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
1.2 Features
· All models powered by PoE (Power over Ethernet) · DIN rail models can also be powered from a 9-24v DC supply · Portable model can also be powered from USC-C · Individually isolated DMX ports · Each port can be individually configured to output any DMX Universe · Each port can be individually configured as an Input or Output · Each port configured as an Input can be set to generate sACN or ArtNet · Each port can be individually configured with RDM enabled or disabled · Each port can be labelled for greater clarity in more complex networks · Status LEDs provide instant confirmation of port activity · HTP (Highest Takes Precedence) merge per port · Configurable via HOUSTON X or ArtNet · Remote software upgrade via ethernet · Fast boot time < 1.5s · DHCP or static IP address modes · LSC 2-year parts and labour warranty · CE (European) and RCM (Australian) approved · Designed and manufactured in Australia by LSC

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.

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.

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.

NEXEN Outdoor IP65 · Port A ­ Output, sACN universe 1, RDM enabled · Port B ­ Output, sACN universe 2, RDM enabled
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.

5.10 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.

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. info@lsccontrol.com.au
