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

@ThomasC
What version of PI and EdF counter do you have RPI 3, Linky, ... ?
-
@Charles It's a RPI 3 and a linky.
-
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.

@Charles Thanks for the feedback. I am out of office ATM. I'll see what i can do at end of week. But my soldering skills are poor.

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.

Oui tu peux changer juste R3 et voir si tout fonctionne, après. Sait-on jamais ;-)

je pourrais faire ça.Mais je préfère voir ce qui se passe en premier....Strebor
