6.1 DMX connection

For DMX connection, 3-pole XLR connectors with
the following pin configuration are provided:
Pin 1 = ground, 2 = DMX-, 3 = DMX+
For connection, special cables for high data flow
are recommended. Standard microphone cables
with screening and a minimum cross section of
2 × 0.22 mm 2 and with a capacity as low as possible
can only be recommended for a total cable length
of up to 100 m. For cable lengths exceeding 150 m,
it is generally recommended to insert a DMX level
matching amplifier (e. g. SR-103DMX from "img
Stage Line").
1) Connect the DMX input (9) to the DMX output of
the light controller.
2) Connect the DMX output (12) to the DMX input
of the following light effect unit; connect its out-
put again to the input of the following unit, etc.
until all light effect units have been connected in
a chain.
3) To prevent interference in signal transmission (in
case of long cables or a multitude of units con-
nected in series), terminate the DMX output of
the last DMX unit in the chain with a 120 Ω resis-
tor (> 0.3 W): Connect a corresponding termi-
nating plug (e. g. DLT-123 from "img Stage
Line") to the output jack.
6.2 Setting the DMX start address and
the number of DMX channels
For controlling the light effect unit with a light con-
troller, it is necessary to set the DMX start address
for the first DMX channel. If e. g. address 17 on the
controller is provided for controlling the pan of the
head, set the start address 17 on the TWIST-52LED.
The other functions of the TWIST-52LED are
automatically assigned to the 14 following channels
(in this example 18 – 31). In this example, the next
possible start address for the following DMX-con-
trolled unit would be address 32. (In the 16-channel
mode, 16 DMX channels are used, i. e. the next
possible start address for the following DMX-con-
trolled unit would be address 33.)
1) Set the DMX start address:
a) Press the button MENU (4) once so that the
display (5) shows DMX Address.
b) Press the button ENTER. The address
adjusted starts flashing on the display.
c) Press the button
To memorize, press the button ENTER.
2) Set the number of DMX channels to be used to
control the moving head:

a) Press the button MENU repeatedly until the
display shows Channel Mode.
b) Press the button ENTER. The number of
DMX channels starts flashing on the display.
c) Press the button
DMX channels (15Chan or 16Chan ). To
memorize, press the button ENTER.
3) To exit the setting mode, keep the button MENU
pressed until the LED DMX or MASTER (3)
lights up or wait for one minute and do not press
any button.
4) Once the control signals of the DMX controller
are received, the red LED DMX (3) lights up and
the display shows the number of DMX channels
and the start address. Now the TWIST-52LED
can be operated with the DMX controller.
To activate the light beam, set DMX channel
7 or 5* to a DMX value between 8 and 15 or to
255 and set the desired brightness via DMX
channel 6 or 4*, chapter 9.2.
*channel number for the 16-channel mode

7 Additional Functions

7.1 Offset correction

For fine adjustment of the head position, the gobo
wheels, the colour wheel, the prism and the focus,
settings for offset correction can be made. For syn-
chronous control of several TWIST-52LED moving
heads via the same DMX addresses, this proce-
dure is used e. g. to minimize deviations in the
direction of the light beam.
1) Keep the button ENTER (4) pressed for approx-
imately 2 seconds until the display changes to
show Pan Offset.
2) Press the button MENU,
required function:
Pan Offset fine adjustment
0 ... 255 for the pan of the head
