Ah, I did not know that. As soon as I saw the question in French my brain auto-translated it so I figured I would respond in kind.
Good to know!

Hello, sorry, I didn’t realize it needed to be translated into English.
I’ve read a lot, and you’re the best when it comes to Daikin. I tried connecting the Faikin to my air conditioner, but the connector isn’t the same as in the tutorials. My X50A connector (pictured) is different. However, I did manage to power it on the S21 port (2 power wires) with a working Wi-Fi connection. But there’s no status communication.
Could you please help me with my old port?
You can try the X50a port like mention in wiring of the Faikout project:
But seem your model too old, it may not work with green x50a, other solution is P1P2 port.
Why not just use the S21 port?
Hello and thank you for your reply. My S21 port only has two wires; it’s just for powering the Faikin. If I understand correctly.
Hello and thank you for your reply. Yes, I tried it on ports P1 and P2, but I must have fried it. Do you know how to connect it to P1 and P2? Will the remote still work?
I haven’t been able to find the wiring diagram for my X50A port; I’ve only found the white wire. Could you please help me?
Weird. First time I’ve ever heard of that. Normally the S21 is:
| Pin | Daikin Colour | Generic cable colour | Meaning |
|---|---|---|---|
| 1 | Brown | Orange | 5V - not always connected |
| 2 | Red | Blue | Tx from aircon - 5V logic |
| 3 | Orange | Yellow | Rx to aircon - 5V logic but most models accept 3.3V |
| 4 | Yellow | Red | 12V, or 14V, or some such - used to power Faikin |
| 5 | Blue | Black | GND |
Faikin or Faikout not support P1P2, only S21/S403/X50a. With X50A port on your main board you can try following.
X50 pin 3: TX
X50 pin 4: RX
You can try to swap TX RX if not working.
Power it by the X35A port, yellow color in the picture below will be 12V, Blue GND. From my image above it is far right near the green transformer.
If it does not work, I sell the P1P2 module, you can inbox me.
Okay, thank you. How much are you selling the P1/P2 module for?
