IL-2 Sturmovik

IL-2 Sturmovik Telemetry Source Setup

Connection Method

UDP — IL-2 Sturmovik sends telemetry data over UDP via its motion device and telemetry device interfaces.

• Default IP: 127.0.0.1

• Default Port: 20888

Setup Steps

To enable telemetry output, edit the game's data/startup.cfg file and add the following two sections:

[KEY = motiondevice]
    addr = "127.0.0.1"
    decimation = 1
    enable = true
    port = 20888
[END]
[KEY = telemetrydevice]
    addr = "127.0.0.1"
    decimation = 1
    enable = true
    port = 20888
[END]

Using alongside other telemetry software

If you use another application that also uses IL-2 telemetry data (like SimShaker), you can output to both the DRSM port and the default port 4321:

[KEY = telemetrydevice]
	addr = "127.0.0.1"
	addr1 = "127.255.255.255:20888"
	decimation = 1
	enable = true
	port = 4321
[END]
[KEY = motiondevice]
	addr = "127.0.0.1"
	addr1 = "127.255.255.255:20888"
	decimation = 1
	enable = true
	port = 4321
[END]

Available Telemetry

• Orientation: Pitch, Roll, Yaw

• Acceleration: Full 3-axis acceleration

• Angular Velocity: Rotation rates

• Speed: Airspeed

• RPM: Engine RPM

• Altitude: Above ground level

Telemetry Quality: ★★★★☆

Recommended Starting Settings

• Primary Cue Gain: 60–90%

• Smoothing: Low to medium

• Washout: Medium

Known Quirks

• Both motion and telemetry devices needed: IL-2 has separate motion and telemetry data streams. Both sections must be added to startup.cfg for full telemetry coverage.

• Decimation: Setting decimation = 1 sends every physics frame. Higher values skip frames.

Troubleshooting

No telemetry data

1. Verify both [KEY = motiondevice] and [KEY = telemetrydevice] sections are present in data/startup.cfg.

2. Ensure enable = true is set in both sections.

3. Check that the port matches DR Sim Manager's listen port (default 20888).

4. Make sure you are in a mission flying an aircraft.
