Ethernet link between 2 DMX devices


In this setup, the related products will be used as input and output boxes . The  first  Luminex  device  will  convert  DMX  signal  to  ArtNet  protocol  in order  to  run  one  single  Ethernet  cable  instead  of  several  DMX  lines. However, please remember that Ethernet specification allows to use cables no longer than 100mbetween two active Ethernet devices.

Please notice that if you're not using  an Ethernet  switch to interconnect the 2 Ethernet devices, a crossover Ethernet cable will have to be used.
This kind of setup can be very useful for instance when you have to run your DMX signal through the existing network of a building or a venue. 

Input/output box as dual splitter

In this setup, the related products will be used as input/output boxes (see Illustration 8). The Luminex device is set to act as a dual splitter (1 input, 3 outputs on the same universe for each lighting desk).
The two lighting desks can run their dedicated DMX network on the same device. The node here can be compare to a Luminex 2.10 Splitter.

Automatic DMX switcher

This setup is inspired from a real installation; it perfectly shows the ability of Luminex products to answer to all kind of configuration.




The  aim  of  this  installation  is  to  provide  an  automatic  DMX  switcher between three small lighting desks and a main one;    Each small lighting desk  is  controlling  a  dedicated  zone,  and  the  main  desk  can  control  all zones.
The difficulty of the setup is that the main desk is not always connected, so  the  Luminex  device  has  to  switch  automatically  to  the  dedicated Lighting desk, for this to control its own zone. 
The aim was not to use a merging policy, but a  real  automatic switcher between DMX sources.
The main lighting desk is running one single universe, split on each zone through the Luminex devices outlets.
Of course, the main desk patch has been split on the three small lighting desks to avoid channel overlapping.
The  main  principe  of  this  auto  switching  is  to  use  the  builtin  backup feature of Luminex devices, base on ArtNet source IP addresses.
As the Luminex device use two IP addresses, it's easy to virtually use 2 different IP sources. In this case, the main desk is 2.0.0.2 and the small desks are 2.0.0.3.
The following screenshots show the   main configuration of the Ethernet DMX8 and the detailed configuration (see illustration 11) of one of the 3 outputs.
