Lamp Replacement:
Caution! Never attempt to
change the lamp
while the fixture is plugged in.
Always disconnect the main power and
allow
the
unit
ample
time
to
cool
before
attempting
to
replace
the
lamp. Lamp replacement has been made simple by incorporating the
use of a flip-up front cover that is retained by thumb screws.
1.
Be sure to follow the proper handling procedures that deal
with halogen lamps.
2.
Remove the thumb screw on the top/rear of the unit that holds the
lamp socket assembly cover in place.
3.
After removing the thumb screw
, slide out the cove from the rear of
the unit to expose the lamp socket assembly.
4.
Carefully remove the old lamp and discard it in the trash.
5.
Replace the lamp with an exact match and reassemble in reverse
order
.
Notice:
Be sure to follow fi
gures 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
.

Special Note: Line T
ermination.
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 (DA
T
A
+ and
DA
T
A
-).
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
.

Te
rmination 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 DA
T
A
transmission in place of 3-pin. 5-pin XLR fi
xtures
may be implemented in a 3-pin XLR DMX line. When inserting standard
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.

below details a proper cable conversion.
