I bought recently the LED strip WS2813 ( http://www.normandled.com/upload/201605/WS2813%20LED%20Datasheet.pdf ).
I use a DC 5V 20A power supply.
I soldered the V+ output to the +5V entry of the LED strip, and the ground to the ground. I did not connect anything yet to the DI/BI.
I measured voltage between V+ and V- and it's correct (5V). However, the LED strip do not light up.
The question is: Do I need to send the signal to the DI/BI to expect something, or should it shine some light already ?
I have read that some model DO light without the controller, but I did not find anything on this specific model.
I have a raspberry pi that I will connect, with Hyperion to control the LED, but I would have expected the LED to already have done something by now.
