LCD Display
The LCD display is capable of displaying 2 lines of 8 characters. A backlight automatically comes
on when activity is sensed. The LCD contrast can be easily adjusted for optimum viewing.
Refer to menu item “LCD VIEW” on page 22 for further details.
Programming Switches
The MENU UP/DOWN ( ) switches are used for navigating through the various system
configuration menu items. They also allow for programming of other specific parameters within
a selected menu. Pressing and holding either switch will speed up the scroll rate, which can be
helpful to speed up the configuration time.
The EXECUTE ( ) switch is normally used to select/enter a menu item, advance forward within
a selected menu item, or toggle between parameters within a selected menu item.
The ESCAPE ( ) switch is normally used to back up within a selected menu item one step at a
time or exit the menu completely.
The RESET switch has two purposes. First, it allows for quick exit from a menu item after a
programming change and automatically puts the system into normal run mode. Second, it provides
a soft reboot for the systems microcontroller.
The programming switches are backlit with blue LED’s. The LED’s automatically turn on when
activity is sensed. The LED intensity can be adjusted in the “LED INT” menu. Refer to page 24 for
further details.
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.
NOTE: A detailed procedure for programming all system configuration menu items can be found
on page 11 to 22.
12 or 24 Local Buttons/Switches
The 12 or 24 local buttons/switches (a.k.a. bump buttons) can be configured for two different
modes. They can either be configured as bump buttons or to activate scenes. Refer to menu item
“L-BUTTON” on page 17 for configuration details.
The local buttons are backlit with blue LED’s. The LED’s indicate the approximate control level for
each of the 12 or 24 dimmers. As the control level for a dimmer is increased, the intensity of the
LED increases.
For a 6 dimmer circuit CD80 pack, button 1 controls and indicates dimmer 1, button 3 controls
and indicates dimmer 2, button 5 controls and indicates dimmer 3, button 7 controls and indicates
dimmer 4, button 9 controls and indicates dimmer 5 and button 11 controls and indicates dimmer 6.
NOTE: To configure a DPC-12 for 6 PACK (6 dimmer circuit CD80 pack) operation,
select 6 PACK in the DEFAULTS menu..
