its really quite similar to rednet (at least in game) it has the same color coded cables. i think it could work fairly well with the rednet port (or at least you could reuse the gui). It would be great to see support for this

It's a possibility, although I haven't been able to discern exactly what the data range is in EnderIO. Internally it all looks OK.

I noticed that EnderIO already has support for connecting to RedNet cables; it should be pretty simple for the EnderIO team to support other RedNet-connectable blocks too, which would solve this problem in a slightly more elegant fashion. I'll start a conversation with them.

Thanks!

Project Red and RedLogic both constrain their bundled-cable networks to carrying signals in a one-byte value range (0..255). MFR's RedNet allows the full integer range, which BR uses to full effect.

You'll have use redstone ports for Project Red and RedLogic.

While you're at it, is BigReactors, at least in principle, compatible with all incarnations of RedNet, specifically ProjectRed and Immibis' RedLogic, or do these require additional adaptation?
