Assigning DMX Address: Each dipswitch has a preset value. A spe-
cific DMX address is set by combining the dipswitches that sum your
desired value. For example: To achieve a DMX address of 7, combine
dipswitches 1, 2, and 3. Since dipswitch 1 has a value of 1, dipswitch
2 has a value of 2, and dipswitch 3 has a value of 4, the combination
of the three create a DMX value of 7. (See example below).
Set DMX address 1:

Data Cable (DMX Cable) Requirements (For DMX and Master/Slave
Operation): The Emerald Sky™ can be controlled via DMX-512 proto-
col. The Emerald Sky™ is a two channel DMX unit. The DMX address
is set on the rear panel of the Emerald Sky. ™ Your unit and your DMX
controller require a standard 3-pin XLR connector for data input and
data output (Figure 1). If you are making your own cables, be sure to

chased at almost all pro sound and lighting stores). Your cables should
be made with a male and female XLR connector on either end of the
cable. Also remember that DMX cable must be daisy chained and can
not be split.

behavior. A terminator is a 90-120 ohm 1/4 watt resistor which is con-
nected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This unit is inserted in the female XLR socket of the last unit
in your daisy chain to terminate the line. Using a cable terminator (ADJ
part number Z-DMX/T) will decrease the possibilities of erratic behav-
ior.
