DXT M17 - DMX RDM Merger
OVERVIEW
The M17 DMX/RDM Merger allows merging and switching
between two DMX sources in a one universe system. Through
the use of automatic DMX512 sensing, across four operating
modes, any port may detect a roving DMX512 source and act
as an input while the other two Port output the signal;
or two inputs may be merged together; or the user may
select between inputs; or a priority scheme may be invoked. The module is RDM discoverable and configurable,
as well as daisy-chainable.
CONNECTIONS
The M17 DMX/RDM Merger features terminal strips that can be removed
from the card to facilitate easy wiring installation or
replacement. Make the following connections, WITH THE POWER
TURNED OFF.
POWER
The M17 will operate on a range of voltages from 9-30 volts DC. Each
eDIN module requires 250mA. Observe the correct polarity when
connecting to V+ and V-. A second set of terminals are provided as a
thru connection to other eDIN modules. The EARTH GND terminal must
be connected to the enclosure’s chassis or electrical ground terminal to
ensure EMC compliance.
DMX512
DMX512 (DMX) connections consist of a shield and data pair.
Connect DATA+ and DATA- to D1+ and D1-. Observe the same polarity
convention throughout the system. Connect the cable shield or common
wire to the SHLD COM terminal.
DMX TERMINATE
Each port on the M17 is auto-terminated as required by its operation.
STATUS INDICATORS
POWER
Red. Steady glow indicates each port’s isolated power
supply is OK; off indicates no power. If all LEDs are
off, check that the module is receiving power.
INPUT
Amber. Steady glow indicates port latched to active
DMX source. Input and Output off on all ports
indicates no DMX source.
OUTPUT
Green. Steady glow indicates port is transmitting
DMX. Input and Output off on all ports indicates no
DMX source.
FUNCTION
Red. Steady glow indicates the current operating
mode. Flashing indicates the module is in edit mode.
STATUS INDICATORS
To configure, press and hold the function button until the current function
LED begins to fiash. Momentarily release then press the button to cycle
through the operating mode options. Once the desired mode is selected,
release the button. After three seconds, the LED will change to a steady
glow and the new mode will take effect.
Installation Instructions
DXT M17 - DMX RDM Merger
OPERATING MODE: RDM HUB
Detects and latches to a DMX input applied to any port. Ideal when
a single console or controller is moved between multiple locations in a
venue.
All DMX lines are wired back to the M17 DMX/RDM Merger card.
When no DMX is present, the Merger will scan all ports looking for an
input signal. Once a DMX input is detected, that port becomes the input
and the other two ports become DMX outputs. If a second DMX source is
applied to another port, that source will be ignored until the initial source
is disconnected.
While in RDM Hub mode, the Merger card acts as an RDM
responder and splitter. Any connected downstream RDM devices may
be discovered and configured using an RDM-enabled console or other
RDM controller.
OPERATING MODE: RDM A/B
Allows the user to select input on Port B over Port A, using a
maintained dry contact closure between COM (pin 3) and A/B (pin 1) of
the three-position contact closure terminal block. Ideal for selecting a
backup console over the primary console or source, on the fly.
Ports A and B are wired to DMX sources while Port C goes to the
lighting system. With no connection between COM and A/B, input signal
on Port A will be output, and any input on Port B will be ignored. When a
dry contact is closed and maintained between COM and A/B, input
signal on Port B will be output and any input on Port A will be ignored.
The switch between sources is immediate.
NOTE: If there is no DMX signal on the selected input port, no DMX
will be output by the card.
While in RDM A/B mode, the M17 acts as an RDM responder and
splitter.
Any connected downstream RDM devices may be discovered and
configured using an RDM-enabled console or other RDM controller.
OPERATING MODE: PRIORITY
Provides predictable signal priority arrangements of DMX sources.
Ensures a primary console will take over completely from stage
management panels, architectural controllers and other data sources.
Wire the theatrical console to Port A and the architectural controller to
Port B.
When signal ceases on Port A, after a one second delay, the card will
switch to Port B. Should signal return on Port A, the card will
immediately output that signal.

Part No. 912-00014-013 Rev A
NOTE: The DMX source must cease entirely for priority to take effect.
Bringing all DMX levels to zero is not the same as the signal stopping or
disconnecting.
NOTE: Do not install any DMX receiving devices between the DMX
source and the M17 card when in Priority mode. Intermediate devices will
not function correctly should a different DMX source have priority.
While in Priority mode, the M17 acts as an RDM responder.
However, all RDM communication with downstream devices are disabled.
Any connected downstream RDM devices will not be discovered and
cannot be configured.
OPERATING MODE: MERGE
Allows slot-by-slot, HTP (highest-takes-precedence) merging of two
DMX sources. For example, allows use of a remote controller while the
main console is also active.
Hook one source to Port A and one to Port B and the lighting system is
wired to Port C.
While in Merge mode, the M17 acts as an RDM responder.
However, all RDM communication with downstream devices are disabled.
Any connected downstream RDM devices will not be discovered and
cannot be configured.
RDM PROPERTIES
The M17 DMX/RDM Merger is fully compliant with the E1.20
Remote Device Management standard. Operating modes may also be set
remotely using an RDM-enabled console or other RDM controller.
The M17 has two custom properties, which may only be set using an
RDM-enabled console or other RDM controller.
Hold Last Look: On loss of all DMX inputs, output may be held for zero
seconds, thirty seconds, 1 minute, 5 minutes or forever. Default is zero
seconds.
DMX512 Output Speed: The DMX output frame rate may be set
to: Slow, Medium or Fast. Default is Fast.
