For your own safety, please read this user manual and warnings carefully
before installation.
Description
The DMX-Universal-Demux is equipped for universal applications with several
operation modes. 8 outputs release a signal depending on the DMX-input signal and
according to the operation mode.
8 outputs with open-collector driver
There are 8 outputs with open collector output driver for controlling external devices.
Voltages from 12V up to 24V
The DMX-Universal-Demux operates with supply voltages from 12V up to 24V.

Available are the operation modes Threshold / Binär / PWM / Servo / Strobo.
Controllable via DMX
The DMX-Universal-Demux is controlled by DMX and uses 1 or 8 DMX channels
depending on the operating mode.
DMX FAIL-Function
An adjustable DMX FAIL function offers the option to hold the current state (HOLD)
or to change to a predefined value in case of DMX signal failure.
RDM support
The DMX-Universal-DMX allows the configuration via RDM or DMX.
LED status display
The LED status display shows the DMX reception.
DIN rail housing available

Addressing
The starting address is adjustable via a DIP-Switch.
Switch 1 has the valency 2
0
(=1), switch 2 has the valency 2
1
(=2) and so on… finally
switch 9 has the valency 2
8
(=256).
The sum of the values of the switches showing ON, represents the starting address.

LED-Display
The LED is a multifunctional display.
In the normal operation mode, the LED lights non-stop. In this case the device is
working. If the LED is permanently dark, there is no DMX512-input-signal.
Furthermore, the LED signals the operation status. In this case, the LED light up in
short pitches and then turns into off modus. The number of flashing signals is equal
to the number of the error status:

Operation mode
The operation mode is selectable via a jumper. It is important to place the jumper in
accordance to the following drawings to ensure a clean function.
It is not possible to combine the modes.
With switch 10 the output signal can be inverted in any operating mode.
Hysteresis 127/128 (no jumper placed)
In threshold mode (hysteresis 127/128) 8 successive
DMX channels are received.
The belonging output will be set on OFF if the
received value is between 0 and 127 and set on ON
if the received value is between 128 and 255.
Thereby output 1 is according to the first and output 8 is according to the last
channel.
This mode allows switching external load relays.

Binary-Output (only jumper J1 is placed)
In the mode Binary-Output (Binary (8-Bit)) only one
DMX channel is needed. The received value will be
binary outputted at the output. Thereby output 1 is
according to the first and output 8 is according to the
last bit.

Strobe-Control (only jumper J2 is placed)
The DMX-Universal-Demux outputted 8 controlling
signals for stroboscope in the Strobe-Control.
Thereby each output will be triggered with one DMX-
Channel.
The DMX-Value assignment is as follows:
DMX
Channel
DMX
Value Function
1...8
0-10 Stroboscope off
11-249 Flashing speed slow →fast
250-255
Synchron flash
Only one time the output will be triggered. Switch
back and forth between the DMX-Value 0 and
255 to get a synchronized flashing.

PWM-Output (only jumper J3 is placed)
In the PWM-Mode 8 successive DMX channels are
outputted as PWM-Signal. Depending on the DMX-
Value the PWM-signal will be generated in a range
of 0-100%.
T ON T OFF
DMX LEVEL: 64
T ON T OFF
DMX LEVEL: 192
The PWM-Frequency is ca. 175 Hz.
Servo-Control (only jumper J4 is placed)
The DMX-Universal-Demux receives 8 successive
DMX-Channels and outputted a signal for triggering
customary servos. Thereby each output will be used to
trigger one Servo.
For operating with Servos is a 5V power supply necessary, in the rule.
Please note, for the most Servos an additional resistor is needed which must
be connected between the data line and +5V.

In this mode the outputs switch on for 1 second as soon as the DMX value is 170 or
higher. After that the DMX value must fall below 85 again to trigger a switching pulse
again.

RDM (ab Hardware V1.3)
RDM is the short form for Remote Device Management.
As soon as the device is within the system, device-dependent settings can occur
remotely via RDM command due to the uniquely assigned UID. A direct access to the
device is not necessary.
If the DMX start address is set via RDM, all address switches at the DMX-
Universal-Demux must be set to OFF ! A DMX start address set by the
address switches is always prior !
This device supports the following RDM commands:

Factory Reset
Before running the Factory Reset, read all steps carefully.
To reset the DMX-Universal-Demux to delivery state, proceed as follows:
-Turn off device (disconnect power supply !)
-Set DIP switch 1 up to 10 to ON
-Turn on device (connect power supply)
-The LED lights up 20x during ca. 3 seconds
While the LED lights up set DIP switch 10 to OFF
-Now, the Factory Reset is executed
The LED lights up with error code 4
-Turn off device (disconnect power supply !)
-Now, the device can be used
If a Factory Reset is needed again, this procedure can be repeated at any
time.
