NOTE: This block was removed in Refined Storage 1.7. This block will return later in an addon mod.
A Writer has the ability to manage Reader / Writer channels on a network.
The Writer is a block that exposes items, fluids, energy and / or a redstone signal from the bound channel. The data that is received is sent from the Reader.
The Writer doesn't auto-push any of the supported types (with an exception to redstone signals). You have to extract it manually.
