RedNet Cable Signal Help

[MCKerrnel]

I recently posted this as a bug but was told this was intended rednet behavior, which I can't fathom. Unfortunately the thread was closed, so I couldn't follow-up. Scenario A was from before I posted the bug. Scenario B was what I did as a result of the above communication.

A) Rednet cable with lever on it, white, forced -> rednet cable -> Rednet cable, white, forced to t5 soul shard. When lever is ON, spawner turns off. When lever is OFF, spawner turns on.

B) Rednet cable with lever on it, white, forced -> rednet controller inverting signal -> Rednet cable, white, forced to t5 soul shard. When lever is ON, spawner is off. When lever is OFF, spawner turns on.

The problem is that when the server resets, in BOTH situations, the spawner doesn't receive a signal. There is a chunk loader keeping the area (and surrounding chunks) loaded. Scenario A I can sort of understand. Scenario B I have no idea why this isn't working. The lever is off, there is no signal on the input cable, so the controller should be inverting it by default to turn the spawner off.

Is there something I'm missing? This doesn't make much sense. If I put a lever directly on the spawner, obviously, it works as intended.

Sounds like the PRC isn't rebooting properly. Try using a redstone torch beside the spawner, so when the lever sends a signal down the cable, it supresses the torch and lets the spawner run.

To put a redstone torch next to the spawner would require a redesign of the entire system.

What is the PRC?

I had exactly the same problem, apparently to do with rednet cable losing its 'on' state on server restarts. The suggestion proposed as a fix was sticky pistons and redstone blocks at the spawner side of the rednet cable, which would also require a redesign. This issue was happening to me outside of the spawner situation so definetely rednet / server restart derpiness.

This would seem to defeat the purpose of the rednet cable if we had to resort to vanilla means to effect the same result?

Am trying right now to use wireless, but having issues getting them to work since we don't have redstone wire anymore. Cable is the only real solution to vertical placement but if it resets the signal requiring a toggle every server restart, that's not very helpful.

I don't know if the problem you and I were having is the same but I had a problem with some but not all industrial steam engines not starting upon turning the game off and on. I solved the problem by making a small computer program that runs on startup and it goes something like

sleep(3)
redstone.setOutput("some side", true)

and then it is as if a player walks in to my boiler room and manually turns each engine on. Maybe you could do something similar.

PRC is Programmable Rednet Controller. You can plug that into the system, and set it up like the logic gates from Red Power. For example, cable 1 into the left, and cable 2 out the right. Then set it as Nor (2-Input). Set the left side to I/O L, and the right side to I/O R. Then a signal turned on to the left turns off the outgoing right cable.

Does your cable go up at any point? If so then you could probably put a redstone torch there to generate the positive signal, into the further cable, and turn it off when the new signal comes in. That should do the job as well.

What does the design look like? I have trouble imagining one that doesn't have room for a torch.

Unfortunately this is currently an issue with rednet. It doesn't reset to it's proper state on restarts sometimes which causes all kinds of issues.
