I'm New Here
I have installed a GRT SportSX and Trio Pro Autopilot with Airinc429 adapter and need help testing, configuring, and comfriming my installation is correct.
The Trio AP alone seems to test okay, The TRK and ALT HLD lights illlumnate on power up after entering the field alt. The GPSS illuminates but the GPSV (only blinks) for some reason does not. The HNAV and VNAV lights illuminte when engaged.The control sticks respond correctly when their respected servo is tested in the configuration menu or in CRS mode and inputing left or right of the course.
The EFIS flight Director responds in the horizontal modes such as HDG and ENAV (from a VOR course). The Vertical mode accepts a new altitude, but VS window does not change, always shows +300 below the altitude status on left side of EFIS display
My first question since I am not using a GRT A/P, what is the proper way to engage the AP to be controlled from the EFIS? I don't see any engage soft keys that the GRT AP manual shows with their AP installed. Do I just select the LAT and or VERT mode and then engage the Trio HVAV and VNAV buttons?
Second question during testing with AP servos engaged, should the control sticks follow the FD commands on the EFIS on the ground?
Third question how do you select "no" mode (Horizontal or Vertical) from the EFIS AP menu, I can only change from HDG to ENAV and such but not select VERT or HORZ mode?
I presently only have been able to feed the AP with Autopilot AVIATION MAP and not NEMA0183 (the EFIS has a built in GPS) and is not showing any NEMA 0183 to the ELT beacon or MVP-50 with those set to receive 9600 baud (these are fed from pin 32 of the SportSX)
Looking forward for any help
