4 Operation
The operating modes and the setting functions
are selected via a menu by means of the buttons
MENU, ENTER, UP and DOWN . Figure 3 on page 2
shows the selection of the modes and functions
via the menu and the indications on the display .
4.1 Independent operation
For independent operation, it is possible to set
the brightness for cool white and warm white,
to activate the stroboscope function and to set
the flash rate on the spotlight .
1) Press the button MENU repeatedly until the
display shows
.
2) Press the button ENTER . , or
and a
number will appear on the display .
= brightness cool white (0 – 255)
= brightness warm white (0 – 255)
= flash rate (0 – 20 Hz) of the stroboscope
3) Use the button ENTER to select the three set-
ting functions one after the other and then use
the button UP or DOWN to set the brightness
or flash rate . The colour temperature of the
light beam is defined by the brightness ratio
between cool white and warm white .
Note:
Do not use the button MENU to exit the menu
item for the brightness or the flash rate before switching
off the spotlight . If you do, the spotlight will remain dark
when it is switched on again .
4.2 Synchronous control of multiple
spotlights (master / slave mode)
Multiple spotlights ODC-100 / CTW and PARC-
100 / CTW (also a combination of both) may be
combined . The brightness and flash rate settings
made at the master unit will be automatically
transferred to the slave units .
1) Connect the spotlights with each other in a
chain, using the DMX connections; please
refer to chapter 4 .3 .1, “Connection”, skipping
step 1 .
2) Set the master unit to the master mode and
all slave units to the slave mode:
a) Press the button MENU repeatedly until
appears on the display .
b) Press the button ENTER and then use the
button UP or DOWN to select:
= master mode for the master unit
= slave mode for the slave units
3) At the master unit, set the brightness and flash
rate desired .
4.3 Operation with a DMX controller
For operation via a DMX light controller (e . g .
DMX-1440 or DMX-510USB), the spotlight is
equipped with four DMX control channels . DMX
stands for

igital

x
and means digital
control of multiple DMX units via a common con-
trol cable . The functions of the channels and the
DMX values can be found in chapter 4 .3 .3 (fig . 6) .
4.3.1 Connection
For DMX signal transmission, special cables
should be used (e . g . CDMXN-…) . For cable
lengths exceeding 150 m or for control of more
than 32 units via a single DMX output, it is gener-
ally 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 to the DMX output of
another DMX-controlled unit .
For the spotlight ODC-100 / CTW, connect
the plug (C) of the cable DMX IN to the inline
jack (D) of the supplied cable equipped with
an XLR plug . Then fasten the nut to secure
this connection .

DMX connection ODC-100 /CTW
Use an extension cable to connect the XLR plug
to the DMX output of the light controller or, if
additional DMX-controlled units are used, to
the DMX output of the last DMX-controlled
unit .
2) Connect the output DMX OUT to the DMX
input of the second DMX unit . Connect the
output of the second DMX unit to the input of
the third DMX unit etc . until all DMX-controlled
units have been connected in a chain .
If the DMX connection cables between the
units are too short when interconnecting mul-
tiple ODC-100 / CTW spotlights, use suitable
extension cables, e . g .
ODP-34DMX length: 2 m or
ODP-34DMX / 10 length: 10 m
3) To prevent interference in signal transmission,
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): Connect a corresponding
terminating plug (e . g . DLT-123) to the DMX
output jack .
