Together with OcuSync Air System, Goggles RE can be used to transmit third-party radio control system stick signals from Goggles to S.BUS output of OcySync Air System. For this, a trainer port signal of a third-party remote controller is connected to the Goggles RE audio port that samples the pulse-width modulated signal chain. For debugging purposes, a visual display of the live state of 8 servo channels can be activated in Goggles RE.
The Goggles RE + OcuSync Air System user manual lists some supported third-party radio control system transmitters, such as models from Futaba, Frsky, Walkera, WFLY and RadioLink. Fine. For the purpose of wanting to use own (microcontroller based) trainer port signal generator, I am interested to know the maximum voltage level of the signal that can be injected into the audio port of Goggles RE (via mono 3.5mm plug)?
I assume, a 3.3V signal level is fine, but would like to know if 5V, or possibly even a higher signal level would also be OK.
Thank you!
P.S. The goal is to remote control a robot from far away by code running on a PC at base, where the control signal (e.g. servo positions) will be transmitted via the OcuSync link. The signal path would be PC -> custom signal converter -> Goggles RE -> OcuSync Air System -> S.Bus -> custom robot controller.
