After trying to help another member today to get LSP to talk to a DR-4. I’m at a loss. The da_e131 program will light up lights connected to one of Rays 3ch controllers without a problem, The DMX channels that light it up are 50,51,52 .Which is what the address of the controller is set to.So that cant be the issue. Working on just the first output on the dr-4, The config settings set to output 1 = universe 101 LSP: Controller tab In LSP we have added a DR-4 from the controller menu and it is configured as: Zone/network =101 Logical channels =3 Controller type= RGB lightcontroller Controller Protocol= E1.31 DMX over Ethernet Channels Tab: Numbered from ch 50 onwards. Configure Channels Output: Universe =101 (active) Start ch = 50 Size = 3 Destination =Multicast Local Area Connection. All that gives us nothing when we use test controller hardware test . Am I missing another setting somewhere as mine works like this.
