ModDMX
ModDMX: DMX gateway
ModDMX module allows to handle, through the
Contatto
bus, up to 32 DMX devices. ModDMX module makes pos-
sible the communication on the first 64 of 512 DMX chan-
nels allowed by this protocol.
ModDMX module can be successfully employed in profes-
sional and domestic lighting applications, where systems
communicating by the USITT DMX-512 protocol are used,
as theaters, disco clubs, architectural lighting, etc.
ModDMX module features the following characteristics:
✗
all functions are managed by the module and can be
controlled by any real or virtual input of the system, by
supervisor or by video-terminal
✗
possibility to control the DMX system from one or more
pushbuttons connected to the
Contatto
bus
✗
up to 64 sceneries are available to realize “real time”
scenes; the sceneries are stored in the non volatile
memory of the module
✗
management of fade times
✗
management of different rooms by the same ModDMX
The module can manage up to 64 DMX channels, but the
total amount of connected DMX devices may be lower than
64 if the device gets more than one channel. Moreover, the
total amount of connected DMX devices may be anyway
lower than 32. ModDMX module can operate exclusively in
system using MCP XT controller. Up, Down and Single
Command function, with or without one-touch feature, can
be performed by the module from any real or virtual input of
the system (see in the following of this manual); in addition,
it is possible to save and recall the sceneries.
The module features a removable 5-way terminal block for
the connection to the Contatto bus and a fixed 3-way ter-
minal block for the DMX line. A green LED near to the bus
terminal block shows that the module is supplied, while a
yellow LED near to the 3-way terminal block shows the
presence of communication on the DMX line. ModDMX is
housed in a standard DIN 3M box for rail mounting.
Note: this manual applies to ModDMX modules equipped by
firmware version 2.2 or higher.
Address programming
ModDMX module takes 1 output address, 1-channel 16-bit.
The address must be assigned by FXPRO programmer. A
white label on the front panel allows the writing of the as-
signed address for an immediate visual identification.
Wiring diagram
The following schematic diagram shows the connection to
be made between ModDMX module, the
Contatto
bus and
the DMX line, using proper cables as described in the re-
lated table.
Generally, the DMX devices feature a female XLR 5-way or
3-way connector, therefore in this case the cable of
ModDMX must be properly wired to a male XLR connector
(not provided) according to the specification of the manu-
facturer of the device.
Even if the standard specifies a maximum of 32 devices for
the DMX line, as a good rule do not override a total amount
of 16-20 devices. If the number of devices is higher than
20, use proper line splitters to connect the devices overrid-
ing this limit.
