Detailed Programming
of System Configuration Menu Items
NOTE: When the J-PACK Series dimmer pack 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.
