LYNX GigE Vision Software Manual
1.0 Introduction
1.1 The Scope of this Software User’s Manual
This manual describes how to access and use features shared by Imperx’s growing family of
LYNX GigE Vision ( hereafter referred to as GEV ) cameras.
1.2 Related LYNX User’s Manuals
In addition to the shared features described in this manual, each LYNX GEV camera has
unique features relating to the type of image data it supports. These unique features are
described in the Lynx Hardware User’s Manual.
Note also that each LYNX GEV camera is one element of the LYNX Connectivity Solution.
As such, the cameras are shipped with two PC software packages: the LYNX IP Device
Driver (either the LYNX eBUS Optimal Driver or the LYNX eBUS Universal Driver); and
the LYNX GEV Software Development Kit (SDK – available in C++ or Visual Basic). These
software packages each have their own documentation.
In addition, Imperx offers two products that enhance LYNX Connectivity Solutions: LYNX
Hydra™ PC-to-PC Communications Software, and the LYNX High Memory Manager. Both
have their own documentation.
In summary, LYNX GEV cameras are supported by seven separate pieces of documentation:

2.0 Overview of LYNX GEV
2.1 Application Highlights
2.1.1
Functional Description
LYNX GEV cameras are feature rich, high-speed, high-resolution cameras that translate
imagery data into IP packets for transport over long-distance, high-speed, industry-standard
Gigabit Ethernet (GigE) networks. Cameras can be remotely accessed and controlled using
commercial GigE equipment.
LYNX GEV cameras can be used in a range of network types, including traditional point-topoint links, dedicated high-performance “machine-vision networks,” or standard corporate
Ethernet LANs (local-area networks). Regardless of the network type, direct connections
between cameras and host PCs can span up to 100 meters. With low-cost GigE LAN switches
or fiber, the reach is much further.

Security/Surveillance.
2.2 Network Compatibility
LYNX GEV cameras are fully compatible with industry-standard Ethernet LAN equipment.
In point-to-point connections, the cameras allow cameras and host PCs to be separated by up
to 100 meters without any intervening hardware. In networked configurations, with GigE
switches between cameras and PCs, or with fiber, the reach is unlimited.
For maximum network performance, use a non-blocking GigE switch. For applications
requiring peak bandwidths of less than 100 Mb/s, switches with non-blocking, 100-Mb/s ports
can be used.
To ensure efficient, highly reliable transfers where data is never lost, LYNX GEV cameras
add a protocol layer on top of the standard UDP/IP (User Datagram Protocol/Internet
Protocol) communications protocol. This LYNX GEV Protocol Layer verifies the receipt by
cameras and PCs of all video and command packets.
To maximize bandwidth availability, packets do not return an acknowledge message to the
camera, but are monitored by the LYNX application library. If a packet is missing or corrupt,
the application library transparently requests the camera to resend it.
LYNX GEV cameras support the multicast, or simultaneous transfer, of image data to more
than one host PC. One of the host PCs is configured as the master; the others are slaves that
receive data as configured and triggered by the master. To support multicasting, Layer 3 or –
in some cases, Layer 2.5 – GEV switches are required between the LYNX and the host PC.
Lower-performing switches may translate the multicast request into a broadcast. In some
applications, broadcasts may be sufficient. See ‘Equipment Requirements’, section 2.4 of this
manual for more details about which equipment to use.
2.2.1
LYNX eBUS Optimal Driver Mode
In high-performance mode, LYNX GEV cameras work with the LYNX eBus Optimal Driver
to transfer data between cameras and PCs with very low, predictable latency at rates of up to 1
Gb/s (100 MB/s). The video data is streamed directly into PC memory using almost no PC
CPU resources. This leaves the CPU free to process applications.
To achieve this performance level, PCs must be equipped with a GigE network interface (also
referred to as a network adapter) based on Intel’s 82540 chip. Many motherboard
manufacturers are designing this chip directly into their board in “LAN on the motherboard
(LOM)” implementations. Alternately, an Intel 82540-based network adapter, also known as a
network interface card, can be slotted into a PC. For more information about the equipment
needed to achieve the highest performance level, refer to ‘Equipment Requirements’ section
2.4 of this document.

