Figure 2.1: Visual Productions' RdmSplitter
The DIN Rail RdmSplitter from Visual Productions (See figure 2.1) helps tackle
those inconvenient limitations. The Splitter takes a DMX signal and sends it
out again on its 6 DMX output ports for scaling group topology. Each output
port is capable of driving 32 more devices. The Splitter can also function as a
signal booster as each port supports another 300 meter long connection.
The QuadCore has four DMX ports and is therefor able control 2,048 channels.
Each port can also be configured to become a DMX input allowing external
DMX data to be recorded or to use an external DMX source to trigger events
within the QuadCore.
2.2 Art-Net
The Art-Net protocol primarily transfers DMX-512 data over Ethernet. The
high bandwidth of an Ethernet connection allows Art-Net to transfer up to 256
universes.
The data sent out for Art-Net does put a certain load on the network, therefore
it is recommended to disable Art-Net when not in use.
Additional to transmitting DMX-512 data, Art-Net can also be used for trans-
ferring timecode information for equipment synchronisation.
Each QuadCore supports sending and receiving of 4 Art-Net universes as well
as receiving Art-Net timecode.
2.3 sACN
The streaming Architecture of Control Networks (sACN) protocol uses a method
of transporting DMX-512 information over TCP/IP networks. The protocol is
specified in the ANSI E1.31-2009 standard.
