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:

• Lynx Hardware User’s Manual

• LYNX GEV Software User’s Manual (this manual)

• LYNX GEV Driver Manual

• LYNX GEV Advanced Driver Configuration

• Reference Manual, the LYNX C++ Software Development Kit

• Reference Manual, the LYNX Visual Basic Software Development Kit

• User’s Manual, LYNX High Memory Manager

• Reference Manual, LYNX Hydra PC-to-PC Communications Software

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-to-

point 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.

2.1.2 Features

• Most flexible, high-performance GEV camera in its class

• FPGA (field programmable gate array)-based IP Protocol Camera for converting video

data to IP packets (no software-based operating system)

• On-board, Intel 82540 GigE networking chip

• Fully compatible with industry-standard Ethernet LAN equipment, including GigE

and Fast Ethernet equipment.

2.1.3 Programmability

• Access to all camera commands via IP port

• Remote control of cameras using a single PC

• Comprehensive LYNX Software Development Kit (SDK) for integrating the LYNX

GEV camera into custom systems

• Field upgradeable software, firmware and lookup tables through the IP link

2.1.4 Applications

LYNX GEV cameras are ideal for applications that need to transfer large amounts of video

data from a camera to a local PC or via a LAN to a remote PC. These include:

• Factory automation

• Industrial inspection;

• Post and parcel sorting;

• Web inspection;

LYNX GigE Vision Software Manual

• Medical imaging;

• Intelligent traffic systems; and

• 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.

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 GHz-

based 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.
