Operation With A Dmx Controller; Connection; Setting The Start Address And The Number Of Dmx Channels (Dmx Set) - IMG STAGE LINE MATRIX-915LED Bedlenungsanleitung

4.4 Operation with a DMX controller

For operation via a DMX light controller (e . g .
DMX-1440 or DMX-510USB from IMG STAGE
LINE), the MATRIX-915LED is equipped with
50 DMX control channels . The unit can also be
controlled via fewer channels if the functions
provided are sufficient (refer to chapter 4 .4 .3)
or if the number of channels available on the
lighting controller is less than 50 .

4.4.1 Connection

For DMX signal transmission, special cables are
recommended (e . g . cables of the CDMXN se-
ries from IMG STAGE LINE) . For cable lengths
exceeding 150 m or when controlling more than
32 units via a single DMX output, it is generally
recommended to insert a DMX level matching
amplifier (e . g . SR-103DMX) .
1) Connect the input DMX IN to the DMX
output of the light controller or of another
DMX-controlled unit .
2) Connect the output DMX OUT to the DMX
input of the second DMX unit . Proceed in
the same way to connect the output of the
second unit to the input of the third unit
etc . until all DMX-controlled units have been
connected in a chain .
3) To prevent interference in signal transmis-
sion, in case of long cables or a multitude
of units connected in series, terminate the
DMX output of the last DMX unit in the
chain with a 120 Ω resistor (> 0 .3 W): Con-
nect a corresponding terminating plug (e . g .
DLT-123 from IMG STAGE LINE) to the DMX
output jack .
4.4.2 Setting the start address and the
number of DMX channels (DMX Set)
For separate control of all DMX units con-
nected to the light controller, each unit must
have its own start address . Example: If the
first DMX channel of the MATRIX-915LED
is to be controlled by the light controller via
DMX address 6, set the start address on the
MATRIX-915LED to 6 . All other DMX channels
of the MATRIX-915LED will be automatically
assigned to the subsequent addresses . Examples
with different start addresses:

Fig. 7 DMX address assignment
Via the main menu item "DMX Set", set the
start address and the number of control chan-
nels . For all other MATRIX-915LED to be con-
trolled in sync, set the same start address and
the same number of channels .
DMX control of the moving head will now be
possible . The DMX functions can be found
in chapter 4 .4 .3 . As soon as the unit receives
any DMX control signals, it will go to the DMX
mode: The display will indicate the start address
and the number of DMX channels (Fig . 3) .
If the moving head does not receive any
DMX control signal, it will go to the independent
mode . To switch off the LEDs instead, set the
menu item Black out to Yes via MENU  Run
Mode (chapter 4 .2) .
Hint: When two or multiple MATRIX-915LED are con-
trolled via the same start address, invert the moving
direction of one or multiple units (Pan / Tilt inverse, chap-
ter 4 .5) . Thus, with a pair of units, the heads will move
in opposite directions (mirror-inverted) .
