6.3 Operation with a DMX controller
GB
DMX is short for Digital Multiplex and means dig-
ital control of several DMX units via a common
control line. For operation via a DMX controller
(e. g. DMX-1440 or DMX-510USB from "img
Stage Line") the spotlight is equipped with 11
DMX control channels. However, it can also be
controlled via 6, 5, 4 or 3 channels only, depend-
ing on the requirement. The functions of the
channels and the DMX values are indicated in
chapter 6.3.5.
6.3.1 DMX connection
For the DMX connection, the unit is provided
with 3-pole XLR jacks of the following pin config-
uration:
pin 1 = ground, 2 = DMX-, 3 = DMX+
For connection, special cables for high data flow
should be used. Standard microphone cables
with screening and a minimum cross section of
2 × 0,22 mm
2
and with a capacity as low as pos-
sible can only be recommended for a total cable
length of up to 100 m. For cable lengths exceed-
ing 150 m it is recommended to insert a DMX
level matching amplifier (e. g. SR-103DMX from
"img Stage Line").
1) Connect the plug (6) of the cable DMX IN to
the inline jack of the supplied cable with the
XLR plug (5) and screw together the plug
connection with the cap nut. Connect the
XLR plug via an extension cable to the DMX
output of the controller or, if further DMX-con-
trolled units are used, to the DMX output of
the last DMX-controlled unit of the DMX sig-
nal cable.
2) If further spotlights ODP-483RGBW are used,
connect the first spotlight via the inline jack of
the cable DMX OUT (3) to the plug (6) of the
cable DMX IN of the second spotlight. Con-
nect the second spotlight to the third spotlight
in the same way etc. until all units have been
connected in a chain.
If the DMX connection cables between the
spotlights should be too short, use suitable
extension cables (e. g. ODP-34DMX from
"img Stage Line", length 2 m).
3) If the DMX control should not function cor-
rectly during the operation, terminate the
DMX output of the last unit of the chain with a
120 Ω resistor (> 0.3 W). To terminate the
DMX output of an ODP-483RGBW, the easi-
est way is to separate an extension cable
ODP-34DMX and to connect the resistor to
the pins 2 and 3 of the plug. Connect the plug
with the resistor to the inline jack of the cable
DMX OUT.

6.3.2 Adjusting the number of DMX channels
To be able to operate the ODP-483RGBW with a
light controller, the DMX start address (
ter 6.3.3) and the number of DMX channels have
to be adjusted. The number of DMX channels
depends on the required functions and possibly
on the number of the control channels available
at the controller. Chapter 6.3.5 provides the
information about the functions which are pos -
sible for 3-channel, 4-channel, 5-channel,
6-channel and 11-channel operation. Select the
number of DMX channels accordingly:
1) Press the button MENU so many times until
the highest menu level is reached (in fig. 2 on
the very left).
2) Press the button UP or DOWN so many times
until the display shows
3) Press the button ENTER. The display shows
the present adjustment:
11 channels
(
chapter 6.3.5, figs. 11 + 12)
3 channels
1 = red, 2 = green, 3 = blue
4 channels
1 = dimmer, 2 = red,
3 = green, 4 = blue
4 channels
1 = red, 2 = green,
3 = blue, 4 = white
5 channels
1 = dimmer, 2 = red, 3 = green,
4 = blue, 5 = white
6 channels
1 = dimmer, 2 = red, 3 = green,
4 = blue, 5 = white, 6 = stroboscope
3 channels
1 = colour, 2 = colour saturation,
3 = brightness
4) Select the adjustment with the button UP or
DOWN.
6.3.3 Adjusting the DMX start address
To be able to operate the spotlight with a light
controller, adjust the DMX start address for the
first DMX channel. If e. g. address 17 on the DMX
controller is provided to control the function of
the first DMX channel, adjust the start address
17 on the ODP-483RGBW. The other DMX
channels of the ODP-483RGBW are then auto-
matically assigned to the following addresses.
An example with the start address 17 is shown
below:

the very left).
2) Press the button UP or DOWN so many times

4) Adjust the start address with the button UP or
DOWN.
Note: A point flashes on the display when the spotlight
receives DMX signals.
6.3.4 Using subaddresses
By using subaddresses, up to 66 spotlights
chap-
(spotlight groups) can be controlled independ-
ently of each other via a single DMX start
address. Thus, the number of DMX-controlled
units which is possible as a maximum is consid-
erably increased. The selection of spotlights with
a subaddress is made via the DMX channel 11
(fig. 12). All spotlights with a subaddress may be
controlled in sync if the DMX channel 11 is
adjusted to a DMX value less than 10.
1) Adjust the spotlight for the control of 11 DMX
channels,
