturers may change specifications and features at anytime:
• SMC (
• 3COM (
• Dlink (
• Cisco (
