I am not quite sure what is the word mean for calibrate the RailDriver. I got the program from the site in Germany and it's a payware program.
The first thing to do is to calibrate the RailDriver and here is the message below.
Please move the bailoff lever to the bottom right and confirm this with OK.
Now you see what is the bailoff lever is? I am not sure myself to start calibrating the RailDriver with that software, RDTrain Fix 1.6
Maybe you know what is the bailoff lever for RailDriver?
