the old forum has an interesting topic
anyone know how to connect a 6 wire usb to ttl cable DSD TECH SH-U06L Cavo da USB a TTL con chip PL2303GC (1,2 m/3,9 piedi) : Amazon.it: Informatica
to the pin header? which usb cable to which pin?
Ignore the green and red,
Brown to txd
Black to gnd
Yellow to rxd
Blue to vcc
if it doesn’t work swap brown and yellow.
Ok. Will try
try also my driver to integrate the charger into gui-v2
I have already added a USB <> VE.Direct interface to my IP22 and have Venus.OS running on a RPi but would not be sure where to start from the instructions on Github. ;-(
Unfortunately I don’t have my Victron system up at the moment so can’t really tell if I could manage to install your hack or not but feel I would probably need more advice re how / where to issue those commands?
Sometimes, if you know what you are doing it can be easy to forget those of us who don’t but who still could, with the right level of help. 
Cheers.
