I added a Multicast socket to my RCM3900 application, using IP 239.255.255.255.  I have a total of 4 UDP sockets open, 3 are opened with an REMIP and Port of -1, and one is opened with the Multicast IP and port 2100. And Max UDP Buffers is set to 5.
 

 After boot-up, the first UDP datagram to the module is not responded to. It doesn't matter if the datagram was a broadcast or a multicast. The first one is not responded to. After the first one, then it starts responding to both broadcasts and multicasts.  
 

 Is there something else I need to do to get that first datagram to work?
 

 I'm using DC 9.62.
