2. Functional overview

LED-Warrior04 is a point-of-load regulator for

LED lighting applications. It offers multiple

options for lighting control. Direct control of the

four channels via I2C, DALI, DMX512, or

wireless is possible as well as autonomous

operation with settings preprogrammed via I2C,

including dynamic light scenarios.

3.1 Pin Description

Vin

Supply voltage input. Apply a DC voltage of 7V to

32V here. The input is protected with a fuse.

GND

Ground reference.

DMX+/DMX-

RS485 DMX connection, connect direct to the

DMX bus. Close jumper for bus termination.

I2C

SDA, SCL lines of the I2C interface.

+5V can supply power to add on modules like the

wireless module. Do not connect an external power

supply here!

DALI

The DALI physical bus interface module can be

placed on this header

Ch1, Ch2, Ch3, Ch4

Outputs to the LED strings. The negative pins are

not identical with ground. Do not connect pins of

two outputs together!

LED-Warrior04 4. Connecting the LEDs The maximum number of LEDs that can be driven by LED-Warrior04 depends on the supply voltage and the combined forward voltage of the LEDs. Input voltage needs to be about 2.5V higher than the total forward voltage of the LED string for proper operation. Connect the LED strings between the + and outputs for each channel. 4.1 EMC LED-Warrior04 has been designed to produce a minimal level of RF emissions.

LED-Warrior04 This command resets the LW04 to the same status as a power up does, it can not be combined with any write commands. 5.1.11 Register 15: Sequence Table Writing Sequence mode allows the LED-Warrior04 to autonomously perform dynamic lighting scenarios. This can be used to generate a power on fading, continous changing light situations, flashing, color changing, or any other lighting applications where a dynamic lighting without a external controller driving it is required.

LED-Warrior04 for each other at the end of their sequence iteration to continue together. Repeat contains the number of iterations for the sequence for the corresponding channel. $00 means the sequence will repeat infinitely. Length sets the number of data sets for each channel. Data sets are stored consecutively in the table, starting with those for channel 0. If there are 0 data sets for a channel it takes up no space in the table.
