Connect Smart Meter to Cerbo GX

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.

@kyuketsuki

This smart meter is not supported and will most likely not work with a GX device. Best ask the manufacturer of the smart meter. And you may also take into account that this could void warranty in case something goes wrong.
