How to turn off IMAQdx periodically sending a "Discovery Ping" to 255.255.255.255?

[GuenterMueller]

IMAQdx seems to search for GigE cameras by periodically (about every second) sending a "Discovery Ping" to 255.255.255.255.
As my vision system does not use any GigE camera (only FireWire) I would like to get rid of these "Discovery Pings".
Is there a recommended way to accomplish this?

Hi Guenter,

On Windows there is not currently a simple way to disable GigE Vision support in the installer. However, you can disable the automatic discovery mechanism with the following registry key:

You should be able to save the following as a .reg file and import it:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\niimaqdxk\Parameters]

"DiscoveryTimeout"=dword:00000000

Thanks Eric. I will try this tomorrow. BTW: Do I loose GigE support this way? Or is it just the support to discover "yet unknown" GigE devices? Guenter

You would lose automatic discovery of GigE Vision cameras. You can still manually discover cameras by running the Discover Ethernet Cameras function/VI.

Ok, Eric. I see, that it works. (No need to wait until tomorrow.)

Thanks, Guenter

I have a couple of questions in regard to this.

If use the registry key as described is there a way to manually detect the camera when you are using the Measurement and Automation Explorer?

Is there anyway to restrict the discovery ping to a specific network card? We typically install a second NIC card and use non-routable IP addresses for that NIC and camera and it would be nice to limit the discovery ping to that card.

Hi Eric,

i cant see the link

As this is an old thread I don't know if you can still rely on this information.

However, if a registry key doesn't exist, you can create it ...
