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 10
DMX control channels. However, it can also be
controlled via 5, 4 or 3 channels only, depending
on the requirement. The functions of the chan-
nels and the DMX values are indicated in chap-
ter 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 (1) of the cable DMX IN to
the inline jack of the supplied cable with the
XLR plug (6) 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-361RGB are used,
connect the first spotlight via the inline jack of
the cable DMX OUT (4) to the plug (1) 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-361RGB, the easiest
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-361RGB 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 and
10-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:

10 channels
(
3 channels
1 = red, 2 = green, 3 = blue
4 channels
1 = dimmer, 2 = red,
3 = green, 4 = blue
5 channels
1 = dimmer, 2 = red, 3 = green,
4 = blue, 5 = 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-361RGB. The other DMX chan-
nels of the ODP-361RGB are then automatically
assigned to the following addresses. An exam-
ple with the start address 17 is shown below:

2) Press the button UP or DOWN so many times
until the display shows
3) Press the button ENTER. The display now
shows
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
(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 10
(fig. 10). All spotlights with a subaddress may be
controlled in sync if the DMX channel 10 is
adjusted to a DMX value less than 10.

value which corresponds to the subaddress
of the spotlight ( chapter 6.3.5, fig. 10).
