Pin 4 and pin 5 are not connected. For RJ11
plugs: pin 1 = +12V, pin 2 = DATA+, pin 3 = DATA­
, pin 4 = GND.
Connect the signal coming from the controller to
the DMX socket of the unit labeled DMX IN.
Continue connecting the DMX OUT socket to the
DMX IN socket of the next unit.
Termination of the DMX signal
For installations where the cable signal must
travel long distances or where there are electrical
noises, for example a discotheque, it is
recommended to use a DMX terminator. The DMX
terminator is simply an XLR connector with a
resistance of 120Ω (Ohm) between pins DATA­
and DATA+. The connector is then plugged into
the DMX OUT socket on the last device in the
chain.
Analog input
The dimmer pack can also be controlled via an
analog 0­10V dc control signal. The input socket
for this analog signal is located in the front panel
of the unit and uses a DB­9 female connector.
The six control values are connected to pins 1 to
6 through a DB­9 male flying connector.
PROJECTOR ADDRESSES
The unit, to be remotely controlled, requires 6
DMX channels. Each dimmer pack must be given
a digital start address number so that the correct
unit responds to the correct control signals. This
digital start address is the channel number from
which the unit starts to “listen” to the digital control
information being sent out from the controller. This
digital encoding must be done on each unit.
The start address of the coding is assigned by
setting the desired value using the display
interface on the front panel.
Press and hold the
DMX button on the keypad,
then use the ▲ or ▼ buttons to select the desired
starting address (ie. dimmer 1 address 1
D.001
,
dimmer 2 address 7
D.007
, dimmer 3 address 13
D.013
, etc.); for fast forward press and hold the
button.
OPERATION
After supplying the device, the software performs
a reset; at the end of the electronics reset routine,
the display shows the idle state.
In the idle state the following informations are
shown:
d.001
d001
is the base address of the dimmer pack.
. (blinking dot) indicates the presence of a valid
DMX signal.
In the absence of DMX signal (XLR connector
unplugged), the blinking dot is off.
Set the base address of the unit as seen before
and connect the signal from DMX controller to
control the intensity of various lighting fixtures
connected.
