CP4N: sACN traffic goes to control subnet, I need it on LAN port...


 

Hi!

I use the CP4 control port for NVX network. On the lan port there is a DMX unit i need to control with sACN.
My problem is that the sACN traffic is going to the CP4 control port and not to the lan port.
sACN is multicast and that may be the reason why it is routed to the control port (NVX multicast network port).

Do anyone know if it is possible to route the UDP socket in the simpl+ file to the lan port and not control port?
The multicast address is?239.255.0.44:5568

Erik :)


 

All of the sACN projects I've done have used a node with a non-multicast address in the standard class C, B, or A IP address ranges.?
While the traffic may be sent multicast, the node you're controlling shouldn't solely have a multicast IP address. There should be a "control" IP address, similar to NVX.
We have used the DMXKing units as well as Chauvet DMX-AN and the Net-X. All three have standard class C, B, or A IP addresses.?
The CP4 should be smart enough to route traffic to the correct port based on the IP range. So if your LAN port is 192.168.x.x and your control subnet is 172.16.x.x, if the node's control IP is on 192.168.x.x, it should send from the correct port.?

Maybe I'm missing something major here.?


 

Erik, curious if you got things worked out??
I was informed of the exact opposite problem at a project site today where the CP4N was sending sACN on the LAN port and we need it on the Control Subnet port.?
Didn't know how you ended up proceeding on this project.?
