# Test Drive Unlimited Solar Crown

## Connection Method

**UDP** — TDU Solar Crown sends telemetry data over UDP.

* **Default IP**: `127.0.1.1`
* **Default Port**: `20777`
* **Default Rate**: 120 Hz

## Setup Steps

1. Locate and open the file `UserSettings.cfg` found in:

   ```
   C:\Users\<UserName>\Documents\My Games\Test Drive Unlimited Solar Crown\
   ```
2. Modify the following settings:

   ```plaintext
   Rc2.Telemetry.TelemetryPort = 20777;
   Rc2.Telemetry.TelemetryAdress = "127.0.1.1";
   Rc2.Telemetry.EnableTelemetry = true;
   Rc2.Telemetry.TelemetryRate = 120;
   ```
3. Save the file.
4. Launch Test Drive Unlimited Solar Crown.
5. In DR Sim Manager, select **Test Drive Unlimited Solar Crown** and click **Start Motion**.

## Available Telemetry

* **Orientation**: Pitch, Roll, Yaw
* **Acceleration**: G-forces
* **Speed**: Vehicle speed
* **RPM**: Engine RPM

### Telemetry Quality: ★★★☆☆

## Recommended Starting Settings

* **Primary Cue Gain**: 60–90%
* **Smoothing**: Medium
* **Washout**: Medium

## Known Quirks

* **IP address**: Note the IP address is `127.0.1.1` (not the usual `127.0.0.1`). This is specific to TDU Solar Crown's telemetry implementation.

## Troubleshooting

### No telemetry data

1. Verify `UserSettings.cfg` has `EnableTelemetry = true`.
2. Check the IP and port settings match.
3. Make sure you are driving (not in menus).
4. Restart both the game and DR Sim Manager.
