I'm sorry that nobody ever answered your question.
Yes you need a resistor or you can burn up your motor(s).
The resistor goes across pins 1 & 5 - those are the 2 on the ends of the long side of a DB9 connector. The long side has 5 pins, the short side has 4 pins.
The resistor value is driven by the amperage of your motor. In this case, you will need a 2.8k ohm resistor (1/4 watt is fine).
Finally, the resistor is to be place on the connector that plugs into the Gecko G540.
Hope this helps,
P.S. Your English is fine - no problem understanding your question.
