What is it?

Don't you just hate it when you accidentally connect the red circuit wires belonging to 2 outposts to the same pole and thus messing up your logic?

Finternet to the rescue! Finternet is kindof like the Internet (hence the name), or at least a WAN (Wide Area Network). It sends your data in very short bursts and attaches addresses to it. This way you can have dozens of nodes connected to the same red wire network without getting any data corruption.

How to install

1. First plop down the Bus Controller somewhere and connect the medium power pole to your red circuit network. You only want to install one controller, otherwise it'll mess up your system.
2. Then place a Finternet Node wherever you have to send and/or receive data or a Receiver Node if you only want to receive data.
3. Configure your node. You need to give it a unique address. This is very important. In every node blueprint, there is one concrete tile with a constant combinator on it. The Y variable represents the address of that node and should be changed to something unique.
4. Connect the red wires of the TX and RX poles to the rest of your network. You're now linked up and ready to send and/or receive.
5. Connect the red wires of the IN or OU poles to your own circuit logic. IN means data goes into the node (that's the data you want to send) and OU means data that comes out of the node (that's what you receive from somewhere else).

If you want to test the system, place the Node + dummy input + output memory blueprint over the Finternet Node blueprint and forget about step 5, I already did that for you. Turn on the constant combinator with the green signal to send something.

How to send data

You can use any signal, positive or negative, except for the yellow and green signals. Also be very careful with the R signal because that is used to determine the receiving node.

The Finternet Node accepts a burst of at least 1 tick or a continuous signal as input. Do note that only the first 1 or 2 ticks of input are sent. Everything after that is ignored until the node has sent its data. The node starts working as soon as data is detected on the red wire. A continuous signal is only sent once, unless it changes.

In order to get your data at the right location you can set the R variable as the address of the recipient. If the recipient is always the same you can set this variable in the variables constant combinator (the one on the concrete where you set the signal). If you set the signal here it will act as a default so if you send an signal along with your data it will use that one instead.
