6. ADDRESS
Set the DMX start address.
The DMX start address can be assigned from 001 to 512 and is common
to both DMX inputs.
When DMX MODE is set for DMX A+B operation, each of the DMX inputs can be
assigned to a separate DMX start address. The DMX inputs are merged and DMX-B
is offset by the number of DMX-A channels.
Press EXECUTE to enter the menu.
DMXA>001

7. DMX MODE
Configure the mode of the on-board DMX protocol manager.
There are five different mode settings for the DMX protocol manager.
Priority A (PTY A) and Priority B (PTY B) modes are intended for the implementation
of a backup DMX source. Priority A (PTY A) sets the DMX A input as the priority, and
ignores the DMX B input when the DMX A input is active. Priority B (PTY B) sets the
DMX B input as the priority, and ignores the DMX A input when the DMX B input is
active.
Merge (MERGE) mode combines both DMX inputs with highest-takes-precedence
(HTP) operation. Merge mode allows for simultaneous DMX control of the dimmers
from both inputs, and is the default for the system.
Dual Universe DMX (DMX A+B) mode provides a method to combine two universes
of DMX within one system. It permits two independent DMX sources to be active on
the DMX inputs, with each having a separate DMX start address. The DMX inputs are
merged and DMX-B is offset by the number of DMX-A channels programmed via the
ADDRESS menu (see ADDRESS - above for further details). This feature is typically
used when a system is at the end of one DMX universe (DMX-A) and the beginning of
another (DMX-B).
Two Room (2 ROOM) mode enables the room (A or B) assignment for each of the
dimmer outputs via the 2 RM SET menu.
PTY A
Press EXECUTE to toggle into Priority A (PTY A) mode.
PTY B
Press EXECUTE to toggle into Priority B (PTY B) mode.

2 ROOM

Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
NOTE: DMX O/P must be set to OFFSET mode for this menu to function.