Rev 1.0 6/21/2007
LYNX GigE Vision Software Manual
Note: The LYNX eBUS Optimal Driver supports LOM implementations, but the PCI
identification number for these may be different. Contact Imperx to obtain a driver
installation file compatible with LOMs.
2.2.2
LYNX eBUS Universal Driver Mode
The LYNX eBUS Universal Driver mode is recommended for applications where flexibility
is more important than performance, but more performance is required than can be achieved
using only the Windows network stack.
Similar to the drivers used in standard mode, the LYNX eBUS Universal Driver interoperates
with any vendor’s Ethernet network adapter. The driver shipped with the adapter is still
employed, but it communicates with the Filter Driver, instead of with the Windows network
stack.
All packets related to imaging are processed with high efficiency by the LYNX eBUS
Universal Driver. Other packets are forwarded to the Windows stack. In this way, a single
network adapter can support both an imaging application and normal corporate LAN
functions, such as web browsing and email.
2.2.3
Standard Driver Mode
In standard mode, LYNX GEV cameras interoperate with any vendor’s Ethernet network
adapter. The driver shipped with the adapter transfers the data to the Windows network stack,
which handles IP communications tasks.
Standard mode is recommended for applications where flexibility is more important than
performance. The Windows network stack uses significant levels of CPU processing power to
transfer data to memory, which can result in lost packets, severely degrading performance.
Standard mode is thus suitable for applications that require bandwidths of only 100 Mb/s or
less. If this mode is used with bandwidths of 1 Gb/s, application performance will greatly
degrade when CPU usage hits 100%. Additionally, at high rates like these, insufficient CPU
resources may be available to process or even display images.
2.2.4
Driver Comparison
The performance metrics in Table 1 may help users determine which driver mode best suits
their application requirements. The measurements were taken using an Intel P4 2.8 GHzbased PC with hyperthreading, 512 MB of memory, and Windows XP.
Although CPU performance and data transfer rates vary with PC configuration, relative
performance is roughly equivalent, independent of the PC.

Table 1: LYNX IP Device Driver Performance Comparison
With the hyperthreading CPU used in these tests, the 50% CPU usage measured for the native
Windows stack indicates that one complete processing thread was employed to transfer the
data. This leaves only one thread available for processing applications. By contrast, with the
LYNX eBUS Optimal Driver and the LYNX eBUS Universal Driver, one complete thread
and most of the second thread are available for applications processing.
2.3 Acquisition Features
The LYNX GEV camera family includes a wide range of models, each with it’s own frame
resolution and frame rate characteristics.
For more details about acquisition features, refer to the Lynx Hardware User’s Manual.
2.4 Equipment Requirements
2.4.1
PC Requirements
To achieve the highest performance level, LYNX GEV cameras must be used with the LYNX
eBUS Optimal Driver and the driver must be loaded into a PC with the following minimum
characteristics:
•
•
•
•
•
•
Processor: AMD Athlon XP 2000+ or Intel P4 2.0 GHz;
Memory: 512 MB DDR-RAM PC2700;
Motherboard: Mid-end without embedded graphic card;
VGA card: Nvidia GForce 2 or better (ATI not recommended); 1 2
GigE network adapter (either PCI card or LOM): Intel PRO/1000 MT family; and
Operating system: Windows 2K, Windows XP Professional, or SuSe Linux Ver. 8.2.
For standard performance, any Fast Ethernet or a GigE network adapter and its manufacturersupplied driver, as well as any AGP video card, can be used. For higher, mid-range
performance, the manufacturer’s driver can be used in tandem with the LYNX eBUS
Universal Driver.
1
Avoid using onboard video cards as they may compete with other components for shared memory.
2
Some ATI video cards will use a high amount of the PCI bandwidth and compete with other components, such
as the GigE network card. This may lower the expected data rate of applications.

2.4.2
Network Adapter Requirements
The LYNX eBUS Optimal Driver works only with network adapters based on the Intel 82546,
82541, and 82540 network chips. The driver will also function with adapters based on the
Intel 82544 chip, but these are not recommended due to bugs in the chip that can cause
control packets to be lost if sent while data is streaming.
The PCI ID for some OEM network adapters may not be automatically recognized by the
LYNX eBUS Optimal Driver. If this occurs, contact Imperx to obtain an updated INF file.
The following four Intel network adapters are recommended:

LAN on the motherboard (LOM) chips from Intel are also supported. Contact Imperx for
information on how to use these network chips with the LYNX eBUS Optimal Driver.
2.4.3
Ethernet Switch Requirements
Since LYNX GEV cameras comply with the Internet Protocol, the cameras 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 have been tested in-house for use with LYNX GEV cameras:
•
SMC (www.smc.com)

Note: Although these products are known to work with LYNX GEV cameras, their inclusion
in this manual does not guarantee they will meet specific application requirements.
2.4.4
Fiber-Optic Interface Requirements
In cases where no intervening switch is desired and camera-to-PC separations of more than
100 meters are required, a fiber-optic media converter can be used with LYNX GEV cameras.
The FlexPoint GX from Omnitron Systems (www.omnitron-systems.com) converts GigE to
fiber and vice versa. It supports multimode (MM) fiber over distances of up to 220 m (720 ft.)
and single-mode (SM) fiber up to 65 km (40 mi.) with SC, MT-RJ, or LC connector types.
Fiber-optic media converters from other manufacturers should also be compatible – even
those that convert Camera Link™ to fiber.
Note: Although these products are known to work with LYNX GEV cameras, their inclusion
in this manual does not guarantee they will meet specific application requirements.
2.4.5
Power Requirements
LYNX GEV cameras accept 4.5 V to 16 V power inputs using a 12-pin Hirose connector “HR
10A-10R-12P” (mating part “HR 10A-10P-12P”). Any DC power source providing sufficient
current drive should work. The following power supply is known to work:
12 V CUI Switching Supply: Model DSA-0151D-12.
Input:
100-240V
~47-63Hz

