Address and Configure the Fixtures
Make sure the power is ON before addressing and configuring fixtures.
When in DMX mode, each ColorBlast TRX fixture uses a set of sequential DMX
addresses. A ColorBlast TRX fixture uses 3, 5, 6, or 10 DMX channels depending on
color control mode (3-channel or 5-channel DMX input) and fixture resolution (8-bit
or 16-bit). In 8-bit mode, each LED channel uses one DMX address, while in 16-bit
mode, each LED channel uses two DMX addresses, as follows:
RGB3 / RGB5 (3-channel RGB DMX input)
1
8-Bit Mode
Red
1
16-Bit Mode
Red Coarse
NORM (5-channel RGBAW DMX input)
1
8-Bit Mode
Red
1
16-Bit Mode
Red Coarse
To address a ColorBlast TRX fixture, you set its DMX starting address. Sequential
DMX addresses are automatically assigned to the fixture beginning with the starting
DMX address. For instance, if you set a fixture to RGB3 mode, 8-bit operation, and
starting DMX address 73, the fixture is automatically assigned three DMX addresses,
73 – 75. If you set a fixture to RGBAW (NORM) mode, 16-bit operation, and
starting DMX address 400, the fixture is automatically assigned ten DMX addresses,
400 – 409.
For lighting designs where fixtures work in unison, all fixtures can be assigned the
same starting DMX address. For light show designs that show different colors on
different fixtures simultaneously, you must assign starting DMX addresses to your
fixtures such that the DMX addresses assigned to each fixture are unique and do not
overlap.
• You can manually set the color control mode, fixture resolution, and starting
DMX address of a ColorBlast TRX fixture using the onboard menus. See "Using
the ColorBlast TRX Onboard Menus" below for details.
• The PDS-750 TRX power / data supply from City Theatrical Inc. offers
convenient, automatic addressing appropriate for many ColorBlast TRX
installations. Using onboard controls, you can set a starting DMX address to
automatically assign sequential DMX addresses to installed fixtures, or you can
set starting DMX addresses individually per power port. If your fixtures were
previously addressed for use in other installations, you can easily reset them using
the power / data supply's built-in controls. Refer to the PDS-750 TRX Operator's
Manual for details.
• You can connect a computer via SmartJack Pro to the DMX IN port on the
PDS-750 TRX power / data supply, and address and configure your fixtures using
QuickPlay Pro addressing and configuration software. For details, see "Addressing
and Configuring ColorBlast TRX with QuickPlay Pro" below.

In 16-bit operation, two DMX channels
E
are assigned to each LED channel, one for
coarse control and one for fine control. The
coarse channel allows values in multiples
of 256, while the fine channel adds 256
additional values to each coarse channel
value, resulting in a total of 65,536
individual steps or settings (256 x 256).
