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 page 21 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.
MERGE
Press EXECUTE to toggle into Merge (MERGE) mode.
DMX A+B
Press EXECUTE to toggle into Dual Universe DMX (DMX A+B) mode.
2 ROOM
Press EXECUTE to toggle into Two Room (2 ROOM) mode.
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.
8. 2 RM SET
Set the two room assignment for each of the dimmer outputs.
This menu is used to assign each of the 96 dimmer outputs to room “A” or room “B”.
Dimmer outputs assigned to room “A” are controlled via the DMX-A input. Dimmer
outputs assigned to room “B” are controlled via the DMX-B input. This creates
separation within the dimmer rack and makes a single dimmer rack function as
though it is two independent dimmer racks. When used in conjunction with the DC
PATCH menu, the dimmer rack can be configured for sequential DMX control of two
rooms, even if the dimmer room assignments are not sequential.
DMX MODE must be set for 2 ROOM operation for this menu to function.
Press EXECUTE to enter the menu and activate 2 RM SET mode.
DIM 01 A
Displays the dimmer (DIM) output (01) and the room assignment (A).
DIM 96 A
Press MENU ( ) to select a different dimmer output from 01 to 96.
DIM 96 B
Press EXECUTE to toggle the room assignment from A to B.
Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
NOTE: Scene mode (SCENESET) will only activate/control dimmers assigned to
room “A”.
NOTE: DMX O/P must be set to OFFSET mode for this menu to function.
