fixtures will be slaved together and respond to the same data. Because all fixtures see the
same data, fixtures may be set to any address without concern for the order they are connected
by the DMX cables.
Note:
For DMX to operate on this unit it must be set to SLAVE mode.
DMX Data Connection
This fixture uses 5 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.
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+). Whether it is a 5 pin XLR or 3 pin XLR connector
(shown on right) does not matter, the pin numbers remain the
same. 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.
