“Used this cable to connect my Raspberry Pi4 to my Victron equipment in my Motorhome, works a treat and I can now monitor my batteries and solor from anywhere in the world.”
“I haven't used it yet. Part of the reason for this is that there were no instructions supplied. There are 4 pin connectors supplied. For RS485 I only need 2 pins (plus maybe an earth). Which two should I use, and which way round?”
