Power Bar
The Power bar is the LED Wall component for the distribution of data and power. It is located at
the bottom of the LED Wall and connects to each row of modules via the Network and power
supply socket. The Power bar also serves as cable conduit: The cables for power supply and
data transmission run inside the Power bar from Hub boards and the terminals to the exit
points on the back of the Power bar.
