#### Decoder topology
| Role | Physical placement | Example decoder IP | AMMC WS port | Effect |
|---|---|---:|---:|---|
| Main start/finish | Start/finish loop | `192.168.1.10` | `9000` | Counts laps and controls lap time |
| Split | Intermediate loop | `192.168.1.11` | `9001` | Records split from the latest main crossing; never counts a lap |
| Pit entry | Entry to pit lane | `192.168.1.12` | `9002` | Opens a pit stop |
| Pit exit | Exit from pit lane | `192.168.1.13` | `9003` | Closes and times a pit stop |
The decoder IP and WebSocket address are different things. The decoder IP points from AMMC to physical hardware. The browser connects to AMMC on the backend host, for example `ws://192.168.1.100:9001`. Each decoder must have a unique network address and each AMMC process must have a unique WebSocket port.
Use only the channels physically installed at the track. One decoder on `9000` remains the default and needs no optional settings. Split timing requires one additional decoder. Pit timing requires two additional decoders because entry and exit are separate events. A complete setup therefore uses four decoders.
1. Place AMMC binaries in the `AMMC/` project folder.
2. Open `Settings`.
3. Enable `Managed AMMC`.
4. Set `Decoder IP / host`, verify port `9000`, save.
4. Set the Main `Decoder IP / host`, verify port `9000`, and optionally enable/configure Split and Pit channels from the table above.
5. Click `Start AMMC`.
6. Click `Use server WS URL` so the client uses for example `ws://<server-ip>:9000`.
