Automatic DMX Addressing
When automatically assigning DMX start channels to fixtures on a link, the
ColorPower supply allocates the DMX addresses in the order of each fixture’s unit
number (specified by the DIP switch setting on each fixture) (see Figure 2-5).
Addresses are assigned sequentially starting with the address immediately following
that of the ColorPower supply. Each Dichroic Theater product attached to the
ColorPower is assigned an address according to its module address and fixture type.
ColorCommand fixtures require four channels, and ColorMerge fixtures require
three channels.
After selecting AUTO, the attached fixture types and their addresses are stored in an
on-board EEPROM. Thereafter ColorPower acquires its addressing information
from this EEPROM. If fixtures are added to the link after selecting AUTO, they will
be assigned an invalid address. If fixtures are removed from the link, they will be
ignored. In either event, removal or addition of fixtures will not change addressing,
and thus will not change your show. The auto address mode will not allow multiple
fixtures to share the same DMX address.
To Address a fixture by automatically assigning the start channel:
1. Using ColorPower’s menu system (see Figure 2-3 on page 2-6), press and hold
the <Menu> button until
dMX
appears on the LED display.
2. Press <Enter>.
3. Using the <Up> and <Down> arrow buttons, scroll to the
MOdE
menu and
press the <Enter> button to select.
AUTO
will appear on the display as the first
option.
4. To select, press and hold the <Enter> button until
dONE
displays.
IMPORTANT: You must complete this procedure after all fixtures have been
added to the fixture link. ColorPower only assigns start
channels automatically after all steps in this procedure are
completed. In other words, the start channels assigned using
