Special Note: Line Termination.
When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
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.

Termination reduces signal errors and
avoids signal transmission problems
and interference. It is always advisable
to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.

5-Pin XLR DMX Connectors.
Some manufactures use 5-pin XLR
connectors for DATA transmission in place of 3-pin. 5-pin XLR fixtures
may be implemented in a 3-pin XLR DMX line. When inserting stan-
dard 5-pin XLR connectors in to a 3-pin line a cable adaptor must be
used, these adaptors are readily available at most electric stores. The
chart below details a proper cable conversion.

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:
Set DMX address 7:
Dip-switches # 1 = 1
Dip-switches # 1 = 1
2 = 2
3 = 4
= 7
Data Cable (DMX Cable) Requirements (For DMX and Master/Slave
Operation):
The Emerald Scan™ can be controlled via DMX-512 pro-
tocol. The Emerald Scan™ is a three channel DMX unit. The DMX
address is set on the side panel of the Emerald Scan.™ 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 use standard two conductor shielded cable (This cable may
be purchased 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.
Notice:
Be sure to follow figures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con-
nect the cable’s shield conductor to the ground lug or allow the shield
conductor to come in contact with the XLR’s outer casing. Grounding
the shield could cause a short circuit and erratic behavior.
