8. Operation via DMX
8.1 Preparation
According to the DMX standard, no more than 32
DMX devices (with separate power supply) should
be connected to a DMX signal. Then the DMX sig
-
nal must be amplified with a repeater. To supply
the bus, a supply voltage of 12 - 24V DC must be
present (current consumption per module <7mA).
If your controller has a masterfader or overall vo
-
lume control, make sure that the DMX value 255
(Max. Level) is adjustable, otherwise no program
-
ming can be performed.
A value from 1 to 512 can be assigned as start
address. In the delivery state, the start address (of
the device) is preset to 1. The module uses one
DMX channel.
For example, perform a factory reset:
Press one of the two buttons (device button
or push button
,
after 20 seconds the LED il
-
luminates for 2 seconds, which shows phase 1.
Hold the button pressed in, phase 6 is followed by
a slightly longer pause until phase 7 is activated.
During these 2 seconds of the activated phase the
push button must be released.
The dimmer is now reset to the factory settings.
To operate a device with DMX, a DMX512 control
-
ler is required. A gateway can also be used to crea
-
te an interface to other protocols such as KNX...
A supply voltage of 24V DC must be available (cur
-
rent consumption per module <7mA). Within the
DMX protocol, a correct clamping of the signal line
with + 24V and -GND must be ensured.
NOTE - Before operating the dimmer, it is
necessary to send a DMX signal once. As
long as the DMX input is used (DMX signal
is transmitted), the device button and
push button inputs are not active. One se
-
cond after the last DMX signal has been
received, the button inputs are reactivated
again.
