The manual's description about Pixhawk 4's I/O PWM Out to Power Management Board's I/O PWM In and FMU-PMW-in is confusing.
Suppose I have Main 1-4 Mapped to servos, Main 5, 6 mapped to motors in PX4. According to the table above, I need:
I/O PWM Out -->I/O PWM IN to enable the motors
I/O PWM Out -->FMU PWM IN to enable the servos
Do I need a Y wire to connect pixhawk4's I/O PWM Out to both PMB's I/O PWM In and FMU-PWM-In?
And use PMB's FMU-PWM-out 1-4 for servo, and PMB's M5 and M6 for motor?
If I misunderstand the table, please state out too.
If you don't know what I am talking about, you may just simply show me how you connect the Pixhawk and PMB for an standard plane like aircraft which has both motors and servos in MAIN channels. That would help me.
Thank you very much!
