KNX Gateway DMX-Web K.DMXGW.01
Intended use
– Unidirectional data exchange between KNX and a DMX system
– Mounting on DIN rail to EN 60715
Product characteristics
The Gateway has two operating modes:
Operating mode "DMX master"
– Translation of KNX values into DMX data bytes
– Cyclic transmission of KNX values to the assigned DMX channels in the DMX bus with
250 kBit/s
– Control of RGB or RGBW luminaires via special logic modules
– Mapping of the functions switching (1-bit), relative dimming (4-bit) and absolute
dimming (1-byte)
– Master dimming object (1-byte) for channel groups
Operating mode "DMX slave"
– Reception of data bytes from the DMX bus
– Translation of the DMX data bytes into KNX values
Assignment between DMX channels and KNX group addresses is performed using a
table stored in the gateway. Assignment of the KNX group addresses and configuration of
the operating mode are performed using the Windows software DMX-Gate4 (or higher).
The current software as well as a detailed description of the commissioning can always
be found in the Internet.

4 Information for electrically skilled persons
4.1 Fitting and electrical connection
DANGER!
Electrical shock on contact with live parts in the installation environment.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live parts
in the working environment.
General notes
Use data cable with 120 ohm characteristic impedance (e.g. CAT 5, 6, 7 network cable) for the
DMX bus.
Use a common wire pair each for the signals DMX In + / - and DMX Out + / -.
Do not use the terminal pairs DMX In and DMX Out to loop through a DMX signal. The terminal
pairs are only used individually depending on the operating mode.
Do not wire DMX bus in a star configuration.
Only use power supply units that supply secure extra low voltage SELV for power supply.
Connecting the device – operating mode "DMX master"
Figure3
In the operating mode "DMX master" the gateway functions as a DMX data generator. The ter-
minals DMX Out and GND are used for connection to the DMX bus.
Connect a maximum of 32 devices per gateway.
Only a single data generator is permitted in a DMX system. In order to combine the gate-
way with an additional DMX data generator (e.g. a DMX lighting console), a so-called
"DMX merger" is required.
￭ Connect DMX bus to the terminals DMX Out + and DMX Out - (2) and GND (3).
￭ Connect KNX bus to the KNX terminals (7).

￭ Connect external power supply to one of the two terminal pairs AC/DC 24 V (11).
Connecting the device – operating mode "DMX slave"
Figure4
In the operating mode "DMX slave" the gateway functions as a DMX receiver. The terminals
DMX In and GND are used for connection to the DMX bus. When additional receivers are con-
nected to the DMX bus the DMX cable has to be continued over terminals DMX In and GND
(Figure 4). Do not use DMX Out terminals.
￭ Connect DMX bus to the terminals DMX In + and DMX In - (2) and GND (3).
￭ Connect KNX bus to the KNX terminals (7).
￭ Connect external power supply to one of the two terminal pairs AC/DC 24 V (11).
Connecting the terminating resistor
(operating mode "DMX slave" only)
Figure5
A DMX bus should be provided with a terminating resistor at its last device. Otherwise, reflex-
ions at the end of the cable can lead to signal distortions.
4 / 7
82575434 06.02.2020

KNX Gateway DMX-Web K.DMXGW.01
Terminate cables only with the supplied terminating resistor (11).
Only provide a DMX bus with a terminating resistor if the gateway is the last device in the
DMX bus line.
There may never be more than one terminating resistor on a DMX bus.
￭ Connect terminating resistor (11) to terminals DMX In + und DMX In - parallel to the DMX
bus line.
Looping through external power supply
Both terminal pairs (9) can be used for looping through the external power supply (Figure 6).
The total power consumption of all looped-through loads must not exceed 1.5 A.

4.2 Commissioning
Commissioning
The gateway is commissioned via a Windows PC and the DMX-Gate4 software (or higher). The
current software including the related documentation can always be found in the Internet at
www.insta.de.
The IP interface serves to connect the PC to the gateway. A crosslink-network cable might have
to be used for the direct connection.
￭ Connect PC to the gateway via IP connection.
￭ Switch on PC.
￭ Switch on external power supply.
￭ Wait until the status LED Power/Error flashes orange.
￭ Start DMX-Gate4 software and follow the instructions on the screen.
Load physical address
The physical address is loaded with ETS or with DMX-Gate4.
When assigning the physical address with ETS, proceed as follows:
￭ Switch on the KNX bus voltage.
￭ Press the programming button (8) (Figure 1).
￭ Download physical address to the device with the ETS.
The KNX group addresses are assigned by means of the software DMX-Gate4. A plug-in
ensures the synchronisation of the group addresses with the associated ETS project
(from ETS4 onwards). Alternatively, use a dummy application for creating the filter tables
correctly.
The assignment of the physical address with DMX-Gate4 is described in the software
documentation.
