Specification:
Item Type: Signal Generator Module
Material: Plastic
Frequency range is divided into four, automatic switching:
1.XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz;
2.X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz;
3.XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz
4.X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz
e.g. frequency display: 100 indicates that the PWM output pulse of 100Hz;
1.01 represents the PWM output pulse 1.01K;
54.1 represents the PWM output pulse 54.1KHz;
1.2.4 indicates that the PWM output pulse of 124KHz;
Duty cycle range: 0 to 100%
All setup parameters, power down save.

1. The PWM frequency
"F101": Set the frequency of 101 HZ (001 ~ 999)
"F1.05": Set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": Set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2. The PWM duty ratio
"DXXX": Set the PWM duty cycle is XXX; (001 ~ 100)
For example D050, set the PWM duty ratio is 50%
3. Reads the set parameters
Send "read" string read parameter settings.
Setting successful return: DOWN;
Setting failback: FALL
