Parameter Setting:

Module has 3-channel key:Set,Up,Down

1. 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

2. Directly press UP,DOWN key to modify current parameter value

3. 2-chhannel PWM are set 3 kinds frequency value, in frequency display interface,by long press SET to shift, 3 kinds frequency's duty cycle are the same (XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz;X.X.X.:1Khz~150Khz)

Setting PWM Frequency:

1."S1FXXXT": set PWM1 frequency as XXX HZ (001~999)

2."S1FXX.XT": set PWM1 frequency as XX.X KHZ (00.1~99.9)

3."S1F:X.X.X.T": set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)

4."S1": PWM1

5."S2": PWM2

6."F": frequency

7."D": duty cycle

8."T": stop sign bit

Setting PWM Duty Cycle:

1."S1DXXXT": set PWM1 duty cycle as XXX(001~100)

2."S2DXXXT": set PWM2 duty cycle as XXX(001~100)

Setting successfully back: DOWN

Setting unsuccessfully back: FALL
