                                                     Set Up

Operating Modes:

Stand-Alone Operation (Sound Active and Auto Program):

 

 

Sound Active:
1.  Put dipswitch #1 in the “On” position. The unit will react to the low  
 

frequencies of music via the microphone. 

2.  Dipswitch 3 will reverse the rotation.
Auto Program:
1.  To run the Auto Program, put dipswitches 1 & 2 in the “On” po-
 

sition. 

 

Dipswitch 3 will reverse the rotation.

 

Dipswitches 4, 5, & 6 will control the speed of rotation.  

2.  The optional UC3 Controller (not included) may be used to con- 
 

trol different functions including blackout. See the next page for 

 

UC3 controls.

Master-Slave Operation:

 

This function will allows you to link units together to run in a Master-
Slave mode. In Master-Slave operation one unit will act as the con-
trolling  unit  and  the  others  will  react  to  the  controlling  units  built-in 
programs. Any unit can act as a Master or as a Slave however, only 
one unit can be programmed to act as the “Master.” 
1.   Using standard XLR microphone cables, daisy chain your units  
 

together via the XLR connector on the rear of the units. Remem- 

 

ber the Male XLR connector is the input and the Female XLR    

 

connector is the output. For longer cable runs we suggest a    

 

terminator at the last fixture.

2.  Simply daisy chain the units together using XLR cables. 

3.  For the Master unit put dipswitch 1 in the “On” position, and all  
 

other dipswitches in the “Off” position. For the Slave units, put  

 

any dipswitch in the “On” position, except, the #1 dipswitch.  

 

The #1 dispswitch must stay in the “Off” position on all Slave  

 

units.

3.  The optional UC3 Controller (not included) may be used to con- 
 

trol different functions including blackout. See the next page for 

 

UC3 controls.

Universal  DMX  Control: 

This  function  allows  you  to  use  a  uni-

versal  DMX-512  controller  such  as  the  Elation

®

  DMX  Operator™  or 

 Jellydome   

                                                Operation

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 110-120 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  Z-DMX/T)  will  decrease  the  possibilities  of  erratic 
behavior.

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.
