The data sheets for MDrive23 are rather quiet on the subject of comm settings, which is a surprising deficiency, but from the SE Knowledge base :
The baud rate is configurable in the motor, so you may need to try non-default settings if you didn't get the motor new in box.
Dare I ask how much these motors cost?
