Differential Receiver to power inject?

Can I use one channel on my differential receiver to run power/data/ground to a 300 pixel Chroma pole and then use just the power/ground on another channel to power inject? I would like to do this for both chroma poles using all four ports on the differential receiver with one power supply if that makes sense. Total of 600 12v 2811 pixels

I can't talk to the differential receiver since don't own one (yet😬), but how many Watt is your 12V power supply? Because assuming one pixel uses .03 Amps that is 600 x .03 = 18 Amp x 12 V = 216 Watt.  I always like to use 80% of the max capacity of the power supply. Assuming your power supply is 360 Watt (80% is 288) then you should be good there. These numbers would apply at 100% brightness white.

Thank you, they are 360Watts so it sounds like it should work.

Why waste a port for power injection, if you are going to run a wire from the second port to an injection point why not just take the power straight from the power supply or just a power distro board if you want if fused.

Yes it will work.  Just set the port for 1 node.  If you don't need the other port then go for it.

I only have the two props this year with the one differential board on the f48. I built an ammo can with four pig tails and a power supply to put in the yard. For this year, I was thinking this is an easier solution. I do have distro board not being used and I still may go this route if I have the supplies.
