The Ether-Lynx is a 1RU rack mount solution to the transfer of large
amounts of lighting data over a wide area. Ether-Lynx uses a 10BaseT
Ethernet link for this purpose.
Ether-Lynx can translate two DMX512 inputs into Ethernet and
simultaneously translate Ethernet into four DMX512 outputs.
DMX512
Inputs
The DMX512 inputs accepts all flavours of DMX (pre and post 1990
and DMX512-A). A receive data indicator is provided for each input.
The indicator illuminates when good DMX512 is detected.
The input is optically isolated from the output, chassis and mains
earth. This is of particular benefit in removing earth loop problems
in large installations and outdoor events.
The DMX512 input is not terminated, but connected to a passive loop
through connector. If the Loop Through facility is not required, a
terminator (Stock Code DMX-Term5) should be fitted.
Input connection is via a male 5 pin Neutrik XLR connector.
DMX512
Outputs
The DMX512 outputs comply with all revisions of the DMX512
standard and are optimised for DMX512-A.
The outputs are continuously refreshed irrelevant of whether input
data is available. The outputs are connected via 5 pin Neutrik female
XLR’s wired to the USITT standard.
Each output is provided with an indicator, the indicator illuminates to
show that changing data is being transmitted.
Outputs C & D are equipped with electronics for the RDM – Remote
Device Management standard. Units with a serial number 177 or
above use RDM draft V1.0. New updates for the Ether-Lynx can be
downloaded from www.ArtisticLicence.com and installed to an EtherLynx using the DMX-Workshop application.
The outputs are Ground Referenced (Pin 1 connects to chassis).

Art-Net
Ethernet
The Ethernet port connects via a screened Neutrik Ethercon
connection.
Network wiring may use either UTP or STP cable.
The screen connection of the Ethercon is connected to chassis and
mains earth via a 100 ohm resistor.
Power over Ethernet is neither supported nor connected.
Device
Operation
The Ether-Lynx is designed to transfer DMX512 data over a
network.
There are two main interconnection scenario’s:
1. Point to Point - In this scenario only two Ether-Lynx are used.
They can be connected together directly using a cross-over
Ethernet cable.
2. Network - In this scenario three or more Ether-Lynx are used.
The Ether-Lynxs are all individually connected to a standard data
hub using straight wired network cable.
Network
Sharing
The Art-Net protocol used by Ether-Lynx is based on the TCP/IP
protocol. This means that it will coexist on the same network as any
other standard Ethernet protocol. This is of particular benefit when
adding Ether-Lynx distribution into an existing site that already
contains a network.
However, some consideration must be given to the available
bandwidth of the network. Art-Net uses a compression algorithm
that ensures that the minimum bandwidth is used when DMX512
inputs are not changing. However, a fast changing DMX512 input will
use about 3% of the bandwidth available on 10BaseT.
The system installer must ensure that if a shared network is used,
enough bandwidth is available to ensure that the DMX512 data is not
delayed by heavy network traffic.
Network
Indicators
The Network Communication indicator is illuminated when Ether-Lynx
recognises valid Art-Net data from the network connection.

System
Setup
The entire system is setup with seven rotary controls on the front
panel. The controls consist of:
1. Sub-Net - This wheel selects one of the sixteen possible sub-nets
available in the Art-Net protocol. Two or more Ether-Lynx must
be set to the same subnet in order to communicate. The sub-net
can be considered as a ‘box address’.
2. Input Address - Each DMX512 input has an input address wheel.
This wheel selects one of the sixteen DMX universes available on
each subnet.
3. Output Address - Each DMX512 output has an output address
wheel. This wheel selects one of the sixteen DMX universes
available on each subnet.
DMX data is simply transferred from one Ether-Lynx to another by
setting the subnets to the same value and then matching the input
address to the output address.
The front panel controls can be set remotely using the network
administration software: DMX-Workshop. This program is free of
charge and can be downloaded from www.ArtisticLicence.com
When set remotely, the front panel controls are disabled. Any
attempt to adjust the controls will result in no action other than the
related indicator flashing.
Splitter
Operation
The output addresses can be set to identical values if required, to
produce identical DMX512 outputs both on the same Ether-Lynx or
across the network.

Clashing
Inputs
DMX512
Pin
Data
If the input address wheels are set to the same value, the DMX512
data received will be merged on a highest takes precedence (Htp)
basis.
The DMX512 input is connected to the male 5 pin XLR on the rear
panel.
Cable connection is as follows:

Ether-Lynx are connected using screened 8 pin RJ45 connectors.
When connecting two Ether-Lynx together, a simple cross-wired
cable can be used. To connect more that two Ether-Lynx together, an
Ethernet Data Hub will be required.

Power
Supply
Earthing
The internal power supply requires a 90-240V AC input with an earth
connection. The mains fuse should only be replaced with a 3.15A
Slow Blow.
The following table summarises the internal earth interconnection
and isolation:
Please note that we use the term Earth-Ground to avoid international
confusion. In Europe Earth-Ground is called Earth, in the USA EarthGround is called Ground.

Art-Net is a TCP/IP based Ethernet protocol developed by Artistic
Licence.
In an attempt to assist in standardisation, the Art-Net protocol has
been put into the public domain so that any other manufacturer may
freely use the protocol. The specification document can be

As the Ether-Lynx can be programmed to operate on non-standard IP
addresses, it is sometimes useful to override these settings.
To do this, set all of the front panel wheels to the ‘F’ setting. Cycle
the power. The Ether-Lynx will then respond on the standard ArtNet addresses as defined by JP9, JP10 above.
This operation is identical to closing JP7 and cycling the power, it
simply saves opening the case.
