2.
Press the <Enter> button to enter the “ADDR” menu.
3.
Using the <Up> and <Down> arrow buttons, scroll to the desired DMX 
start channel and press the <Enter> button to select the desired DMX 
start channel.  
Note
You must assign a unique fixture address to each Studio 
Spot 250 or Studio Color 250 fixture that you wish to 
respond independently to controller commands.
Determining the Unique Fixture Number
The fixture number is a number you assign that represents each 
unique fixture’s channel range in the DMX 512 link.  If you are using 
one DMX link to control fixtures which all use the same number of DMX 
channels (as recommended), you can assign fixture numbers in 
ascending order (see Table 2-3).
To assign a unique fixture number to your fixture:
1.
Press and hold the <Menu> button until “ADDR” appears on the LED 
display.
2.
Press the <Enter> button to enter the “ADDR” menu.
3.
Using the <Up> and <Down> arrow buttons, scroll to the desired 
fixture number and press the <Enter> button.
Note
You must assign a unique fixture address to each 
Technobeam fixture that you wish to respond 
independently to controller commands.
Wasted DMX Channels
If you mix different types of devices (which use different numbers of 
channel ranges) on the same DMX link and assign fixture numbers 
(instead of DMX start channels) to these devices, you would waste DMX 
channels.
