Overview

The NODE4 is an Ethernet to DMX bridging device. It accepts Artistic License's ArtNet
(version 3 or prior), PLASA’s Streaming ACN (ANSI E1.31), or Draft Streaming ACN
protocols. There are four fully isolated DMX512 ports. Each port can be configured as
either an input or as an output. Each of the connectors can be mounted on either the front
or rear panel. Their location can be changed in the field to accommodate fixed or touring
installations.

The factory default configuration covers most applications. An easy to use control panel
gives access to all network settings if a change is needed. The backlit 2 line by 20
character LCD and LED indicators give quick status feedback.

To configure the NODE4 ports, choose what you want to set up by pressing the port or
network adapter SELECT key. Use the arrow keys to find the option you want to change
and press ENTER. Use the arrows to change the value and press ENTER again to save.
You can use the BACK key at any time to disregard changes and return to the previous
menu.

The NODE4 features a universal input power supply and a rugged enclosure. An optional
rack mounting kit is available (model RK16-1). Holes are provided for truss mounting using
a C-clamp or half-coupler.

1 2 4 6 7 8 9

1) 20x2 Character LCD screen: Used to show data to the user based on the current

selection. After power up, the display shows the unit's current name and IP address.

2) Direction Pad: Consists of UP, DOWN, LEFT, and RIGHT keys. Use these keys to edit
configuration items and navigate the menu system.

3) BACK key: The BACK key is used to return to the HOME screen from one of the
information screens or to exit an editing screen without saving the changes.

4) ENTER key: Used to edit the item you are currently viewing. When editing of a
parameter is complete, press ENTER again to save the changes.

5) NET key: The NET key is used to enter the network settings menu. From there the
DHCP mode, IP address, Subnet Mask, and network protocols can be changed, The MAC
address can also be viewed.

6,7,8,9) Keys A, B, C, and D: These keys are used to select the corresponding DMX512
port. In each port's menu, the universe and the port's input/output status can be edited. In
addition, the levels of each DMX512 channel on the selected port can be viewed.

10) Front panel LEDs (not referenced on the diagram): The LEDs show the status of each
of the NODE4 ports. When a port’s SELECT button is pressed, the blue LED above that
button illuminates to indicate that it is selected for viewing or editing. The green NET
TRANSMIT LED flickers while the NODE4 is sending data out on the Ethernet port. The
red NET RECEIVE LED flickers while the NODE4 is receiving data from the Ethernet port.
Each of the DMX512 ports has a green TRANSMIT LED and a red RECEIVE LED. The
TRANSMIT LED flickers while DMX512 data is being sent from the associated DMX512
port (output mode). The RECEIVE LED flickers while DMX512 data is being received on
the associated port (input mode).

The rate at which each of the TRANSMIT and RECEIVE LEDs flickers provides additional
diagnostic information. Each LED will change its state (on or off) when a new packet of
data is transmitted or received. For example, if one of the DMX512 ports is configured as
an input, the flickering RECEIVE LED will show the relative update rate of the incoming
signal.

The Menu System

HOME Menu

The HOME page shows the unit's name and current IP
address. This is the default screen at startup, and you can
return to it at any time by pressing the BACK key until you

NET Select Menu

To Enable/Disable DHCP press the NET select key which
will take you to the network select menu. The first page
displayed is the DHCP Enable/Disable page. Press
ENTER to enable editing. Use the UP or DOWN keys to
select from Enable or Disable. When a final selection has

been made, press ENTER to save the changes. Press BACK to exit without saving.

To set the IP Address press the NET select key. This will
display the network select menu. Press DOWN once. The

e IP Address page will be displayed. Press ENTER to begin

editing the IP address. The IP address can not be edited if

DHCP is enabled. If DHCP is disabled, the LEFT and
RIGHT arrow keys can be used to select the digit to edit. Use the UP and DOWN arrow
keys to change the selected digit. After editing all digits, press ENTER to save changes.
Press BACK to exit without saving.

arrow key twice to display the Subnet Mask page. Press

ENTER to edit the Subnet Mask. The Subnet Mask can

not be edited if DHCP is enabled. The UP and RIGHT
keys increase the number of ones in the Subnet Mask. The LEFT and DOWN keys
decrease the number of ones in the Subnet Mask. Configuring the Subnet Mask in this
fashion is consistent with the CIDR notation (More information can be found by searching
for CIDR online), and allows all valid Subnet Masks in the range from X.X.X.X/8 to X.X.X.X/
24 or 255.0.0.0 to 255.255.255.0.
