LED LIGHTBAR 4TC
Electrical installation for two or more units in master/slave:
Connect 2 to maximum 16 units together using good quality balanced microphone cables. The first unit
in the chain will automatically act as master, the other units will act automatically as slaves.
Make sure that all units are connected to the mains.
Done!
Remark:
You can connect a CA-8 or CA-32F remote controller to the master unit if you want to have more
control over the master/slave operation
Electrical installation in Master/slave-mode with the LEDCON-02 remote:
Up to 42 LED LIGHTBAR 4TC units can be daisy chained and connected to the output of en optional
LEDCON-02 remote using a good quality balanced cable.
All connected units are automatically switched as slaves.
IMPORTANT REMARK:
to make sure everything works well you MUST set the LED LIGHTBAR 4TC
in “LEdC” channel mode and perform the “automatic address distribution” feature on the LEDCON-
02 before using the set for the first time!!! (check the user manual of your LEDCON-02 to see how
this is done)
Electrical installation 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.
Both XLR-3pin and XLR-5pin connectors are used, however XLR-3pin is more popular because these
cables are compatible with balanced audio cables.
Pin layout XLR-3pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+)
Pin layout XLR-5pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+) ~ Pins4+5 not used.
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.

LED LIGHTBAR 4TC
HOW TO SET THE RIGHT STARTING ADDRESS:
Refer to the previous chapter (DMX-512 address setting) to learn how to set the starting address on this unit.
The starting address of each unit is very important. Unfortunately it is impossible to tell you in this user
manual which starting addresses you have to set because this completely depends on the controller you will
use… So please refer to the user manual of your DMX-controller to find out which starting addresses you
must set.
DIFFERENT DMX-CONFIGURATIONS OF THE LED LIGHTBAR 4TC:
1 CHANNEL AND 1MSL MODE:
1CH MODE:
only 1 DMX channel is needed to select the internal shows. The shows will run to the
rhythm of the music when “sound mode” (see earlier) is set to on.
1MSL MODE:
the same functionality as 1CH mode but you can connect several LED LIGHTBAR
4TC as slave. They will all show exactly the same patterns as the master. (in this case no other
DMX-units than LED LIGHTBAR 4TC can be put in the same DMX-line)
4 CHANNEL MODE:
The 4 projectors of the unit will react exactly the same way as any of the other JB SYSTEMS LED-
projectors while they are switched to 4CH mode.
