Hardware

I used a RS485 adaptor sourced from Banggood, very similar to this

Mine is wired to the Sunsynk BMS 485 port (top left). I also have a RS485 port (bottom right) but this did not work.

The wiring and Ethernet color code according to TI-586A. The colours is probably not important, but it is important to use a twisted pair for RS485. Ideally always use either 586A/586B

RJ45 Pin	RS485 adaptor	Color (586A)
1	B/D-	Green-White
2	A/D+	Green
