[maxmsp] max > servo controller SSC-32

hi,
IŽm trying to run servos, from max 4.6 to the servo-controller,
with USB/serial switch.
I get the green light blinking, but cannot fix the code/number typed in which moves the servos:
datasheet for the controller:
Servo Move Example:"#5 P1600 S750 <cr>" 

this ist what makes the green blinking, but not more:
who can help me please?
