How does aux channel work in Pixhawk?

I have a gimbal that the I need to radio control for pitch with channel 9 on my radio… I was so impressed that the Pixhawk had those 6 aux channels (#1 being ch 9)… Using a servo for testing I can’t get it to move off center either manually or by RC… In parameter list I have gone to RC9 and changed it to pass-thru without success… I don’t know if this is an issue with the code, pixhawk ,MP or me…

futaba 6203, tf8g
pixhawk 2.4
Mp 1.2.93
3.1.1rc1

Thanks for any help
