Recommended network card settings
Due to the large amount of data that Ranger3 delivers per second, it is required to con‐
nect the camera(s) to the PC using a separate Gigabit Ethernet network, without other
interfering traffic.
The Network interface card (NIC) must support Gigabit Ethernet, and it is recommended
that the NIC supports Ethernet Jumbo frames. Ethernet Jumbo frames are frames with
more than 1500 bytes of Ethernet payload. Sending and receiving Ethernet Jumbo
Frames can give a performance increase due to lower PC CPU usage.
The Ranger3 camera has mainly been tested using network interface cards from Intel.
See the tables below for recommended network settings. Note that the names of the
settings may differ depending on NIC or driver version.
Receive buffers
Recommended setting
512 or more
Default setting
256
Maximum setting
2048
Jumbo frames
Recommended setting
>4200
Default setting
disabled
Maximum setting
16128
When using Jumbo frames the camera can support up to 4096 bytes of image data in
each data package, which corresponds to 4200 bytes per Ethernet frame.
Camera IP settings
The GigE Vision
®
standard dictates that the factory default setting for devices is IP con‐
figuration using DHCP. If no DHCP server is found, the default for devices is to assign a
Link-Local Address (LLA), also called a Zero Configuration IP, on the format 169.254.x.y.
It is recommended to define a persistent IP address which can be used when a device
boots. Which IP configuration option that is used when a device boots is dictated by the
TransportLayerControl
parameters,
see "Editing IP settings", page 53
Ranger3 also supports setting a static IP using the GigE Vision
®
forceIP method. This IP
address is not persistent, which means it is lost at power-off,
.
Symptoms of possible problem
Receive buffers Symptoms of too low setting: Multiple consecutive packets are lost,
e.g. 31 consecutive packets are lost.
Symptoms of too high setting: Use of memory increases.
Jumbo frames
Symptoms of too low setting: The camera will use a smaller frame
size, which implies higher CPU load on the PC.
Symptoms of too high setting: If you use a switch that is unable to
support Jumbo Frames connected between the camera and the PC, it
is impossible to receive streaming data from the camera.
IP settings
If the device and the NIC is not connected to the same DHCP server,
or only one end is connected to a DHCP server, the device can not
assign a correct IP,
