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.
Contact your authorized dealer or ETC for ordering information (
),
or purchase an XLR DMX terminator from the ETC Online Shop (
).
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 DMX start address on the user interface, which is located on the rear of the fixture.
See
.
Example:
The Cyberlight LED requires 40 channels of control. If you set the DMX
starting address of the first fixture to 1, you could set the second fixture to 41 (40+1),
the third to 81 (40+41), and so on.
