7. If the frame rate is unstable, if the image displays artifacts, or if you do not see an image at all,
the bandwidth used by the camera may be too high. To decrease the bandwidth used by the
camera carry out some adjustments as indicated below. For more detailed information, see the
Installation and Setup Guide for Cameras Used with Basler pylon for Windows (AW000611)
and the aviator GigE User’s Manual (AW000976).
a. Make sure the network adapter is properly configured:
If you use an Intel PRO network adapter, make sure the Jumbo Frames (or Jumbo
Packets) parameter is set to its maximum value. Make also sure the Receive
Descriptors parameter is set to its maximum value, the Interrupt Moderation Rate
parameter is set to Extreme, and the Speed and Duplex Mode parameter is set to Auto
Detect.
If you use a different network adapter, make sure the Jumbo Frames (or Jumbo
Packets) parameter is set to its maximum value. If no Jumbo Frames parameter is
present, select the parameter which relates to frame size and set it to its maximum value,
which is typically 1.5 kB. Also see whether parameters are available that allow setting the
number of receive descriptors and the number of CPU interrupts. The related parameter
names may differ from the ones used for the Intel adapters. Also, the way of setting the
parameters may be different. You may, e.g., have to use one parameter to set a low
number for the interrupt moderation and use a different parameter to enable the interrupt
moderation.
b. Set the camera’s network related parameters using the pylon Viewer:
Make sure the User Level is set to Expert or higher.
In the Image Format Controls group: Select an 8 bit pixel data format (i.e. Mono 8 or
Bayer GB 8) for efficient bandwidth use.
In the Transport Layer group: Set the Packet Size parameter to the maximum value
previously set for the network adapter and increase the value of the Inter-packet Delay
