P2P¶

The big one, if you want to move a lot of Channels in a single cable.

---

Portals¶

You can essentially imagine two P2P Tunnels as Portals that connect to each other.

As you can see, the Cable coming from the Controller retains all Channels used on it when traveling through the P2P, but the cable actually holding the P2P Tunnels only uses two Channels.

P2P Subnets¶

Without a Controller, you’ll only have 8 Channels available on the cable connected to the P2P Tunnels. For you to be able to have 32 P2P Input Tunnels and 32 P2P Output Tunnels, you’ll need a Controller.

Now while this looks almost identical, the difference is pretty significant. You now have 32 Channels per Controller face, each of which being able to hold 1 P2P Tunnel for a total of 32 P2P Tunnels per Dense Cable.

32 x 32 Channels¶

In this example, we have 32 P2P Tunnels connected to the controller on the left and then another 32 P2P Tunnels connected on the right. Each Colored Cable on the right gets their Channels from the Controller, so we’ve essentially just moved 1024 (32 x 32) Channels in a single Dense Cable. (Technically two Cable cause of the Controller in the middle)

Linking up P2P¶

To connect two P2P Tunnels, you have to use the Memory Card. P2P Tunnels have specified Inputs and Outputs, they are not bidirectional. The Input is generally on the Controller.

Other P2P’s¶

P2P doesn’t just exist for channels they also exist for a lot more things, with addons adding their own types.

You can transform normal P2P Tunnels into different versions, by using a specific item. You can check what Item by pressing U or Right-Click on the item in EMI.
