Computer Requirements for Linea GigE Cameras
The following information is a guide to computer and networking equipment required to support the
Linea GigE camera at maximum performance. The Linea GigE camera series complies with the
current IPv4 Internet Protocol, therefore current Gigabit Ethernet (GigE) equipment should provide
trouble free performance.
Host PC System
Operating System: Windows Vista, Windows 7/8 (either 32-bit or 64-bit for all) 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. Optimal settings will be system dependent.
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 Linea 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.
IEEE 802.3x Pause Frame Flow Control
Ethernet Switches supporting Full-duplex IEEE 802.3x Pause Frame Flow Control must be used in
situations where multiple cameras may be triggered simultaneously. In such a case the NIC
maximum bandwidth would be exceeded if there was no mechanism to temporarily hold back data
from cameras. Linea GigE cameras support the IEEE 802.3x pause frame flow control protocol
automatically so that images from many cameras can be transmitted through the switch to the NIC
efficiently, without data loss. As a working example, one such switch tested at Teledyne DALSA is
the NETGEAR GS716T.
Important: The maximum virtual frame rate possible from a large number of cameras which are
simultaneously triggered will depend on the camera model, frame size, and network configuration.
Additionally using Pause Frame may change the Jumbo Frame value which maximizes data
throughput. Each imaging system should be tested for data rate maximums.
