Well i am not familiar with LISA but i checked your files and they look correct.
One thing to try is to change the polarity from POSITIVE to NEGATIVE maybe your encoder outputs a negative ppm wavetrain and to lower the sync_min from 5000 to say 3000 just in case.
".....sync_min="5000" sync_max="15000" pulse_type="POSITIVE">"
Since you checked the encoder's output then either the signal does not reach the Autopilot (bad wiring?)
or the polarity is wrong or the ppm encoder does not output 8 channels as the autopilot expects
by using your radio file (far fetched).
