Item loaders and unloaders, I didn't test the fluid ones, will only output a redstone signal to vanilla redstone items like dust and repeaters, cannot make them emit into wireless redstone transmitters, project red cables, or zetta industries redstone wires or computercraft computers.

Some pictures. Using version 9.7.0.0

My gui skills are not that great. I should also note that Repeaters work as well.

This is intended, as there is no way to me to possibly whitelist everything, and emitting random redstone near tracks tends to cause strange behaivor.

would it be possible to toggle a side for this? so you can select sides on the gui to emit redstone?
