Hello everyone,
I have been using OLA for a year or so to build a Raspberrypi DMX Controller. I have managed to make it work for a single universe (only had a few fixtures <<512 channels) using an Enttec USB Pro dongle.
In order to improve my show, I am adding addressable LEDs (1080 RGB pixels). I bought the following Artnet node :
These 1080 pixels require 3240 channels or 7 universes to be carried over artnet. I thought this was something the ola artnet plugin could handle but I am slowly coming to the conclusion that I was wrong :
Both the folloing sources seem to indicate a limit at 4 universes per "Ola device".
Extract from the OLA plugin README :
This plugin creates a single device with four input and four output ports
and supports Art-Net, Art-Net 2 and Art-Net 3.
...
output_ports = 4
The number of output ports (Send Art-Net) to create. Only the first 4 will
appear in ArtPoll messages
...
Old convo from this mailing list :
Technically this thread is about the max nb of INPUT universes whie i'm interested in OUTPUT universes so... I don't know if it is relevant
However, I tried setting output_ports to 8 in the plugin .conf file, patching more universes using the ola.HTML web client and it seems to work. I can see the unis both in the html client & when running ola_dev_info :
however, running ola_dmxcosole -u 1/2/3/4
+ watching the result with a sniffer (artnetominator & wireshark) works just fine while
while ola_dmxcosole -u
5/6/7/8 sends absolutely nothing
Given the scarcity of the available documentation (that i have found at least) & my limited knowledge in networking & artnet, I am quite confused & would like to know for sure (before eventually looking for an other solution) :
Is there any way I can send more than 4 universes FROM my Pi (running OLAD + custom frame computing program) TO the BC-204 artnet NODE ?
Regards,
Pierre
