URM37 ultrasonic sensor MOTO pin?

Hello everybody,

I've got an ultrasonic sensor URM37 v3.2, and it has a moto pin to do something with a servo. I can't seem to find what it can do and how I need to use it. Does anybody know how it works?

I have this servo: http://www.servodatabase.com/servo/feetech/fs5103r It's a 360 degree continuous servo..
