Hi,
We tested the wiring that I provided to you and it's working, could you please check these things?
- If your RS485 is enabled in WebUI, because it's disabled by default.
- Check your RS422 device configuration, RUT955 RS422/485 port can only work in 8 data bits and 1 stop bit. So make sure it's all set-up accordingly from both sides.
