How is the shield combinator supposed to work? I don't get it. It's description merely says that as long as it receives a red signal, any connected shields will stay disabled. But how do I connect the shields to the combinator, and how do I give the shield combinator a signal? Is the red signal supposed to go into the shield combinator, or is the shield combinator supposed to output the red signal? Nothing I've tried seems to work.
Also, the turret shield toggle item, it doesn't seem to work either. It just activates a small symbol on the turret, but the shield is still operational.
Are these things implemented? Or am I missing something.
