Program
The logical sequence of commands or assignments which are
achieved by the internal control system of the LED flood light.
Every function, that means everything what the flood light is able to do,
is based on a program or a part of a program. Which program or which
part of a program is active, depends on exactly defined terms and
conditions. Such terms and conditions might be e.g. operating modes
(see chapter 6.3.2.1 Technical information and specified definitions).
Special program
An autonomous running light-example. Special programs are stored in
the internal memory disk of the LED flood light. Some of the special
programs can be activated by special DIP- switch settings in stand-
alone mode. During DMX- and RDM-DMX-mode all special programs
can be performed.
Type of control
Describes the possibilities of controlling the LED-flood lights
1. Mode without external control
2. Mode with external control
Stand-Alone mode
Type of control mode, which doesn´t need an external control.
With this type of control you can activate different special programs
by using the DIP-switch.
DMX- and RDM-DMX-mode
These are types of control, where the LED-flood lights are controlled
by a Bus-system. When using these mode types you need an external
control system, e.g. a mixing desk. The transfer of information
between external control system and LED-flood light is done by
DMX- or RDM-DMX-protocols.

DMX – protocol (DMX = Digital Multiplex)
Is a standardized digital controlling protocol used in stage- and event
technology which controls dimmer, “intelligent” flood lights and effect
DMX has been standardized by the USITT (“USITT DMX512”,
“USITT DMX512/1990”) followed by DIN 56930-2 in 2000 and
ANSI E1.11 (known as DMX512A) in November 2004.
The data stream of DMX protocols always flow in one direction: from
the external control system to the end unit in use.
RDM- protocol (RDM = Remote Device Management)
Is an extension of the DMX – protocol. It allows a bi-directional
communication between external control system and end unit, which
means the data stream flows in two directions.
With RDM the operating comfort increases considerably. E.g. re-
programming of addresses, diagnose of mistakes and transferring
other important information.
The protocol is defined in the “American National Standard
E1.20 – 2006, Entertainment Technology, RDM Remote Device
Management over DMX512 Networks”, published by the
Entertainment Services and TechnologyAssociation (ESTA).
The LED flood light Ittermann SpotLight of the serie iSL3014 has been
designed for in-room use but not for use in humid rooms, e.g. saunas
or bath-rooms.
LED flood lights with small angle of radiation are suitable for
punctual accentuation of objects. LED flood lights with a wide angle of
radiation optics are suitable for the illumination of rooms.
The flood lights can be fixed at walls and ceilings.

3.2 Design and over all functions
The LED flood light Ittermann SpotLight of the serie iSL3014 consists
of 14 high performance LEDs, which work with co-current flow. The
angle of radiation depends on the attached optics.
Illuminants and lenses of the LED flood light varies from
type to type, see chapter 3.4 Technical data
The active thermic management caters for a high effectiveness of light
and a long life of the LEDs.
By using the DIP-switches at the back of the light you can choose the
types of control.

5.2 Installation and electrical connection
- Choose the place of installation of the LED flood light where
adequate air exchange is assured in the neighborhood.
If that is not always possible the active thermic management of
the Ittermann SpotLight LED-flood light prevents a strong
temperature rise of the luminous element and therefore a
reduction of the duration of life.
- Please bring the DIP-switches into the following positions:
This switch setting starts the special program No. 17 in Stand-
Alone mode. All LED-groups will be activated one after
another.
- Mount the ceiling- or wall fixing brackets at an applicable place
and tighten the screws strong. The ceiling- or wall fixing bracket
shall only be assembled at a horizontal or vertical seat with
adequate consistency and tensile-loaded capacity.
The montage of the ceiling- or wall fixing bracket should be the
way that it is impossible for the LED flood light, to fall down
Please take care that the knurled nuts a tightened very strong
after hang on and adjust the LED flood light!

Special programs in Stand-Alone mode
(Description on the example of the iSL3014-RGBW)
Five special programs are available.
Type A Each colour can be switched separately and for each
colour there are four levels of lightness
(0 % = off, 25 %, 75 % and 100 %).
Type B All colours are active, the lightnes is defined by the DIP-
switch SW2; 64 levels of lightness are available.
With RGBW this setting will cause white light with 64
possible lightness levels.
Type C 8 special programs with white and
8 speed levels can be justified.
Type D 8 special programs with stroboscopic effects and
8 speed levels can be justified.
Type E 8 special programs without white and
8 speed levels can be justified.

