Installing the camera (GigE)
42 Goldeye G/CL Technical Manual V4.2.0
Optimize system performance
The NIC should be adjusted to improve system performance when using a GigE
Vision camera. This performance is related to minimizing CPU usage and dropped
or resent packets.
Edit the NIC driver properties according to the values in the following table. The
names and availability of the properties listed may vary depending on NIC
manufacturer and model.
Default packet size
The default packet size of Goldeye G cameras is 8228 bytes. The host NIC needs to
support a packet size of equal or larger size to stream from the camera.
NIC settings
The NIC settings may also vary depending on your system configuration and the
NIC manufacturer.
For desktop systems, use a PCI Express bus NIC. For laptops, use an expansion slot
via an ExpressCard®.
A list of recommended NICs is available on our website. See the Hardware
Selection for Allied Vision GigE Cameras application note.
Enabling jumbo packets
The properties listed for the NIC may include either Jumbo Packet or Jumbo
Frames depending on the manufacturer. If neither is listed under properties, your
network card may not support this feature. You must use a NIC that supports
Jumbo Frames or Jumbo Packets.
To enable jumbo packets
1. Click the Start icon and select Control Panel in the menu.
2. Click View by Large Icons and select Device Manager in the list.
