ELC DT2210 User Manual
The ELC DT-2210 DMX / RDM splitter is a flexible DMX splitter with support for the
bidirectional
extension to the DMX protocol called Remote Device Management
(RDM).
Normal DMX cabling has to be done in daisy chain connection, meaning the DMX
connection goes from the DMX source (console) to the first device, then to the next
device, and so on. The last device will have to be equipped with a terminator plug.
A maximum of 32 DMX devices is allowed on a single line.
This is not an ideal cabling scheme. To use a more star-like approach, DMX splitters
are needed. A splitter has one input and multiple outputs. Each output regenerates
the signal, so each output is also a new DMX source. This is also called boosting.
With the new RDM specifications, DMX is extended with the ability for devices to
“talkback” to the source (console). This requires a special kind of splitter (or hub),
such as the ELC DT2210 or DT125. These splitters will reverse the communication
when required.
This product may only be used for
controlling dimmers and moving lights.
Using the product outside of these specifications
will remove all responsibility from the supplier.
The DT-2210 has 2 DMX inputs on the back of the device. Each input has its own
“thru”-connection (female XLR). This thru-connection is parallel wired to the input
and can be used to connect to another DMX device or a terminator plug. Both inputs
are galvanic isolated from the rest of the electronics.
The outputs on the DT-2210 are located on the front of the unit. The 10 front outputs
are grouped in pairs of 2 - each provided with a selector switch to choose either input
A or B. The outputs on the fully isolated (FI) version of the DT-2210 also have galvanic
isolation.
