Configure the Network Interface Card

When the eGrabber driver is installed, the filter driver is enabled by default. In an operational environment, we recommend to keep the filter driver enabled. Check that the filter driver is enabled in your NIC properties, as shown on the screenshot below.

The filter driver operates directly with the NIC driver to intercept and handle the stream packets. It then sends these priority stream data directly to the application buffer, bypassing the system network IP stack.

For test purposes, you can disable the filter driver in the NIC properties.

In the Properties dialog box, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

With DHCP Server

●

Select Obtain an IP address automatically and click OK to validate.

Without DHCP server

1.

Select Use the following IP address and define the IP address settings, for example as follows:

□

IP address : 192.168.XXX.2, with XXX in the range [0-255].

□

Subnet mask : 255.255.255.0.

□

Default gateway remains empty.

If you use a multi-port NIC to connect to multiple cameras point-to-point, each point-to-point wire is considered as a separate LAN, you should define fixed NIC addresses and subnets for each port so that they do not collide, for example 192.168.100.2, 192.168.101.2, 192.168.102.2, etc.

2.

Click Advanced and set the metric to 1001 This value is provided for reference. in the IP Settings tab, if it is relevant to help keep unrelated traffic out of the GEV network:

3.

Click OK twice to validate and come back to the Properties dialog box.

Enable the Jumbo Packet settings allows you to transfer and receive larger streaming packets and reduce processing overhead.

Make sure that you enable the jumbo packets on the camera side (see Set packet size to maximum), and that other possible devices in the network between the camera and the host computer have jumbo frames enabled with the same MTU.

The Receive Buffers setting allows you to define how much system memory is dedicated to store received packets. Increasing the buffers helps improve the reliability of the network traffic, but consumes system memory.

The Interrupt Moderation settings allow you to define how often the adapter interrupts the system to handle the incoming (and outgoing) packets.

With GigE Vision cameras, it is more appropriate to set the highest level for interrupt moderation rate. This means that the NIC does not interrupt the processes, which reduces the CPU utilization. Instead the NIC driver actively decides when to check and handle the received packets.
