User Manual
1 Product Description
1.1 Overview
The NEXEN family is a range of Ethernet/DMX convertors providing reliable
conversion of protocols of the entertainment industry including Art-Net, sACN,
DMX512-A, RDM and ArtRDM. See section 1.3 for a list of supported protocols.
DMX512 control devices (such as lighting controllers) can send lighting data
over an Ethernet network to connected NEXEN nodes. The NEXEN nodes extract the
DMX512 data and send it to connected devices such as intelligent lighting
fixtures, LEDs and dimmers, etcetera. Conversely, DMX512 data connected to the
NEXEN can be converted to ethernet protocols.
Four models of NEXEN are available, two DIN rail mount models and two portable
models. On all models, each port is completely electrically isolated from the
input and all other ports, ensuring that voltage differences and noise will
not compromise your installation.
LSC’s free software product, HOUSTON X, is used to configure and monitor
NEXEN. HOUSTON X also allows the NEXEN software to be updated via RDM.
Therefore, once a NEXEN is installed, all operations can be performed remotely
and there is no need to access the product again.
RDM (Remote Device Management) is an extension to the existing DMX standard
and allows controllers to configure and monitor DMX based products. NEXEN
supports RDM but also can individually disable RDM on any of its ports. This
feature is provided because while many devices now offer RDM compatibility,
there are still products available that do not perform correctly when RDM data
is present, causing the DMX network to flicker or jam. Incompatible RDM
devices will operate correctly if connected to a port(s) with RDM disabled.
RDM can be used successfully on the remaining ports. See section 5.6.4

3 Power Supply
3.1 NEXEN DIN Power Supply
There are two possible power connections for DIN models. Both PoE and DC power
can be connected simultaneously without damaging the NEXEN.
· PoE (Power over Ethernet), PD Class 3. PoE delivers power and data over a
single CAT5/6 network cable. Connect the ETHERNET port to a suitable PoE
network switch to provide power (and data) to the NEXEN.
· A 9-24Volt DC power supply connected to the push-fit terminals observing the
correct polarity as labelled below the connector. See section 4.2 for wire
sizes. LSC recommends using a power supply of at least 10 watts for reliable
long term operation.
3.2 NEXEN Portable Power Supply
There are two possible power connections for the portable model. Only one type
of power is required.
· PoE (Power over Ethernet). PD Class 3. PoE delivers power and data over a
single CAT5/6 network cable. Connect the ETHERNET port to a suitable PoE
network switch to provide power (and data) to the NEXEN.
· USB-C. Connect a power supply that can supply at least 10 watts. Both PoE
and USB-C power can be connected simultaneously without damaging the NEXEN.
3.3 NEXEN Portable IP65 Power Supply
The portable IP65 model is powered by PoE (Power over Ethernet), PD Class 3.
PoE delivers power and data over a single CAT5/6 network cable. Connect the
ETHERNET port to a suitable PoE network switch to provide power (and data) to
the NEXEN.
4 DMX Connections
4.1 Cable Types
LSC recommends using Beldon 9842 (or equivalent). Cat 5 UTP (Unshielded
Twisted Pair) and STP (Shielded Twisted Pair) cable is acceptable. Never use
audio cable. The data cable must conform to the EIA485 cable requirements by
providing the following specifications:
· Low capacitance · One or more twisted pairs · Foil and braid shielded ·
Impedance of 85-150 ohms, nominally 120 ohms · 22AWG gauge for continuous
lengths over 300 metres In all cases, the end of the DMX line must be
terminated (120 ) to prevent the signal reflecting back up the line and
causing possible errors.

NEXEN Ethernet/DMX Node
4.2 DIN DMX Push-Fit Terminals
User Manual
The following cables are suitable for use with the push-fit terminals: ·
2.5mm² stranded wire · 4.0mm² solid wire
Stripping length is 8mm. Insert a small screwdriver into the slot adjacent to
the cable hole. This releases the spring inside the connector. Insert the
cable into the round hole then remove the screwdriver. Solid wires or wires
fitted with ferrules can often be pushed directly into the connector without
the use of the screwdriver. When connecting multiple cables to a single
terminal the wires must be twisted together to ensure a good connection to
both legs. Non-insulated bootlace ferrules can also be used for stranded
cables. Ferrules are not recommended for solid cables. Insulated bootlace
ferrules can also be used allowing stranded cables to be easily inserted
without the need of a tool to actuate the spring release. The maximum ferrule
outer diameter is 4mm.

