Hi, I must connect a smart meter “Chint DDSU666-D 80A 1Ph” to a CERBO Gx.
From smart meter come out 2 wires using RS485 protocol.
According the meter manual, I must connect this 2 wire to the pin 7 and 8 on the RJ45 connector.
I read the Cerbo Gx manual and in the wiring picture seems I must use the USB port, not the RJ45 port, but in the picture use Zigbee wireless to RS485 adapter and Zigbee wireless to USB, not direct by wire. it’s that true? What connector I must use?
What pins I must connect to the 2 wires?
Thanks.
