Data Cable Requirements (For DMX and Master/Slave Opera-
tion):
The Mighty Scan™ can be controlled via DMX-512 protocol.
The DMX address is set using the dip-switches on the rear panel of the
Mighty Scan™. Your unit excepts 3-pin XLR connector for data input
and data output (Figure 5). When using a DMX controller with 5-Pin
XLR output jacks or when linking from a DMX fix-
ture with 5-Pin XLR jack to the Mighty Scan™, be
sure to follow the pin conversion chart on page
12. 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 6 and 7 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.

Termination reduces signal errors and

to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.

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 connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number ZDMX/T) will decrease the possibilities of erratic
behavior.

Since the unit automatically has a DMX address of 1, dip switch 2 has
a value of 3, and dip switch 5 has a value of 17, the combination cre-
ates a DMX value of 21.

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.
Important Notice:
This fixture follows the European DMX
addressing standard.
When operating this fixture with a standard
DMX-512 controller, the fixture’s DMX value automatically starts on
one (1) with all the dip switches in the off position. For example: To
get a DMX value of one (1) you would have to flip dip switch one (1)
to the on position. In the case of the Mighty Scan™ however, dip
switch one (1) on, would give the Mighty Scan™ a DMX value of two
(2). To get a value of one (1), all the dip switches would have to be in
the off position. To get a DMX value of two (2) set the DMX value to
one (1), for three (3) set the DMX value for two.