5 NEXEN Configuration / HOUSTON X
5.1 Overview
NEXEN is configured using HOUSTON X, LSC’s remote configuration and monitoring
software. HOUSTON X is only required for configuration and (optionally)
monitoring of NEXEN.
Note: The descriptions in this manual refer to HOUSTON X version 1.07 or
later.
Hint: HOUSTON X also works with other LSC products such as APS, GEN VI, MDR-
DIN, LEDCV4, UNITOUR, UNITY and Mantra Mini.
5.2 HOUSTON X Download
The HOUSTON X software runs on Windows computers (MAC is a future release).
HOUSTON X is available for free download from the LSC website. Open your
browser then navigate to www.lsccontrol.com.au then click “Products” then
“Control” then “Houston X”. At the bottom of the screen click “Downloads” then
click on the “Installer for Windows”.
The software will download, however your operating system might warn you that
“HoustonX Installer is not commonly downloaded”. If this message appears,
hover your mouse over this message and 3 dots will appear. Click on the dots
then click “Keep”. When the next warning appears click “Show more” then click
“Keep anyway”.
The downloaded file has the name “HoustonXInstaller-vx.xx.exe where x.xx is
the version number. Open the file by clicking on it.
You might be advised that “Windows protected your PC”. Click “More Info” then
click “Run Anyway”. The “Houston X Setup Wizard” opens. Click “Next” then
follow the prompts to install the software answering “Yes” to any permission
requests. Houston X will be installed in a folder named Program
Files/LSC/Houston X.
5.3 Network Connections
The computer running HOUSTON X and all NEXENs should be connected a managed
network switch. Connect the NEXEN’s “ETHERNET” port to the switch.
Hint: When choosing a network switch, LSC recommends the use of “NETGEAR AV
Line” switches. They provide a preconfigured “Lighting” profile that you can
apply to the switch so that it easily connects with sACN(sACN) and Art-Net
devices.
Hint: If there is only one NEXEN in use, it can be connected directly to the
HX computer without a switch.
To run the program double click “HoustonX.exe”.
The NEXEN is set in the factory to DHCP (Dynamic Host Configuration Protocol).
This means that it will be automatically issued with an IP address by the DHCP
server on the network.
Page 12
NEXEN Ethernet/DMX Node
User Manual
Most managed switched include a DHCP server. You can set NEXEN to a static IP.
See section 5.8.
Hint: If NEXEN is set to DCHP, it will look for a DHCP server when it starts.
If you apply power to NEXEN and the ethernet switch at the same time, NEXEN
may boot up before the ethernet switch is transmitting the DHCP data. Modern
ethernet switches can take 90-120 seconds to boot up. NEXEN waits 10 seconds
for a response. If there is no response, it times-out and sets an automatic IP
address (169.x.y.z). This is as per the DHCP standard. Windows and Mac
computers do the same thing. However, LSC products resend the DHCP request
every 10 seconds. If a DHCP server comes online later, NEXEN will then
automatically change to a DHCP assigned IP address. This feature applies to
all LSC products with internal ethernet.

Click to select that protocol and universe.
Click OK to apply the selected protocol and
universe.
If the NEXEN is not connected to an active network you can still manually
select the protocol and universe as described in the following sections.
5.6.6 Protocol Click on each ports “PROTOCOL” box to reveal a drop-down box
that offers the available protocols for that port.
· Off. The port does not process sACN or Art-Net. The port still passes RDM
(if RDM is set to ON as described in section 5.6.4).
· sACN. When the port is set to OUTPUT mode, it generates DMX from the sACN
data received on the Ethernet port or from a DMX port that is configured as an
“Input” and set to sACN. See also “Universe” below. If multiple sACN sources
with the same universe and priority level are received they will be merged on
a HTP (Highest Takes Precedence) basis. See section 5.6.8 for more details on
“sACN priority”.
When the port is set to INPUT mode, it generates sACN from the DMX input on
that port and outputs it on the Ethernet port. Any other port set to output
DMX from the same sACN universe will also output that DMX. See also “Universe”
below.
· Art-Net. When the port is set to OUTPUT mode, it generates DMX from the Art-
Net data received on the Ethernet port or from a DMX port that is configured
as an “Input” and set to Art-Net. See also “Universe” below.
When the port is set to INPUT mode, it generates the Art-Net data from the DMX
input on that port and outputs it on the Ethernet port. Any other port set to
output DMX from the same Art-Net universe will also output that DMX. See also
“Universe” below.
Click on the required choice then press Enter
5.6.7 Universe The DMX Universe that is output or input on each port can be
independently set. Click on each ports “Universe” cell then type in the
required universe number then press Enter. See also “Available Universes”
above.

