I am trying to interface an old Aero Sport 6Ch Transmitter (Cirrus/Futaba Compatible) tp my PC to use with FMS Model Simulator. Originally did not have a Trainer Port but a friend of mine added ont to my radio and his which was the same type. They worked well together as Trainee/Instructor. I am not sure if the signal levels are the same as that required for PC Interface. The PPM signal is present but the pulses are -0.5V in amplitude and they are sitting on a base voltage of -3V. Or 0.5v sitting on a base of 3V (if you reverse the polarity. Is this what it should be ? If not, what should the voltage levels be ?
Thanks for any help you can provide.

The USB-Interface works with a base voltage and signal difference of 3 V. It can also use both positive and negative modulation, so it should work with your transmitter.