The DMX controlling protocol is based on a RS-485-interface. The
data transfer occurs symmetric and serial. Because of the symmetric
data transfer DMX has a high interference resistance, because
external errors affect both data links constantly. The receiver analyzes
not
For the construction of connections 5-pole XLR-jacks are specified.
Because it is cheaper 3-pole jacks are used often, too. But that
doesn´t fit the norm.
For the connection lines please use high quality cables, which are able
to transfer the data with high speed (no microphone cables). Capable
are Twisted-Pair-cables with an impedance level of app. 120 ohm.
For connecting the Itermann SpotLight LED-flood lights Cat5-Patch
cable are provided.
see Chapter 4 Supplies
To connect supply voltage and busses of the Ittermann SpotLight
LED-flood light, RJ-45 plug connectors are used. These plug
connectors are usual for ISDN (IAE), structured wiring and computer
networks.
The decision to use for the iSL-LED flood lights RJ-45 plug connectors
has been taken for design reasons. The small and handy design of the
flood light would have not been possible when using XLR-plugs and
moreover an additional plug connector has to be placed for the supply
voltage in that case.
The special RJ-45 configuration of the plug connector on the
Ittermann SpotLight LED-flood light with it´s supplies allows sharing a
maximum of 216 watt in one row (with a supply voltage of 48 V),
without to excess the capacity of the loading system.

DMX-Networks
DMX-Networks are systems with one transmitter and several receivers
which are connected by bus lines. Transmitter can be e.g. PCs or light
mixing boards and receivers can be e.g. Dimmer, intelligent flood lights
and effect equipment.
The bus stations (transmitter and receiver) are switched back to back
(bus-topology).
One transmitter can be connected to a maximum of 32 receivers. For
more than 32 receivers you have to install a repeater. In case of
branching you should apply splitter (Repeater and splitter amplify and
regenerate the bus signal).
Most bus-technologies start with a transmitter at the beginning of a
chain. To prevent signal-reflections within this constellation – even in
very long chains – it is necessary to install a 120 Ohm-terminator at
the bus-end, after the last receiver. If the transmitter is not located at
the end of a chain, both ends have to be terminated.
The control system roots control information to the receiver by
DMX-protocol. This information is completed by the receivers. You can
power 512 channels with information by using the DMX-protocol.
Channel means, within this context, the controllable function of a
receiver.
The transmitter gets to know how to complete a function by 8 data bits,
which built a DMX-slot together with one start bit and two stop bits.
With 8 data bits a space of 256 DMX-accounts (0 to 255) are possible.
Which function is saved on which channel and is controlled with which
DMX-account is defined by the producer in a DMX-channel-
configuration-chart.
The data transmission works as follows:
One after another a maximum of 512 slots are send by bus lines from
the transmitter to the receivers. Which channel shall use the data of
one slot is regulated by addresses. Each channel gets an address
continuously from 1 to 512. After a start mark each receiver has to
count the transferred slots and filter the special slot which he is able to
react on because of it´s address.
As most receivers in a bus are multifunctional devices, which means
more than one channel has to be controlled, such a device gets a

DMX-start address. This receiver evaluates from the start address the
used number of consecutive slots. The start address of the next
receiver is forwarded of this number of addresses, which the receiver
before has evaluated.
For example: Does the first receiver evaluate in the bus the
addresses 1 – 8, the start address of the next
receiver is 9.
In Chapter 6.3.1.3 “Adjustment of addresses at the DIP-
Switches” of the iSL3014, you find the description for the
addressing of the Ittermann SpotLight LED-flood light.
A DMX-Slot consists of:
- one start bit
- one start byte (at the beginning of the DMX package)
respectively 8 data bits (control-information for the single
channels)
- two stop bits.
A DMX-package consists of:
- one “break” (or “reset”) with the logical index 0:
the minimum length has to be 88 µs
- one “mark after break” with the logical index 1:
the minimum length has to be 8 µs
- a first slot, consisting of:
one start bit, one start byte and 2 stop bits
- a “mark” between the slots with the logical index 1
- a second slot, consisting of:
one start bit, 8 data bits (controlling information for the first
channel) and 2 stop bits
- one “mark” between the slots, logical index 1
- The 512nd slot, consisting of one start bit, 8 data bits (controlling
information for the 512nd channel) and 2 stop bit
- one “mark” between the packages, logical index 1.

All 512 control-information might be, but need not to be transferred. If
the transfer is interrupted any time it can be activated again by
sending a new DMX package. The “break”-sequency is always the
start of a new package.
The start byte has account 0 at DMX. All receivers, which only
understand DMX and no other protocol language (e.g. RDM), must
ignore packages which have a start byte unlike 0.
The speed of data transfer is 250 kbits/s. Therefore the speed of data
transfer for one bit is about 4 µs, for a slot 44 µs (11 x 4 µs) and for a
data package (512 slots) about 22.528 µs (512 x 44 µs).
The length of a DMX package results from the sum of parameter:
+ 88 µs (break)
+ 8 µs (mark after break)
+ 44 µs (first slot with start byte)
+ 22.528 µs (512 slots; data for channels 1 – 512)
= 22.668 µs.
This corresponds to a frequency of 44,11 Hz. The maximum break
between two DMX packages is fixed with 1s.