User Manual
5.6.8 ArtNet Merging
If a NEXEN sees two Art-Net sources sending the same universe, it does an HTP
(Highest Takes precedence) merge. For example, if one source has channel 1 at
70% and another source has channel 1 at 75%, the DMX output on channel 1 will
be 75%.
5.6.9 sACN Priority / Merging
The sACN standard has two methods to deal with multiple sources, Priority and
Merge. · sACN Transmit Priority Every sACN source can assign a priority to its
sACN signal. If a DMX port on a NEXEN has its “Mode” set as a DMX “Input” and
its “Protocol” is set to sACN, then it becomes a sACN source and hence you can
set its “Priority” level. The range is 0 to 200 and the default level is 100.
· sACN Receive Priority If a NEXEN receives more than one sACN signal (on the
selected universe) it will only respond to the signal with the highest
priority setting. If that source disappears, the NEXEN will wait for 10
seconds and then change to the source with the next highest priority level. If
a new source appears with a higher priority level than the current source,
then the NEXEN will immediately switch to the new source. Normally, priority
is applied per universe (all 512 channels) but there is also an unratified
“priority per channel” format for sACN where each channel can have a different
priority. The NEXEN fully supports this “priority per channel” format for any
port set to an “Output” but does not support it for ports set as an Input. ·
sACN Merge If two or more sACN sources have the same priority then NEXEN will
perform an HTP (Highest Takes precedence) merge per channel.

5.7.3 Restrict RDM IP Address
HOUSTON X uses RDM (Reverse Device Management) to control connected devices,
however other controllers on the network can also send RDM commands to control
the same devices which might not be desirable. You can restrict control of a
NEXEN so that it can only be controlled by the IP address of the computer
running HOUSTON X. Click COG , Restrict RDM IP address, then enter the IP
address of the computer that is running HOUSTON X.
Enter the IP address of the computer that is
running HOUSTON X.
Click OK. Now only this computer running HOUSTON X can control this NEXEN. 5.8
IP Address As mentioned in section 5.3, NEXEN is set in the factory to DHCP
(Dynamic Host Configuration Protocol). This means that it will be
automatically issued with an IP address by the DHCP server on the network. To
set a static IP address, double click on the IP address number.

5.9 Software Update
LSC Control Systems Pty Ltd has a corporate policy of continuous improvement,
covering areas such as product design and documentation. To achieve this goal,
we undertake to release software updates for all products on a regular basis.
To update the software, download the latest software for the NEXEN from the
LSC website, www.lsccontrol.com.au. Download the software and save it to a
known location on your computer. The file name will be in the format,
NEXENDin_vx.xxx.upd where xx.xxx is the version number.
Open HOUSON X and click on the NEXEN tab.
The “APP VER” cell shows you the current version number of the NEXEN software.
To update the NEXEN software, double click on the version number of the NEXEN
that you wish to update.

Follow the on-screen instructions and the NEXEN software will be updated.
5.10 Use NEXEN to inject RDM into DMX. HOUSTON X uses ArtRDM to communicate
with LSC devices (such as GenVI dimmers or APS power switches). Most (but not
all) manufacturers of Ethernet (ArtNet or sACN) to DMX nodes support RDM
communication over Ethernet by using the ArtRDM protocol provided by ArtNet.
If your installation uses nodes that do not provide ArtRDM, HOUSTON X cannot
communicate, monitor, or control any LSC devices that are connected to those
nodes.
Page 20
NEXEN Ethernet/DMX Node

In the following example, the node does not support ArtRDM so it does not forward the RDM data from HOUSTON X in its DMX output to the APS Power Switches so HOUSTON X cannot communicate with them.

