Master/Slave-operation
The master/slave-operation enables that several devices can be synchronized and controlled by one master-
device.
On the rear of the LED THA-50F COB 3200K theater spot you can find an XLR-jack (DMX Out) and an XLR-
plug (DMX In), which can be used for connecting several devices.
Choose the device which is to control the spotlights. Set the desired Master-mode on the master-device.
This device then works as master-device and controls all other slave-devices, which are to be connected to
the master-device via a balanced microphone lead. Connect the DMX out connectors with the DMX input
plug of the next device.
Set the Slave-mode on every slave-device.
DMX-controlled operation
The device has 2 DMX channel modes. The Control Board allows you, as described above, to assign the
DMX-Mode.
You can control the devices individually via your DMX-controller. Every DMX-channel has a different
occupation with different features.
The Control Board allows you to assign the DMX fixture address, which is defined as the first channel from
which the LED THA-50F COB 3200K theater spot will respond to the controller.
Please, be sure that you don’t have any overlapping channels in order to control each LED THA-50F COB
3200K theater spot correctly and independently from any other fixture on the DMX-chain. If several LED
THA-50F COB 3200K theater spot are addressed similarly, they will work synchronically.
If you set, for example, the address to channel 4, the device will use the channel 4 to 6 for control.
Controlling:
After having addressed the LED THA-50F COB 3200K theater spot, you may now start operating it via your
lighting controller.
Note:
It’s necessary to insert the XLR termination plug (with 120 Ohm) in the last lighting in the link in order
to ensure proper transmission on the DMX data link.
