DMX Termination
Termination is required for all DMX systems and belongs at the source
(beginning) of a DMX line and at the last device physically connected in
the line. A termination switch is located internally for each input/output
and can be configured for DMX termination (IN), No termination (OFF) or
RDM termination (OUT). By default, the DMX termination switch is set to
the appropriate position based on the port type (Female XLR and RJ45 set
to OUT and Male XLR set to IN).
If you need to change the termination setting, perform the following steps:
Termination
switch location
1.
Disconnect your gateway from all power supplies.
2.
Remove the gateway from the back box or portable
enclosure. The termination switches are between the
two printed circuit boards, one on either side of the
gateway.
3.
Set the termination switch to the appropriate
configuration.
About RDM
Remote Device Management (RDM, ANSI E1.20) is a protocol enhancement to DMX-512 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. Compliant DMX-512 and DMX-512-A devices (non-RDM devices)
are fully functional when RDM is present. The Response Mk2 Gateway supports up to 256 total
RDM devices across its ports using standard DMX system design practices.
Note:
RDM is currently only supported on DMX Output ports.
RDM Basics
By default, RDM discovery is not enabled on the gateway. To enable RDM on the gateway, use the
ETC Concert software or the user interface on the front of the gateway. Please see the Concert
online help files for more information on activating RDM on your gateways or see
.
