Reading garbage from serial port, reborn

Re: reading garbage from serial port PiTInfo
I just got the pitinfo v1.2 throwing garbage at me.
I have tried different settings for serial port ( baud, parity, flow control), using picocom and https://hallard.me/enable-serial-port-on-raspberry-pi/
I have check cabling by connecting module directly to EDF appliance
Any idea (Ie proper serial port settings)
Thanks in advance

Thomas, there is a problem detected by Linky users, to be able to works a resistor need to be changed.
- R3 (4.7K) need to be changed by 1K, 1.2K or 1.5K (and may be 2.2K) whatever you have in hand.
- or put another resistor from 800 Ohm to 1.8K in // of R3 leaving R3 in place.
If you can't do it, you can send me back the board and I'll do it for you.

Bonne journée à tous.
Une autre victime de Linky ici.
Avant de changer R3, je ferai un différentiel adaptateur pour mon oscilloscope.
Mon installation a une connexion parallèle de la téléinfo bus.
Je pense qu'un «récepteur de ligne» à haute impédance est nécessaire?sorry for the baby french, I'm a slow learner.

Bonjour Charles,
je viens d'installer et configurer la PiTinfo sur mon Raspberry et je rencontre le même problème.
Lorsque je lance picocom, le début de trame est lisible puis je n'ai que du déchet.
Mes compétences de soudage sont très limitées et les composants tout petits...
Etes-vous toujours ok pour remplacer la R3 si je vous renvoie la carte?
Merci
