EDIT - Sorted itself out....not sure how.
I am definitely a beginner here.
I have a KH9.9 and have wired up a Waveshare Modbus adapter using POE.
I have the Modbus connected to a POE switch which is then connected to my Eero router.
When connected using POE, the power light on the WS is bright red. If I disconnect the ethernet cable and power the WS with a usb cable connected to a power socket, the power light is less bright.
With POE connected, I get a very faint yellow light on LINK. THe device is visible on Vircom.
My issue seems to be arising when I try to update the BIN file. I get a "flash wirte" error.
Any thoughts?
I've checked the wiring and pins and all seems fine.
I don't have the PoE version myself but I know a lot of people that use it sucessfully.
The Waveshare has a wide voltage tolerance but when connected via USB it is at it's lowest range (it can be as low as 3.3V but more typically ~5V), whereas PoE is closer to 48V and so I would definitely leave it connected this way.
If it's showing in Vircom that is a good start, I know a few users have had to do factory resets when trying to flash firmware, from memory you have to add a link across a couple of pins to do that.
From my own experience of using the non PoE version, I found that the ethernet port isn't particularly fast (10-100Mb) and so I set it to a fixed speed rather than auto in the switch.
