In this series of posts, we will present you some Use Cases of ELIOS
software.
The first an simplest Use Case of ELIOS is to wirelessly control an ArtNet
node using a tablet PC and a WiFi router (or access point).

What do you need :
- a tablet PC running Windows or Linux with Java and ELIOS installed (We use
SmartQ7 because it's really cheap, but if you prefer something more
user friendly and with Windows, have a look at EviGroup
Paddle.) ;
- a Wifi router or access point (We use TRENDnet TEW-654TR because it is really small and easy to
carry.) ;
- an ArtNet node (We use Enttec ODE because it's the cheaper and the most commonly
used.).
How does it work :
- The tablet (or computer) is connected to the router by Wifi.
- The router is connected to the ArtNet node using a simple Ethernet
cable.
- ELIOS directly sends ArtNet to the node via Wifi and Ethernet.
- The node emits DMX to control lighting equipments.
Advantages of this solution :
- You have a minimal set of devices. It's really easy to set up the system
each time you arrive in a new place.
Configuration points :
- configure your router with a Wifi network giving IP in 2.x.x.x or 10.x.x.x
with a subnet mask of 255.0.0.0 (needed by Artnet Protocol
Specification) ;
- configure your node to have an IP in the same network than router (2.x.x.x
or 10.x.x.x), to listen on the first universe and subnet and to output
DMX ;
- configure the tablet to join the Wifi network of your router ;
- configure ELIOS to broadcast ArtNet on the same network (2.x.x.x or
10.x.x.x) and to send ArtNet on the first universe and subnet.
It's the setup we use when we work because it is very simple to install and
really helpful. In our own case, our lighting board has a DMX input so we can
plug node output directly into it and have the two systems working at the same
time.
