In order to make IL-2 game to send the telemetry via UDP, insert the two sections in game data/startup.cfg
file below:
Copy [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]
If you use another software that also uses IL-2 telemetry data, like SimShaker, you can instead insert the following code to output to the DRSM port and the default port 4321.
Copy [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]
