Power Injection Query

[Dreamin]

Hi Everyone.

I picked up my set up second hand. I have an F16V3 with 4 smart receivers. The small boxes with the receivers are at the front of my house and the F16v3 maincontroller is at my front door and does my roof and mega tree.


photo above, as you can see unused V- and V+ port.

In the box the smart controller is set up with power to the smart controller and network. The 4 ports are 2 with data, and 2 with power injection. I have 4 mini trees with stars, some globes, and arches, and candy canes all down on one box so would rather spread it over 4 ports (limited to 200 each port).

So can I change the 4 ports to full data and pull some power out the unused port and create some separate power injection ports? I'm running 5V so I'm going to need power injection. I'm already seeing some flickering on lights (which I have assumed is power injection issues). I read somewhere that it's ok to do this but you have to combine the ground wires? If they are going back to the same power supply (but a different port) does that matter?

TIA

I hope you have something to insulate the back of the smart differential board from short circuiting against the metal power supply.

Those 4 ports can all do data and power.
If power injection is needed you can use power from an used/unused output port (which is protected by the orange fuse) or have a new wire from the power supply.
I would have another wire from the power supply for power injection. Have a fuse like you have added between the supply and the receiver.

No matter what, GND/black wire/grounds need to be connected together.

There is plenty of resources already on power injection topic.

The smart board is hung from some clips so spaced from the power supply but still not to my liking. I'm going to remove it and 3d print a bracket so it's easier to get into.

I'll have a look around for some more info in power injection but it sounds like I was on the right track. It's a 30A PSU so should have enough omph. Thanks.

3D printed a proper falcon smart board with an enclosed back. I’m going to swap these out into a different Bunnings enclosure and wire an extension a cord right into the PSU. No room for my fingers in this one and my patience is wearing thin with 2 kids and a wife home.
