User Manual

DMX-LED-Dimmer 4 2

Description

The DMX-LED-Dimmer 4 is designed to control RGB, RGBW or SINGLE COLOR

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

(=1), switch 2 the valence 2

(=2) etc. until switch 9 has

the valence 2

(=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:

Description

1 No DMX There is no DMX-Signal at the dimmer

2 Address error Check if a valid DMX starting address is adjusted via

switches 1-9

3 DMX-Signal error An invalid DMX-Entry signal is detected. Invert the

signal lines at pin 2 and 3 or use a twisted pair wire.

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 1 (R)

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:

Color changes 2:

Color changes 3:

Color changes 4:

Color changes 5:

Color changes 6:

Color changes 7:

Color changes 8:

Switch 8 = ON = slow color changes

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 HardwareHardware 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.
