Product Overview and Document Scope

The Doug Fleenor Design E1REL20A and E1REL20A-2POLE Relay Packs control loads
attached to dry contact air-gap relays. Control for these products comes from ArtNet and
sACN (E1.31) Ethernet protocols. The protocols are configured using an internal web
server. Connection and configuration of the webserver are described in this document.

Specifications concerning power input, types of load and connector for each model
number are available in a separate data sheet.

Configuration Overview

Setup begins with a physical connection to a network using the Ethercon connector.
Once physically connected, appropriate IP addresses must be set in order to access the
web pages and configuration options. The two methods for establishing this web
connection are using Dynamic Host Configuration Protocol [DHCP] and Node
Discovery, or Static IP addresses. Once connected and configured, the relay stores the
settings, which persist after removing power.

Installers may choose to bench configure these products (typically with Static IP) prior to
installation, or place them into networks specified in a way where connection is possible
after being physically connected into the system (typically with DHCP and Node
Discovery on Windows 7 or higher). Mac and Linux users who require additional support
can give us a call at [phone].

Default IP Configuration

Unique IP addresses are assigned to each DFD Ethernet product at shipping time. The
IP Address and Subnet Mask are labeled on the bottom of each unit. DHCP is also
enabled at shipping time. When a default configured relay is connected to a network
that does not have a DHCP server, the IP from the bottom of the unit is used.

For pages other than the status page the default Username and Password are:

Username: admin
Password: dmx512

Connect using DHCP and Node Discovery

This procedure is valid for PC’s using Windows 7 or newer. Mac and Linux users who

require assistance can give us a call at [phone].

To begin setup, plug in your Ethernet Relay and ensure that the red “PWR” LED

illuminates. Run a cable from the Ethercon connector to a router configured to serve
DHCP (default for most ‘home’ routers). Run another cable from the router to a
Windows 7 (or newer) PC with an Ethernet card set to use DHCP (standard for most
‘home’ PCs). Next, download Node Discovery from our webpage at www.dfd.com. To
do so, navigate to the Node Discovery Page under the Ethernet Products heading.
Node Discovery is a simple application that allows you to find your Doug Fleenor Design
Ethernet devices on your network. There is no need to install the program, just unzip the
file and double-click on NodeDiscovery.exe. Below is a screenshot that displays the
output of a successful Node Discovery. Type in your IP and subnet, click Discover, and
then double-click on the Node you wish to configure. It opens the device’s built-in
webserver for configuration.

You will be brought to a page in the Ethernet relay’s built-in webserver to configure your
Ethernet relay. The username and password are as follows:

Username: admin
Password: dmx512

Once entered, you can edit your password in the Admin tab.

Connect using STATIC IP

To begin setup, plug in your Ethernet Relay and ensure that the red “PWR” LED
illuminates. Run a cable from the Ethercon connector on the back of the Ethernet Relay
to the Ethernet port of your computer. The computer’s Ethernet interface will need an IP

Address set to 10.X.X.X and a Subnet Mask of 255.0.0.0. The X’s can be any number

between 1 and 255, but cannot be the same as the IP printed on the bottom of the relay.
Open any web browser and type the IP Address from the bottom of the unit into the