NEXEN inserts RDM.
The NEXEN takes the DMX output from the node and adds the RDM data from the
NEXENs ethernet port then outputs the combined DMX/RDM to the connected
devices. It also takes the returned RDM data from the connected devices and
outputs this back to HOUSTON X. This allows HOUSTON X to communicate with the
LSC devices whilst still allowing the devices to be controlled by the DMX from
the non ArtRDM compliant node.

User Manual
This configuration keeps the monitoring network traffic isolated from the
lighting control network traffic. It allows the HOUSTON X computer to be
located on an office network or directly connected to the NEXEN.
The procedure to set up RDM injection using a NEXEN is……
· NEXEN Input. Connect the DMX output from the non-compliant node to a Port of
the NEXEN. Set this port as an INPUT, the protocol to ArtNet or sACN and
choose a universe number. The protocol and universe number that you choose is
irrelevant, provided that the Universe is not already in use on the same
network to which HOUSTON X might be connected.
· NEXEN Output. Connect a Port of the NEXEN to the DMX input of the DMX
controlled equipment. Set this port as an OUTPUT and the protocol and the
universe number to the same as used on the input port.
It is also possible to connect the HOUSTON X computer and the NEXEN to the lighting control network. Ensure that the protocol and universe selected on the NEXEN are not in use on the control network.

6 Terminology
6.1 DMX512A
DMX512A (commonly called DMX) is the industry standard for the transmission of
digital control signals between lighting equipment. It utilises just a single
pair of wires on which is transmitted the level information for the control of
up to 512 DMX slots. As the DMX512 signal contains the level information for
all slots, each piece of equipment needs to be able to read the level(s) of
the slots(s) that apply only to that piece of equipment. To enable this, each
piece of DMX512 receiving equipment is fitted with an address switch or
screen. This address is set to the slot number to which the equipment is to
respond.
6.2 DMX Universes
If more than 512 DMX slots are required, then more DMX outputs are required.
The slot numbers on each DMX output are always 1 to 512. To differentiate
between each DMX output, they are called Universe1, Universe 2, etcetera.
6.3 RDM
RDM stands for Remote Device Management. It is an “extension” to DMX. Since
the inception of DMX, it has always been a `one way’ control system. Data only
ever flows in one direction, from the lighting controller outwards to whatever
it may be connected to. The controller has no idea what it is connected to, or
even if what it’s connected to is working, switched on, or even there at all.
RDM changes all that allowing the equipment to answer back!
An RDM enabled moving light, for example, can tell you many useful things
about its operation. The DMX address it is set to, the operating mode it is
in, whether its pan or tilt is inverted and how many hours since the lamp was
last changed.
But RDM can do more than that. It is not limited to just reporting back, it
can change things as well. As its name suggests, it can remotely manage your
device.
RDM has been designed to work with existing DMX systems. It does this by
interleaving its messages with the regular DMX signal over the same wires.
There is no need to change any of your cables but because RDM messages now go
in two directions, any in-line DMX processing you have needs to be changed for
new RDM hardware. This will most commonly mean that DMX splitters and buffers
will need to be upgraded to RDM capable devices.
6.4 ArtNet
ArtNet (designed by and copyright, Artistic Licence Holdings Ltd) is a
streaming protocol to transport multiple DMX universes over a single Ethernet
cable/network. NEXEN supports Art-Net v4. There are 128 Nets (0-127) each with
256 Universes divided into 16 Subnets (0-15), each containing 16 Universes
(0-15).
6.5 ArtRdm
ArtRdm is a protocol that allows RDM (Remote Device Management) to be
transmitted via ArtNet.
6.6 sACN
Streaming ACN (sACN) is an informal name for the E1.31 streaming protocol to
transport multiple DMX universes over a single cat 5 Ethernet cable/network.

7 Trouble shooting
When choosing a network switch, LSC recommends the use of “NETGEAR AV Line”
switches. They provide a preconfigured “Lighting” profile that you can apply
to the switch so that it easily connects with sACN(sACN) and Art-Net devices.
If HOUSTON X cannot find your NEXEN it might be looking at the wrong port
number. See section 5.4.1 to resolve this problem.
Devices connected to a NEXEN DMX port are not appearing on HOUSTON X. Ensure
that the NEXEN DMX port is set to OUTPUT and the ports RDM is ON.
If the NEXEN fails to operate, the POWER LED (for the connected power source)
will light RED. Contact LSC or your LSC agent for service.
