HOW TO CONFIGURATION GEAR RATIO IN MDC2640?

I use encoder 1000 pulses/rev, Motor have gear ratio 1:34.
If the motor turns 1 round, the encoder turns 34 turns.
So, how to configuration gear ratio in RoboRun+ ?
Thank you !

I answered your question in another thread, but you should just input the resolution as 1000 PPR.
