1.1 DMX/RDM SPLITTER
MDR-DIN is a DINrail-mounted DMX/RDM data splitter.
Two models are available:
•DMX INPUT and 4 DMX outputs via push-fit terminals
•2 DMX IN/THRU RJ45 sockets and 4 DMX output RJ45 sockets
MDR-DIN supports RDM (Remote Device Management), see section 1.10.
MDR-DIN is powered from an external power source (9-24V DC, 5W).
1.2 INSTALLATION
1. Mount the unit on the DINrail.
2. Connect a suitable power source to the 9-24V DC push-fit terminals observing
the correct polarity. A minimum of 5W of power is required.
3. Connect the DMX512 cables…
Plug the DMX source cable into either
DMX IN/THRU connector.
Connect the DMX source cable
into the DMX INPUT terminals.
If this MDR-DIN splitter is the last device
at the end of the DMX512 input cable,
connect a 120 ohm resistor to the other
DMX IN/THRU connector. See section
1.7 for the pin-outs.
If the MDR splitter is not the last device
on the line, the other DMX IN/THRU
connector can be used to connect the
DMX to other equipment.
If this MDR-DIN splitter is the last
device at the end of the DMX512
input cable, connect a 120 ohm
resistor across the DMX INPUT
terminals.
If the MDR splitter is not the last
device on the line, the same DMX
INPUT terminals can be used to
connect the DMX to other
equipment in parallel.
Connect the DMX512 output cable(s) to
the DMX512 output connector(s).
Connect the DMX512 output
cable(s) to the DMX512 output
terminals.
1.3 RDM ENABLE
Some older DMX-controlled equipment is not compatible with RDM data and
could flash or flicker when RDM data is present. To overcome this problem, each
individual output port can have the RDM data turned off via the front-panel
switches.
1.4 OPERATION
•The DMX512 data LED flashes when DMX data is present
•The RDM data LED flashes when RDM data is present
•The Power LED is lit when power is present and flashes when an RDM Identify
request is received
