avoid cumbersome wiring. The PPM indicator lamp will light up when the valid PPM
signal is detected.
Note:
PIN13 can input PPM containing 14 channels of data, while the the PPM
signal rate should be larger than 30Hz. Moreover, the PPM content should be
more than 4 channels of data, otherwise it will be considered as invalid signal or
error signal.
PIN14 is SBUS input. If you have receiver like R6203SB, you can use single
terminal such as PIN1,PIN2,PIN14 to forward 18CH. If a valid SBUS signal is
detected, SBUS LED will light up.
PIN27 is the IDLE control terminal of the transmitter. The input signal is PWM
signal. When the input pulse width more than 1.55 milliseconds, T4047NB20
transmitter will move to IDLE mode with no signal to be transmitted and IDLE LED
will light up. When the input pulse width is equal or lesser than 1.55 ms, T4047NB20
will keep transmitting with the previous frequency. If there is no signal on PIN27 ,
then there is no operation.
PIN28 is the IDLE control terminal of the transmitter. The input signal is logic
signal. If there is no load, then no operation will be conducted,and the transmitter will
be in the normal mode. When there is short circuit to GND, the transmitter will move
to IDLE mode with no signal transmitting,and the IDLE LED will light up. When
there is open circuit to GND, the transmitter will move to normal mode.
Note:
When input a mixed-signal, the PWM signal has priority over PPM, and
PPM has priority over SBUS.
For example, when SBUS and the PWM input at the same time, the
corresponding servo signal of SBUS will be replaced by PWM signal and then be
transmitted.
When there is no data input, the signal acquisition system will not output
data and the fault LED will light up . When there is any valid data input through
PWM \ PPM \ SBUS, the signal acquisition system will output data stream, and
the data output LED will light up.
If the input signal is lost, the other channels besides CH3 and CH13 will
transmit 1.5mS signal automatically. And the CH3 and CH13 will transmit
1.1mS signal.
WARNING: Please correctly set ESC or the engine throttle control direction.
1.1 ms means engine cut. This is opposite to the default direction of FUTABA
radio. If it is set incorrectly, the motor may suddenly start up under failure