3.1.1
File Menu
The file menu lets you create and save commands for XML configuration files for your Lynx
GEV camera. The menu contains the following items:
New: This command is used to clear configurations and cached file names from the
Connection tab (if any previous open or save has been performed).
Open…: This command is used to open a new XML configuration file. It displays the file
open dialog for selecting the file.
Save/Save As…: This command is used to save the current configuration to an XML
configuration file. If no file has been previously opened or saved, the file save dialog will
be displayed to select the location and name of the new file.
Save adapter as index: This option lets you create XML configurtion files for a large
number of identical PCs. Normally, Lynx GEV saves the XML configuration with the
MAC address of the NIC. However, even with an identical PC, the MAC address of the
NIC will always differ (because MAC addresses are always unique). Instead of using the
MAC address, Lynx GEV creates a list of all the NICs on the PC and identifies the NIC
by the position on the list (index). Lynx GEV produces the same list for an identical PC,
so the position on the list lets you reproducibly identify a NIC (even if the PC has several
NICs).
Ignore connectivity information: This option lets you save or load an XML
configuration file without the information required to connect to a specific camera. By
removing that specific information, you can use the XML configuration file for an

Connection Options tab
Figure 3: Connection Options Dialog
The Connection Options tab lets you configure how the camera connects with the PC, the
duration of timeouts, and so on.
‘Default Timeouts & Packet size’ panel
Answer Timeout: The maximum time, in milliseconds, the camera can take to respond to
a command from the application.
Request Timeout: The maximum time, in milliseconds, the host PC waits to receive all
the packets for a single image.
Packet Size: The maximum packet size, in bytes, that the camera can use to send image
data to the application. When connected point-to-point with the iPORT High-Performance
IP Device Driver, the maximum value is 8128 bytes. In networked applications, the value
depends on the maximum packet size that can be accepted by the switches between the
camera and the host PC. If the switches can be configured to support jumbo packets, you
can use the jumbo packet configuration to reduce packet overhead in the host PC. A
packet size of 1440 bytes should work with all networking equipment.
First Packet Timeout: The maximum time, in milliseconds, the camera can take to send
the first packet of image data to the application. When zero, the timeout is calculated
automatically from the request timeout.

LYNX GigE Vision Software Manual
Packet Timeout: The maximum time, in milliseconds, the camrea can take to send
subsequent packets of image data to the application. When zero, the timeout is calculated
automatically from the request timeout.
Command Retry Count: The maximum number of times the Lynx GEV application
retransmits an unacknowledged command to the camera. When the application sends a
command to the camera, the camera transmits an acknowledge packet back to the PC
(application). If the application doesn’t receive the acknowledge packet within the time
specified by Packet Timeout, it retransmits the command. The retry count doesn’t include
the original command.
Automatic packet size detection: When enabled, the Lynx GEV application disregards
the Packet Size configuration and negotiates the optimal packet size with the IP Engine.
‘Default heartbeat settings’ panel
The heartbeat function lets the camera send data only when the host PC is properly
connected to the network. Using the heartbeat function keeps the camera from endlessly
transmitting data to a PC that has long since disconnected from the network (due to power
outage, network failure, etc.).
If the camera doesn’t receive a heartbeat signal before the configured maximum time, it
stops transmitting (as if it received a stop request). To restart transmission, the PC must
reconnect to the camera and explicitly start transmission.
Normally, the camera accepts heartbeat signals only from the PC to which it is connected.
However in Multicast mode, the camera accepts heartbeats from any PC because it can’t
tell which PCs are part of the multicasting group.Error! Bookmark not defined.
Heartbeat Expiration: The maximum time that the camera waits for a heartbeat signal
before stopping transmission. An expiration of 0 disables heartbeating.
Heartbeat Interval: The interval between the transmission of each heartbeat packet from
the PC to the camera. For proper operation, this value must be lower than the Heartbeat
Expiration.

a camera. When disabled, the application reports a time-out and waits for the
connection to return. Disabling this flag may help with wireless networks, where
connectivity isn’t always stable.
Interrupt Port Keep Alive (useful when a firewall is present): When enabled, the
application sends regular dummy packets to the camera. The packets keep your
firewall from automatically closing an idle connection after it times out.

