Operation of the Sensor
surfaceCONTROL 2500
6.4.3.3 Configuration
The network card settings should be adjusted to improve system performance when
using Gigabit Ethernet cameras. Goal of the optimization is to minimize CPU usage and
to avoid packet loss.
Adjust the network card settings according to the following table:
Property Value
Packet size/maximum transmission unit (MTU) 8228 bytes or greater
Interrupt moderation Enable
Interrupt moderation rate Extreme
Receive buffer Maximum value configurable
Transmit buffer 256 bytes
The naming and setting options can vary depending on the network card used.
Standard packet size
The standard packet size of the cameras is 8228 bytes. The network card in the PC must
support at least this packet size to make use of the full performance capability of the
cameras.
Enabling jumbo frames
For optimal performance of the two cameras, jumbo frames should be enabled on the
network card. Depending on the manufacturer and type of the network card, the setting
is referred to as “Jumbo Frames” or “Jumbo Packets”. If this setting cannot be found, the
network card does not support this feature and should not be used with the sensor.
Proceed as follows to enable the jumbo frames:
Locate the network card used for the camera in the device manager or in a compa-
rable setting of your operating system.
Go to the settings of the network card.
Select the Jumbo Packet entry and set the value to 9014 bytes.
Confirm the change with
OK.

After the change, an existing connection to the cameras is disconnected and re-
built.
6.5 Operating Information
6.5.1 Measuring Range
The measuring range of the sensors is factory-set. It is not possible to change the mea-
suring range by exchanging the lenses.
The area illuminated by the projector is relevant for the actual measuring range of the
sensor. The cameras are arranged in such a way that both cameras capture the area
illuminated by the projector within the complete measuring volume.
The measuring range in the Z-direction is trapezoidal due to the point-shaped light
source of the projector and the fan-out over the lens.
