5.1 DMX Address Allocation [ADDR] 

Sets the DMX512 addresses for Redback's 
dimmers. 
Selecting this menu option displays the current 
DMX address of the first dimmer: 

D M X   1  

If dimmer addresses have been allocated from 
the Soft Patch [

SOFTP

] option of the Advanced 

Menus the display reads: 

P A T C H D  

Allocating an address from this menu overrides 
the addresses set from the Soft Patch menu.  
Levels set by DMX512 control are combined on 
a highest-takes-precedence basis with levels 
from the internal scene memories, the internal 
chaser and the optional MIDI interface. 
In Basic operating mode, the dimmers are 
automatically allocated sequential addresses 
following the start address. (eg. If the start 
address is set to 4, then dimmer 1 will be 
allocated a DMX address of 4, dimmer 2 will be 
allocated an address of 5, dimmer 3 will be 
allocated an address of 6, etc). 
 
This menu provides two methods for allocating 
the DMX address of the dimmers. 

5.1.1 Direct DMX address 

Direct DMX mode address allows the address of 
the first Redback dimmer to be set to any slot in 
the 512 slot DMX universe where all dimmers 
can be allocated a valid address (Range 1-501).

5.1.2 Bank address 

Bank mode allocates fixed blocks of addresses 
to the dimmers (see table). Selecting bank 1 
allocates DMX addresses 1-12 to the Redback, 
selecting bank 2 allocates DMX addresses 13-
24, etc. (Range 1-42).

5.2 MIDI Address Allocation [MIDI] 

Sets the MIDI addresses for controlling 
Redback's dimmers. 
Dimmers are controlled by Note-On, Note-Off 
and Velocity messages for a block of six 
adjacent MIDI Notes starting from the Channel 
and Note set from this menu.  
Levels set by MIDI control are combined on a 
highest-takes-precedence basis with levels from 
DMX512, the internal scene memories and the 
internal chaser. 
Selecting this menu displays the current MIDI 
Channel controlling the Redback dimmer or the 
current MIDI Note controlling dimmer 1.

5.3 Scene Setting [SCENE] 

Activates and sets a single static scene for 
situations where a control system is not 
available. 
Levels set in this scene are combined on a 
highest-takes-precedence basis with levels from 
the advanced scene memories, DMX512 
control, the internal chaser and the optional MIDI 
interface.
