LM-3R
Ethernet to DMX converter
1. DESCRIPTION
LM-3R is an Ethernet to DMX converter. It has been designed to transport DMX through an Ethernet
network, and it has two operation modes: WORKNET (own protocol) and Art-Net.
LM-3R is a plug and play device, it does not need any network configuration. LM-3R is automatically
configured, which means that it obtains automatically an IP address 2.x.x.x and a Subnet Mask 255.0.0.0,
just as Art-Net protocol specifies. However, for advanced users, network configuration can be modified using
the web browser interface, as seen below in this document.
1.1 WORKNET MODE
In WORKNET mode LM-3R operates as the receiver of the DMX information sent by LM-3E (the transmitter).
So, in this mode, LM-3R always must be used in combination with one LM-3E, and both LM-3E and LM-3R
must be configured in the same group (or DMX universe). In this way, and generalizing to more than one
receiver, the DMX information sent by one LM-3E will be received for all the LM-3R configured in the same
group as the LM-3E transmitter.
Note: just one LM-3E can be associated to one or more LM-3R.
WORKNET is an own protocol that works in any standard TCP/IP network. The protocol is UNICAST, in
order to don't decrease network efficiency.
As seen before in this document and in LM-3E user manual, both LM-3E and LM-3R are automatically
configured, and they don´t need any network configuration. They automaticallly obtain an IP address and a
SubNet Mask, so that they belong to the same subnet in order to can communicate each other.
1.2 ART-NET MODE
In Art-Net mode LM-3R operates as an Art-Net node, receiving all the information sent by an ArtNet
compatible transmitter device. In this case the group concept is replaced by universe, uncluding Subnet
concept, just as Art-Net protocol specifies.
As seen before, LM-3R is automatically configured, and it obtains an IP address and Subnet Mask just as
Art-Net protocol specifies.
1.3 WEB SERVER
LM-3R is a plug and play device. By default, it is automatically configured like an ArtNet device, with an IP
address 2.x.x.x and SubnetMask 255.0.0. Each LM-3R has a sticker at the bottom with its default settings.
Although LM-3R is plug and play, it offers a user-friendly web-based management interface for the
configuration of the network features. To connect to the web interface, you must set your PC IP address to be
on the same subnet as the LM-3R (that is, the PC and LM-3R addresses must both start 2.x.x.x, with subnet
mask 255.0.0.0). Then, to access the configuration menu use your web browser to connect to the
management interface using the default IP addres, shown in the sticker at the bottom of the device.
