Supported Protocols
The Art SSC is fitted with several communication ports and supports various protocols. This
chapter describes these protocols.
DMX-512
Connect your lighting fixtures either to the DMX OUT A port or DMX OUT B. Use a 5-pin XLR cable
to connect the Art SSC's DMX OUT port to the first fixture, from then on daisy-chain to all other
fixtures.
3 Pin Adapter
If your cabling or fixtures are using a 3-pin XLR connector then you can
obtain - or create yourself - a 5-to-3-pin adapter.
For both 5-pin and 3-pin connectors the pin-out is:
1 = GND
2 = Data-
3 = Data+
(on the 5-pin XLR pin 4 & 5 are not connected)
Cable
Use a shielded twisted pair cable for DMX cabling. The cable should be terminated with an 120
Ohm resistor.
Overcoming DMX-512 Limitations
DMX-512 is a very successful protocol with, however, a few
limitations. The maximum number of attached devices is limited
to 32 and they all have to be connected in bus-topology having
one cable running via each device. Furthermore, a DMX cable
should not be longer than 300 meters.
The DMX Branch/4 from Elation Professional helps tackle those
inconvenient limitations of DMX-512. The Splitter takes a DMX
signal and sends it out again on its 4 DMX output ports allowing a star-topology for efficient cable
usage. 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.
RDM
RDM is a recent addition to the DMX-512 protocol. The DMX protocol was uni-directional. RDM
makes it bi-directional and allows for the controller to receive status information from the fixtures
and set properties like the fixture's starting address.
Both of the DMX outputs are RDM capable (the DMX input is not) and the RDM master
functionality for collecting all the information and setting all the parameters will be implemented via
an external software program (not available yet).
Art-Net
The Art-Net protocol primarily transfers DMX-512 data over Ethernet. The high bandwidth of a
