Dmx Data Connection - Techni-Lux DL-LEDPAR1C36O/B User Manual

DMX Data Connection

This fixture uses 3 pin XLR type connectors and shielded twisted pair cable approved for
EIA-422/EIA485 use. Fixtures are connected in Daisy Chain topography: Connection is
made from the controller to the DMX-IN of the first light, then from the DMX-OUT to the
DMX-IN of the next light and so on. Only one data source can be on a chain and no
branching is allowed. The physical order in which the fixtures are connected is not
important, use the most convenient.
XLR Connector - Plug:
Data Terminator
A Data Terminator can be connected to the DMX-OUT of the last fixture
to reduce the effects of signal noise; it is not required for all
installations. To make a Terminator, connect a 120-ohm ¼ watt resistor
across pin 2, Data Negative (S-) and pin 3, Data positive (S+). A
qualified technician can determine if a Data Terminator is needed.
Adapter 5-to-3 pin
Systems using 5 pin DMX interfaces can be accommodated by purchasing 3-to-5 pin
adapters or building adapter cables. Numbers designating each pin can be found on
connectors. Converting between the two XLR types is done in a pin-to-pin fashion.
Connect the shields to pin 1, then connect pin 2 to pin 2 and pin 3 to pin 3, regardless of
either connector's gender or pin count. No connection is made to Pins 4 & 5.
