-Setting PWM Frequency:
-“S1FXXXT”: set PWM1 frequency as XXX HZ (001~999)
-“S1FXX.XT”: set PWM1 frequency as XX.X KHZ (00.1~99.9)
-“S1F:X.X.X.T”: set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)
-“S1”: PWM1
-“S2”: PWM2
-“F”: frequency
-“D”: duty cycle
-“T”: stop sign bit
-Setting PWM Duty Cycle:
-“S1DXXXT”:set PWM1 duty cycle as XXX；(001~100)
-“S2DXXXT”:set PWM2 duty cycle as XXX；(001~100)

Parameter Setting:
-The module has a 3-channel key: Set, Up, Down
-By short press SET key,can shift display 4 parameter values (FR1:PWM1 frequency;dU1:PWM1 duty cycle;FR2:PWM2 frequency;dU2:PWM2 duty cycle);before shifting,there will be corresponding parameter name flashing
-Directly press UP, DOWN key to modify the current parameter value
-2-channel PWM is set 3 kinds frequency value, in frequency display interface, by long press SET to shift,3 kinds frequency’s duty cycle is the same （XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz; X.X.X.:1Khz~150Khz).
