Identifying your R/C Transmitter and the trainer socket:

The socket usually resides at the rear of the R/C Transmitter. Do not confuse it with the charger (DC) socket.
Find the socket with the eight small holes inside a round area with a notch:

What you will need:

1. Eight-pin DIN plug that fits into the trainer socket. Five-pin DIN (180° type) and Seven-pin DIN plugs will also fit.
   
2. One 3.5mm audio (mono) jack that fits into the your soundcard’s audio input (e.g. Microphone). As in the following figure
3. About 2 meters of cable by which you will connect your R/C Transmitter to the sound cardsound card. The cable should consist of 2 or more electrical wires. It is preferable that the wires will be coated with insulators of different colours so you can distinguish between the two.
4. Soldering equipment.

Soldering:

• Use the connection diagram to guide you in your work.
• The plug is viewed from behind the plug, the way you see it while soldering.
• The signal line (red) connects pin 4 to the central tab of the audio jack.
• The ground line (black) connects pin 3 to the external tab of the audio jack.
• Connect pin 3 to pin 5.
