Ethernet Control and DMX Thru
You can use Ethernet control and DMX Thru. When a fixture is set up to receive Ethernet control
input, it automatically distributes DMX via the DMX Thru port. The DMX-512 signal is sent as a
single universe that corresponds to the universe of the fixture that is receiving Ethernet control.
Terminate DMX
Use a DMX terminator or install a resistor on the last fixture of the DMX control run to prevent
corruption (data reflection) of the digital control signal by electrical noise.
A DMX terminator is an XLR plug with a 120
Ω
resistor connected between pins 2 and 3 that can
be installed into the DMX output receptacle of the last fixture in the DMX control run. This plug
is available and sold separately. Contact your authorized dealer or ETC for ordering information
(
).
Set the DMX Start Address
Give each fixture a unique DMX starting address so that the correct fixture responds to the
control signals. This DMX start address is the channel number from which the fixture starts to
“listen” to the digital control information sent out from the control source.
Modify the fixture DMX start address on the user interface, located on the upper enclosure. See
.
Example:
The Lonestar has 48 channels. If you set the DMX starting address of the
first fixture to 1, you could set the second fixture to 49 (48+1), the third to 97 (48+49),
and so on.
Set the Control Input and Universe
For Ethernet control, you must configure the control input (Art-Net on IP2, Art-Net on IP10, or
sACN) and set a universe for each fixture. See
and
for details.
