Ground return for 12V input 

 
Each of these will be described in more detail below. 

There are two motors; one for the upper shutter and one for the lower. Both are 
wired identically.  
 
Make sure that the Upper terminals are connected to the Upper motor, and the 
Lower terminals are connected to the Lower motor. Otherwise the shutters will 
not sequence properly and will bind.  
 

 

Motor Driver Board 

 
The Open/Close wires go from the Dome Controller board to the Motor Driver 
board.  The wires may be connected in parallel with the manual switch at the 
Motor Driver board.  
 
A ground wire must also be connected between the boards. This provides a 
return path for the control lines. This wire can be connected to any of the 
terminals marked GND.  
 
Note that, if for some reason the dome rotates in the wrong direction, the Open 
and Close wires can be swapped.
