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 |
