1. set the frequency of the PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
Note: In fine mode, the maximum frequency is 15.0KHz
 
2. set the PWM duty cycle
Normal Mode:
"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
Fine Mode:
"DXX.X": set the PWM duty cycle to XX.X; (0.1 ~ 100)
Such as D20.8, set the PWM duty cycle is 20.8%
 
3. Read the set parameters
Send a "read" string to read the set parameters.
 
4. Modify Mode
MODE0: Normal Mode
MODE1: Fine Mode
Set successfully return: DOWN;
Setup failed to return: FALL.
