Dear Sir/Madam,

My system has 4 ethernet network adapters and one digital I/O. I have connected 2 cameras of model DFK 33G618 and 2 cameras of model DFK 33G618 to 4 ethernet network adapters.But system got hanged. Can you please help me to solve this issue?

Thanks and Regards

Hello Vivek

"system got hanged" is not a suitable error message.

However: I guess around....
All network controllers and cameras run on DHCP. If so, then no operating system in the world (e.g. Windows, Linux, iOS) can differ between them and wont be able to find a network device.

Please use persistant IP addresses for cameras and network interface controllers (NIC):
nic 1: :
cam 1: :

nic 2: :
cam 2: :

nic 3: :
cam 3: :

nic 4: :
cam 4: :

Make sure, you do not give the same IP address to two network interface controllers, because Windows will fail and you will never be able to access the controller again. In this case, you must reinstall Windows, which is not really funny.

If you use this configuration, you must connect always the same camera to the same NIC. I found it helpful to mark the cameras and NICs with color points, so I know, which camera to connect into which NIC.

Hi Stefan,

Normally industrial PC has four PCI slots in its ****** board and we have fixed Digital I/O card in one slot and DLink Ethernet cards in remaining three slots. We have connected three cameras in Dlink Ethernet ports and we tried to start the inspection but cameras are got hanged. I have checked it if we are using three PCI slots in live then it is working. But If we are using four PCI slots in live then cameras got hanged.Please find the following system configuration and camera configuration:
Processor: Intel(R) core(TM) i7-4790 CPU @ 3.60 GHZ
Hard Disk: 500 GB
****** board #: AIMB-784
Advantec I/O Card (8 bit)
Operating System: Windows 7 Professional (32 bit)

Camera Details:
Brand Name: Imaging Source
Model #: DFK33G445 -> 2 no’s
Model #: DFK33G618 -> 2 no’s

We are giving persistant IP addresses for cameras and network interface controllers (NIC) as suggested you.

Thanks and Regards

Hello Vivek

Are there really PCI slots? Not PCIe? You may calculate the data rate you have and compare it to the 133MB/s that can be transferred by PCI.

You can calcultate width*height*frames_per_second per camera and sum the values. Then you know approximately the amount of data sent over the PCI bus.

I suggest to try lower frame rates. This reduce the amount of data per second.
