122  Technical Specifications Genie HM-HC Series-GigE Vision Camera
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
 Operating System: Windows XP, Windows Vista, Windows 7, Windows 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.
Laptop Information
 Older 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 (refer to the DALSA Network Imaging Package user's manual).
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.
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. Genie 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 DALSA is the
NETGEAR GS716T.
Important: The maximum frame rate possible from a large number of Genie cameras which are simultaneously
triggered will depend on the Genie model, frame size, and network details. Each imaging system should be tested
for frame rate limits.
