DMX Settings

DIP Switch Settings:
1= DMX base address (1)   6= DMX base address (32)
2= DMX base address (2)   7= DMX base address (64)
3= DMX base address (4)   8= DMX base address (128)
4= DMX base address (8)   9= DMX base address (256)
5= DMX base address (16) 10= Terminate (on/off)

DMX Addressing (Firmware version 1.1):
Address 0 – Sleep mode (device can safely remain on DMX bus) Address 1 to 508 – Normal DMX function
Address 509 – Steps through each output channel sequentially Address 510 – Cross fade pattern, R-G-B-R-G-B-R….
Address 511 – All channels on full (lamp test)
