I am not able to establish communication in system of:
Venus OS (Raspberry pi 3)
Multiplus II 48V/3000 (external wired Current Transformer sensor connected)
ET340 Carlo Gavazzi
MK3 VE Bus USB cable
VE Direct USB cable
I am able to communicate to ET340 via recommended USB-RS485 interface with PC to Carlo Gavazzi UCS7 original SW. But no response after plugged USB-RS485 interface to Raspberry pi. Just immediately after USB-RS485 plugged to Raspberry the LED (red and green) flashes approx. 1 second. Power meter ET340 is not visible in system (Setting-Energy meters).
I have tried a lot of variants (Address, Baud...) a lot of Reboot but no communication at all.
What is wrong? Do I need to setup anything?
