DMX Basics and Pin-Outs
The Net3 Two-Port gateway sends and receives DMX512 control signals. The unit can contain a pair of 5-pin DMX
input connectors or a pair of 5-pin DMX output connectors. DMX cables must be acceptable for DMX data
transmission (not microphone cable) and should follow the standard pinout. The optional secondary data pair is not
used by the Net3 Two-Port gateway.

DMX Termination
A pair of compact switches (S1 and S2) located on the rear panel of the Two-Port is
provided to enable and disable DMX termination. These switches are factory
defaulted to "On" for every gateway. The most common reason to disable this
termination is to support "touch and go" connections. "Touch and go" implies that
you land DMX wiring on the connector for the gateway and continue to another DMX
device (daisy-chain). This practice is uncommon when using DMX gateways.

RDM Basics
Net3 gateway software now supports Remote Device Management (RDM) protocol. By default, RDM discovery is
not enabled on Net3 gateways. To enable RDM on the Net3 Two-Port gateway, use ETC's Net3 Gateway
Configuration Editor (GCE) software. Please see the GCE online help files for more information on activating RDM
on your Net3 gateways.
About RDM
Remote Device Management (RDM) is a protocol enhancement to DMX512 that allows bidirectional communication
between a lighting system controller and attached RDM-compliant responder devices over a standard DMX line.
This protocol allows configuration, status monitoring, and management of these devices.
An RDM Controller is the device that initiates communication with one or more RDM Responder devices. Examples
of responders are RDM-enabled edge devices such as color scrollers, dimmers, moving lights, and LED fixtures.
Net3 DMX/RDM gateways support 32 RDM devices per-port, just like DMX devices.
Compliant DMX512 and DMX512-A devices (non-RDM devices) are fully functional when RDM is present.
RDM was developed by the ESTA Technical Standards and can also be referenced as ANSI E1.20.

Menu Structure
The Net3 Two-Port gateway has only a one button interface. Pressing the [Menu] button repeatedly cycles through
the menu, displaying mostly informational data. On certain menu items you are prompted to press and hold the
[Menu] button for a period of 5 seconds to change a state or switch between operating modes. The Net3 menu
structure is displayed below for your convenience.
Net3 v5.1.x Menu
•
DMX universe numbers up to 999 are displayed on the front panel. Universes that are higher than 999, or flexibly patched
outputs, are indicated by "..." (you must go to the port screen to see full details).
My DMX Gateway

The unit displays either the "gateway name" or the "IP Address" as well as each port and its port status.
999

•
Port Status includes:
-- arrow directed toward the number indicates an input (999
-- arrow directed away from the number indicates an output (999
-- an X indicates the universe port is disabled, no universe number is shown (X)
-- a dimmer doubled port displays only "DD" (you must go to the port screen to see full details)
-- when a port is set to download mode, "DNLD" displays.
-- AIP inputs are indicated as "AIP"
-- a port will blink on the display when it does not have DMX connected (input) or has no valid source data (outputs).
•
displays the port priority mode either "Output", "Input Pri ***" (where *** indicates the port is set with per-address priority),
or "Input Pri 100" (where 100 is the priority value for that port). Always displays either "Input" or "Output".
Port 1 Output
