- 3.5 mm stereo jack male connector for the Interface,
- double-core cable e.g. microphone cable

The cable must be wired the way, that it fits the female connector of the Interface. The head of the 3.5 mm jack male plug is connected with GND, the contact in middle is connected with PPM signal.
The PPM signal can be modulated negatively or positively and its amplitude can range from 1 V to 12 V.
