My set up is a Lighting Node Core which has 6 SP120 Pro fans connected to it. The Node Core is attached to the Commander Pro via the USB cable. I just got a RGB LED Lighting Pro expansion kit and with four strips linked I plugged it into the LED 1 plug on the Commander Pro and none of the strips would light up. When I plugged it into the LED 2 plug the strips worked fine.
Now, I know the Commander Pro has just two lighting channels, but since the Node Core is lighting the fans, should I technically have three lighting channels? You know, one run by the Node Core and two more by the Commander Pro? Is the Node Core connected by USB taking up Lighting Channel 1? If so, why can't I control Lighting Channel 1 via the Commander Pro (I can't) and thus can only control it via the Lighting Node Core?
Also, could I pick up a third lighting channel if I were connect the Node Core directly to a USB2 port instead of connecting it to the USB port on the Commander Pro? And if so and as a follow up to that question, I only have one USB2 port, could I use a splitter on the USB2 port and thus get full functionality out of both devices even though they are both going through the same USB2 port?
*EDIT* I just powered down my computer, disconnected the Node Core USB from the Commander Pro, connected the RGB strips from LED 2 and put it in at LED 1 and when powered up the strips functioned as they should. So, point being, there isn't anything physically wrong with the LED 1 port.
