ELECTRICAL INSTAL ADDRESSING
Important: The electrical installation should be carried out by qualified personal only,
according to the regulations for electrical and mechanical safety in your country.
•
Gently unscrew the plastic dome from the plastic base
and separate both parts.
•
Place the plastic dome in a safe place so it won’t be
damaged during the installation.
•
If the LED BALL is used with one of the optional
adapters, make sure the base is mechanically well
fixed before you start connecting the electrical wires.
•
Especially when the unit is installed outdoors, you
should use suitable cabling that withstands the
weather conditions in your country (rain, sun, heat,
cold, …)
•
On the base you will see 3 cable entry glands that
make it possible to make waterproof connections.
Feed the cables from the outside through the cable
entry glands.
•
Strip the cables and connect them to the
corresponding contacts. Please check the picture to
see the different possibilities:
A. Mains contacts:
connect the mains power cable to the N and L contacts (100V~240V 50/60Hz).
Since the complete unit is made of plastic, you won’t find a ground connection. However you can
connect an eventual ground wire to the dummy contact, next to the L contact.
B. DMX input contacts:
use the DMX in/out contacts when you want to
control the unit by DMX or if you want to connect several units together
in master/slave mode. In most cases you will have to connect the 3
contacts to a male XLR cable-connector. The numbering on the contacts
of the unit correspond to the numbering of the contacts on the XLR-
connector.
C. DMX output contacts:
use the DMX in/out contacts when you want to
control the unit by DMX or if you want to connect several units together
in master/slave mode. In most cases you will have to connect the 3
contacts to a female XLR cable-connector. The numbering on the
contacts of the unit corresponds to the numbering of the contacts on the
XLR-connector.
D. CA-8 remote controller:
use the CA-8 contacts when you want to use the unit in stand alone and/or
master/slave mode. In most cases you will
have to connect the 3 contacts to a female
stereo 6.3mm JACK cable-connector.
Check the drawing to see how the contacts
must be wired.
•
Contact 1:
jack connector ground.
•
Contact 2:
Tip of the stereo jack.
•
Contact 3:
Ring of the stereo jack.
•
When all cables are well connected, you must tighten the cable entry glands so the cables are fixed and
the unit is waterproof!
Remark:
You don’t have to use connectors when the unit is used in a fixed installation. However we strongly
suggest to use XLR & JACK cable connectors when the unit is used in mobile applications. (mobile DJs,
hiring companies, …)
Electrical installation for 1 standalone unit:
•
Just install the mains cable (refer to point A)
Remark:
You can connect a CA-8 remote controller to the unit if you want to have more control. Refer to
section “D” to learn how to do this.

Electrical installation for two or more units in master/slave:
•
Connect 2 to maximum 16 units together using good quality balanced microphone cables (like for
example JB Systems MC-01 cable). Refer to sections “B” and “C” to learn how to connect the units
together. The unit that has no cable connected to its DMX-
input will react as “master”, the others are the slave units.
•
Make sure that all units are connected to the mains.
•
When all units are connected together and switched on, you
still have to address all units to obtain nice multi channel
chases. To do this, open the first unit (“master” unit) by
unscrewing the dome from the base. On the inside of the base
you will see the address button, indicated with “F” on the
picture.
•
Press the address button once. All units will switch off and on
again to indicate that the addresses are set.
•
Close the master unit again.
•
Done!
Remark:
You can connect a CA-8 remote controller to the master unit if you want to have more control
over the master/slave operation. Refer to section “D” to learn how to do this.
Electrical installation for two or more units in DMX-mode:
•
The DMX-protocol is a
widely used high speed
signal to control intelligent
light equipment. You need
to “daisy chain” your DMX
controller and all the
connected units with a good
quality balanced cable (ex.
JB Systems ref. MC-01).
Refer to sections “B” and
“C” to learn how to connect
the units together.
•
To prevent strange behavior of the light effects, due to interferences, you must use
a 90
Ω
to 120
Ω
terminator at the end of the chain. Never use Y-splitter cables, this
simply won’t work!
•
Make sure that all units are connected to the mains.
•
Each light effect in the chain needs to have its proper starting address so it knows which commands
from the controller it has to decode. In the next section you will learn how to set the DMX addresses.
How to set the DMX addresses:
There are 2 ways to set the DMX-address of the units:
A. Automatic DMX-addressing:
To save a lot of time (imagine the time it takes to set the
DIP switches of 16 units…) you can set the DMX
addresses of all units in the DMX-chain just by the push of
a button. No need to calculate the starting address of each
individual unit, this will be done for you!
•
Make sure the DMX cables of all units are connected.
•
Connect all units to the mains so they are switched on.
•
Open the first unit in the DMX chain by gently
unscrewing the dome from the base. On the inside of
the base you will see the “address button”, indicated
with “F” on the picture.
•
Press the “address button” once. All units will switch off
and on again to indicate that the addresses are set. Please note that the first unit in the DMX-
chain always receives DMX-address 001. Since each unit uses 4 DMX-channels, the 2nd unit has
start address 005, the 3rd has address 009, the 4
th
has address 013, … etc.
•
Close the first unit again.
•
Done!
