Signal Distributor

The Signal Distributor is an automation building that takes a four-bit input signal and routes it to exactly one of four output ports. It has three inputs: the main Input Signal, plus the Most Significant Control and Least Significant Control inputs that determine which output receives the signal. The selected output sends the original input onward, while the other three outputs are set to red.

Its outputs are arranged in order from the input side outward: Output 3 is closest to the input signal, followed by Outputs 2 and 1, with Output 0 farthest away and next to the LSC input. The control inputs function like a two-bit selector, so the building can choose among four destinations.

The selector logic is:

• MSC red, LSC red → Output 0 receives the input signal
• MSC red, LSC green → Output 1 receives the input signal
• MSC green, LSC red → Output 2 receives the input signal
• MSC green, LSC green → Output 3 receives the input signal

In practical terms, the Signal Distributor is a compact way to split a single automation line into one of several branches without needing a more complex logic setup. It is especially useful when multiple systems share one control source, such as choosing between different machinery lines or routing signals to separate rooms.

A few important notes:

• The building can distribute four-bit signals, not just simple on/off automation.
• Its shown sprite behavior does not exactly match its actual routing behavior; the displayed transmission follows an OR-like appearance rather than the same priority logic used internally.
• Like other automation components, it can be used to build higher-level control systems when combined with ribbons and logic gates.
