Pixhwak 4 PM07 board no signal control of servo using RC

I have connected the px4 to pm07 board and also connected 1 servo on FMU-PWM-out 1 pin of PM boar to check if it is working or not. But i can not control it from RC. I used oscilloscope but there is no signal on this pin. But the Futaba receiver shows signal on channel 1 when i move the joystick
