Issue Details

I am having the issue to communicate with my hardware using UDP communication via Ethernet cable connected to the PXIe controller. When a GIGE camera is connected to my Ethernet interface module, the multicast UDP data cannot be sent. When I remove the camera, the UDP data can be sent to my hardware. 

Solution

You need to specify which Network Interface Card's (NIC) address to be used for multicast at the UDP Multicast Write-Only Open Function. The Ethernet port is also considered as network interface, therefore it is causing the confusion for the UDP to communicate.
