The default value for receive descriptors is 256. Set this to the maximum
available - typically 2048.
Save changes by clicking OK .
The NIC is now enabled to handle larger packets. This means that,
instead of sending image data from the camera in chunks of 1500 bytes
they can now come in chunks of 9014. That means about 6 times fewer
packets for each image.
Increasing the number of receive descriptors enables the NIC to handle
more packets at any one time. If the processor is busy when an image
arrives, the NIC may not be able to send on the data immediately but data
is still coming in from the camera. These receive descriptors buffer the
system against this. (It is almost essential when using a CMG50 camera).
Attaching and Configuring the Camera(s)
Once you have all this done you can connect your camera directly or plug
in a switch and then connect cameras to that. As they come out of the box
the cameras should now assign themselves addresses in the
192.168.254.x range. They are still receiving information about the
network from outside in order to make this choice. You can simplify things
still further by assigning each camera its own static address.
When you install Visionscape a couple of utilities are installed for you.
These can be found under the Start Menu in:
Start > All Programs > Microscan Visionscape > Tools > Diagnostics