Multi-Target: The sending mode used when connecting to camera. Note that this list box
shows all the possible modes, since the Lynx GEV application program can’t determine
the modes that are supported by the camera until the connection is made.
Unicast: In unicast mode, the camera sends images to a single PC, on request. This
mode is the default data sending mode.
Figure 13: Unicast illustration
Multicast: In multicast mode, the camera sends each frame to a multicasting group, as
triggered by the master PC.
Multicasting uses the IGMP (Internet Group Management Protocol) and requires an
IGMP-compliant switch. The switch maintains a group list containing the group’s IP
address and the IP addresses of all the PCs that have subscribed to the group. The
multicasting group’s IP address is 224.64.16.xx; the xx part is configurable. When the
switch receives a packet addressed to the group, it sends individual packets to all the
(PCs) IP addresses in the list. Note that the Lynx Filter Driver doesn’t support
multicasting. To learn more about IGMPv3, see RFC 3376 at www.ietf.org.

Figure 14: Multicast illustration
Multi-Unicast: This mode lets you send packets to multiple PCs without having an
IGMP-compliant switch. Where the switch maintained a group list in multicasting
mode, the camera maintains the list for multi-unicasting. The camera consecutively
sends each packet individually to each of the PCs, so a group of n PCs requires n times
the bandwidth compared to unicast.
Multi-unicast mode also lets you send a single image to a single PC, even if other PCs
are grabbing continuously.

Group address: The multicasting group IP address, used only in multicasting mode. The
usable IP addresses are restricted.Error! Bookmark not defined..
This application is the master: When enabled, the current PC will be the master client of
the camera. This applies to all modes, including unicast. When connecting a unicast client
as a slave, the Lynx GEV application program won’t be able to configure or trigger the
camera. This is useful when connecting to a camera that boots up in a streaming state.
Do not join group: Selects whether or not the multicasting master will join the group.
When the master doesn’t join the group, it won’t receive any image data from the camera.

This mode is useful when a master PC controls several multicasting cameras, and the
combined bandwidth exceeds the capacity of the PC’s Ethernet link and/or PCI bus. The
master simply configures the cameras and then triggers them to stream their data.
Network Ports…: This dialog lets you configure the UDP ports.
Figure 16: Network Stack Port Selection Panel
When using the network stack to bring data into the PC, you can specify which UDP ports
will be used to connect to the camera. The default port value of 0 causes the network stack
to choose any available port. These values aren’t used when using the Lynx HighPerformance IP Device Driver or the Lynx Universal IP Filter Driver.
In some cases, you may want to force a port number to one or all of the three ports. For
example, you can save the camera’s configuration to flash while it is streaming. When the
camera boots up the next time, it starts sending frames right away. To ensure that the same
ports are used, specify each port rather than letting the camera choose available ports.
Command Port: The port over which commands from the host PC to the camera (and
acknowledgements from the camera) are sent.
Data Port: The port over which images are sent from the camera to the PC. For cameras
with multiple channels, channel #0 uses dataPort; channel #1, dataPort + 1.
Interrupts Port: The port over which the camera sends interrupts to the host PC.

3.7.2 Statistics pane
The Statistics pane provides a running count of the images and image-related errors for both
valid and invalid images. Valid images may have errors if Keep partial images is
checked.Error! Bookmark not defined.
Count: The total number of images.
Frame overrun: The camera needs a few clock cycles to finish a frame. This error occurs
if a new frame starts before the camera has finished the previous frame.
Grabber FIFO overrun: The grabber ran out of RAM while acquiring an image. At least
one section of the image is missing.
Image dropped: The total number of images dropped by the IP engine. When a camera
transmits images faster than the IP Engine can relay them to the PC, the IP Engine drops
the image. The next image has an image-status bit set to indicate that the previous image
was dropped.
Partial line missing: The number of times a part of a line was missing in the IP Engine
(i.e. not sent by the camera). The value is incremented only once per image, even if all
lines in the image are partial.
Full line missing: A complete line is missing from a frame. This error may occur with
images of variable length.
Expected resend count: The number of packets (image pieces) that were re-requested
and received.
Ignored packet count: The number of packets received by the PC that were ignored due
to the lack of an available buffer. Packets unrelated to IP Engine data aren’t counted.
Lost packet count: The number of packets that were expected, but weren’t received
within a certain time limit or in the expected order.
Resent request count: The number of packets re-requested by the PC.
Start packet count: The number of packets the PC received (and ignored) while waiting
for the first image packet.
Unexpected resent count: The host PC re-requests packets that haven’t arrived within its
time limit. If both packets ultimately arrive, the second is counted as unexpected and
discarded.
3.7.3 Errors pane
Error Types: The total number of errors. Click Show to see a detailed list in the Error
Type dialog.
Missed Image Ids: The image ID of the last missed image. Click Show to see a full list in
the Missed Image dialog.
