Detailed Programming
of System Configuration Menu Items
NOTE: When the DPC-12 or DPC-24 is powered up, the menus are “LOCKED!!” with access
only to the basic system configuration menus, which includes setting the DMX start
address as well as enabling or disabling the end-of-line DMX termination. The menus
need to be “UNLOCKED” to access the advanced system configuration menus. To
toggle between “LOCKED!!” and “UNLOCKED” press and hold down the EXECUTE
and then ESCAPE switches at the same time for 4-5 seconds.
The sequence of the following system configuration menu items appear as the MENU DOWN ( )
switch is pressed. Pressing the MENU UP ( ) switch will sequence the system configuration
menu items in the opposite order. Pressing and holding either of the MENU UP/DOWN ( )
switches will speed up the scroll rate, which can be helpful to speed up the configuration time.
Basic Menus
1. 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 Displays the current DMX start address for both DMX inputs.
DMXA>512 Press MENU ( ) to modify and select the desired DMX start address.
DMXA>001 Press both MENU ( ) simultaneously to toggle to DMX start address 001.
DMXA>025 Press EXECUTE to save the selected DMX start address.

#CHA=>01 *Press EXECUTE to advance to select the number of DMX-A channels.
#CHA=>24 *Press MENU ( ) to modify the number of DMX-A channels from 01 to 24.
Press ESCAPE to exit the menu and save the selected DMX start address.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
NOTE: * DMX MODE must be set for DMX A+B operation to access this feature.
