RDM Basics
Net3 Gateway software now supports Remote Device Management (RDM) protocol. By
default, RDM is not enabled on Net3 Gateways. To enable RDM on the Net3 Gateway,
Net3 Gateway Configuration Editor (GCE) is required. Please see the GCE 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
bi-directional 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 controllers are ETC's Net3 DMX/RDM 2-Port and 4-Port
Gateways and RDM-enabled consoles.
An RDM Responder is the device that replies to communication from a controller. Examples
of responders are RDM-enabled edge devices such as gel scrollers, dimmers, and moving
lights.
Net3 DMX/RDM Gateways support 32 RDM devices per port, just like DMX devices.
Compliant DMX512 and DMX512-A devices (non-RDM devices) are completely functional
when RDM is present.
RDM was developed by the ESTA Technical Standards and can be referenced as ANSI/
ESTA E1.20.
