DMX Mode Selection
The FL-B Blaze fixture has internal jumpers which can be preset to operate the unit in one of four DMX
control modes. Minimal control mode allows control of fixture intensity, while full control mode allows control
over fixture intensity and effect motor speed. Depending on the fixture model, the unit may be set to use
from one to four DMX channels. The default setting for all FL-B Blaze fixtures is for four channel DMX
mode. The first two channels control the intensity of the red and amber LED emitters, with two additional
channels controlling the speed of the effect drive motors.
DMX Mode Confirmation
The selected DMX mode can be confirmed without opening the unit. When power is applied to the fixture in
DMX mode, the green “Power” indicator will light immediately, and the green “Sync” indicator will flash from
one to four times depending upon the DMX Mode setting. The number of flashes corresponds to the mode,
and to the number of DMX channels required to properly control the fixture. After displaying the DMX
mode, the “Sync” indicator will then go out in the absence of DMX data, or will illuminate steadily if good
DMX data is being received.
DMX Mode Selection
The DMX mode is selected by the position of internal jumpers J7 and J8, which are located on the DMX
Interface board inside the fixture. If necessary, these settings can be altered by opening the fixture to change
the jumper settings . The fixture should be disconnected from the DC power supply before opening the unit
housing to change any jumper setting. The jumper positions for the various settings are illustrated below.
