Recommended Network Card
Settings
C Recommended Network Card Settings
Due to the large amount of data that the Ranger delivers, it is required to connect them to
the PC using a separate Gigabit Ethernet network, without other interfering traffic.
Network card interface (NIC) must support Gigabit Ethernet, and it is recommended that
the NIC supports Ethernet Jumbo frames. Sending and receiving Ethernet Jumbo Frames
can give a performance increase due to lower PC CPU usage.
Ranger cameras have mainly been tested using network interface cards from Intel. See
table below for recommended network settings. Note that the names of the settings may
differ depending on NIC or driver version.
Table C.2 – Recommended settings
Intel Driver
Receive Buffers
Recommended setting 512 or more
Default setting 256
Maximum setting 2048
Jumbo Frames
Recommended setting 4500 (>4100)
Default settings disabled
Maximum setting 16128
Note: The maximum frame size used by the Ranger is set by the Max package size pa-
rameter. This parameter is by default set not to use Jumbo frames.
Without using jumbo frames, the maximum Ethernet frame size is 1518 bytes, which
includes 46 bytes used for headers. This means that the maximum size for the data
packages that the Ranger can send is 1472 bytes, which should also be the maximum
value for the Max package size parameter in the Ethernet Configuration of the Ranger
when not using jumbo frames.
When using jumbo frames the Ranger unit can support up to 4054 bytes in each data
package, which corresponds to 4100 bytes per Ethernet frame.
Symptoms of Possible Problem
Receive Buffers
Symptoms of too low setting: Multiple consecutive packets are lost, e.g. 31 consecu-
tive packets are lost.
Symptoms of too high setting: Use of memory increases.
Jumbo Frames
Symptoms of too low setting: The Ranger will use a smaller frame size, which implies
higher CPU load on the PC.
Symptoms of too high setting: If you use a switch, which is unable to support Jumbo
Frames, connected between the Ranger and the PC, it is impossible to receive stream-
ing data from the Ranger.
TCP/IP settings
IP Address
In the recommended configuration the PC uses IP address 192.168.0.x, where x is
1 – 10.
Net mask
In the recommended configuration the PC uses net mask 255.255.255.0
