LED-Stripes with 12V, 24V or 48V.
It has 4 PWM-Outputs, which are controllable independently via DMX.
Alternatively internal color gradients can be called up without any external control.

Addressing
The DMX-Start address is adjustable via switches 1 up to 9.
Switch 1 has the valence 2
0
(=1), switch 2 the valence 2
1
(=2) etc. until switch 9 has
the valence 2
8
(=256). In total switches showing ON correlate with the starting
address.
Switch 10 is reserved for the StandAlone-Function and must show OFF during the
DMX-Operation.
LED-Display
The integrated LED is a multifunctional-display.
During the normal DMX-Operation the LED flashes permanent. In this case the
device is working.
Furthermore the LED shows the event. In this case the LED lights in short pitches
and then turns into the off mode for a longer period. The number of flashing impulses
corresponds with the error status:

Behavior at DMX-Fail
If a DMX fail (DMX-Fail) occurs the DMX-LED-Dimmer 4 is able to hold the LED-
Outputs on the last value or can shut off or turn on all LED-Outputs.
The behavior in case of a DMX-Fail is adjustable via jumper:
ALL ON: ALL OFF: HOLD:

DMX-Master-Dimmer
The DMX-LED-Dimmer 4 has several Master-Dimmer. These can be activated via
jumper 1 and 2 as following:
Master dimmer
That DMX-Channel which is set with the start address is used for the master dimmer
for all 4 outputs. The DMX-Address assignment is as follows:
System-Masterdimmer
The Master-Dimmers value is according to DMX-Channel 1, which is used as Master-
Dimmer for all 4 outputs. The DMX-Start address shows the DMX-Channel on which
the DMX-Values start. The assignment is as follows:
Master

OUT 2 (G)
OUT 3 (B)
OUT 4 (W)

Set operation modes
The DMX-LED-Dimmer 4 has several operation modes adjustable via
jumper 3 and 4:
8-Bit with LookUp-Tables
Each output is controlled with one DMX-Channel (8-Bit).
Thereby the configured LookUp-Tables are considered.
4KHz HighFrequency
The DMX-LED-Dimmer 4 uses in this operation mode a 4kHz PWM- Output
frequency.
This mode is for usage in accordance with video recording useful, e.g. in TV-Studios.
16-Bit
Each output is controlled with two DMX-Channel (2x8Bit = 16-Bit).
The second DMX-Channel is for fine-tuning.
The several operation modes can’t be combined !
The Masterdimmer-Option can be set independently of the selected operating
mode.

Call internal color changes
The internal color changes can be called by change switch 10 on ON.
The DMX-LED-Dimmer 4 provides a slow mode for slow color changes. This mode
can be activated by change switch 8 on ON.
Now, you can select the color change programs via switches 1, 2 and 3.
The following color changes are selectable:
Color changes 1:

Configuration the LookUp-Table
The DMX-LED-Dimmer 4 has one LookUp-Table per output.
The received DMX-Channel has values from 0 up to 255. However the DMX-LED-
Dimmer 4 output driver provides 65536 steps (16 Bit) which will be assigned to the
DMX-Values via the LookUp-Table.
So it‘s possible to effect in the lower brightness range little brightness changes with
small steps. However in the upper brightness range it’s possible to program bigger
steps.
A Standard USB-Mini-B Connection cable is necessary to transfer the Look-Up
Table to the DMX-LED-Dimmer 4 as well as a USB-Connection to the PC.
Via the DMX-Configurator the LookUp-Tables can be defined. The DMX-Configurator
is available for free as download.
- Connect the DMX-LED-Dimmer 4 with a
standard USB-Mini-B connection cable to PC. As
shown in the picture on the right site, plug the
cable on the USB-Connection of the DMX-LED-
Dimmer 4.
- Install the USB-Driver if it is not available.
- Start the DMX-Configurator Software
(V2.3.9 or higher is needed)
- Generate a connection to DMX-LED-Dimmer 4
If no LookUp-Table is configured (delivery status) the output control occurs in-
line.
DMX-LED-Dimmer 4 10
- Open Hardware-Settings (menu HardwareHardware Settings)
For each output (OUT1-OUT4) a table with DMX-Values in the range of 0-
255 and the according output values (OUTPUT) is available.
A graphic presentation illustrates the output line.
- Configure the output line
- Check the output line by selecting the LookUp Test and move the slider.
The connected LED behaves according to the output line.
- Select WRITE TO DEVICE to transfer the table to the DMX-LED-Dimmer 4.
