--- Generic NGP Configuration --------------------------------------------
--------------------------------------------------------------------------

RBR NGP telemetry requires the NGP V6 plugin to be installed (https://www.ly-racing.de/viewtopic.php?t=7878)

Then in game settings file (RichardBurnsRally.ini) enable udp telemetry : 

udpTelemetry=1
udpTelemetryAddress=127.0.0.1
udpTelemetryPort=6776

--- RBR PRO Configuration ------------------------------------------------
--------------------------------------------------------------------------

Concerning RBR PRO you can copy the addons folder inside your RBR PRO installation. 
It will forward the telemetry directly to UDP 6776 without additionnal configuration.
