DMX Control

DMX is short for digital multiplex and allows digital
control of several DMX units via a common control
cable. For operation via a DMX light controller (e. g.
DMX-1440 or DMX-510USB from "img Stage Line")
the LED spotlight is provided with 8 DMX control
channels. If required, it can also be controlled via 6,
5, 4 or 3 channels only. The functions of the chan-
nels and the corresponding DMX values can be
found in chapter 10.1.

8.1 Connection

As a DMX interface, 3-pole XLR connectors with
the following pin configuration are provided:
Pin 1 = ground, Pin 2 = DMX-, Pin 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 control input DMX IN (9) to the DMX
output of the light controller.
2) Connect the control output DMX OUT (8) to the
control input DMX IN of the following DMX-con-
trolled unit; connect its output again to the input
of the following unit, etc. until all DMX-controlled
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 control 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.

8.2 Setting the number of DMX channels

The number of DMX channels depends on the
required functions and may also depend on the
number of control channels available on the light
controller. In the 8-channel mode, various internal
show programs are available. In addition, sub-
addresses allow individual control of up to 66
PARL-74RGBW spotlights via 8 DMX channels
only. To select the number of DMX channels:
1) Press the button ESC / MENU repeatedly until
you enter the main menu.
2) Select the option
button UP or DOWN.
in the main menu with the
3) Press the button ENTER: The display shows the
current channel mode:
= 3-channel mode (HSV colour space)
= 4-channel mode
= 5-channel mode
= 6-channel mode
= 8-channel mode
4) Select the desired option with the button UP or
DOWN.

8.3 Setting the start address

For controlling the spotlight set a DMX start
address for the first DMX channel. The other DMX
channels are automatically assigned to the follow-
ing addresses.
Example: Start address 5 for channel 1
– in the 4-channel mode, the channels 2 to 4 are
assigned to the addresses 6 to 8; address 9 is the next
possible free start address for the following DMX-con-
trolled unit.
– in the 8-channel mode, the channels 2 to 8 are
assigned to the addresses 6 to 12; address 13 is the
next possible free start address for the following DMX-
controlled unit.
1) Press the button ESC / MENU repeatedly until
you enter the main menu.
2) Select the menu item
with the button UP or DOWN.
3) Press the button ENTER: The display shows the
current address, e. g.
4) Set the desired address with the button UP or
DOWN.
After setting the start address, it is possible to oper-
ate the spotlight via the DMX controller. When con-
trol signals are received, a dot starts flashing on the
display.

8.4 Using sub-addresses

If you use sub-addresses, you will be able to con-
trol up to 66 spotlights (spotlight groups) independ-
ently from each other via a single DMX start
address. Thus, the maximum number of DMX-con-
trolled units can be considerably higher. The spot-
lights with a sub-address are selected via DMX
channel 8 ( ID table, chapter 10.1.5). To control
all spotlights with a sub-address in sync, set DMX
channel 8 to a DMX value less than 10.
1) Press the button ESC / MENU repeatedly until
you enter the main menu.
2) Select the menu item
with the button UP or DOWN.
3) Press the button ENTER: The display shows
and a number between 01 and 66.
