If you are using a standard DMX controller, you can connect the DMX output of the controller directly to the DMX input of the first unit in a DMX chain.
Always connect the output of one unit with the input of the next unit until all units are connected.
At the last unit, you must close the DMX line with a terminating resistor. Take an XLR connector and solder a 120 Ohm resistor
between signal (-) and signal (+) and connect it to the DMX output of the last unit in the line.
The LEDs can be switched on with the button ON and switched off with the button OFF.
Use the buttons and to adjust the brightness for the static colours or speed in program mode.

The remote control is supplied with a battery inserted. An insulating foil between the battery and the battery contacts prevents the
battery from being discharged during storage. Prior to the first operation remove the foil from the battery support on the rear side of the
remote control. Otherwise operation of the remote control is not possible.
If the range of the remote control decreases, replace the battery. For this purpose, on the rear side of the remote
control press the small bar with the groove to the right (1) and at the same time remove the battery support (2). For
operation, one 3 V button cell type CR 2025 is required. When inserting, pay attention that the positive pole of the
button cell shows upwards in the support.
