Waveshare RS232/RS485 to Ethernet Converter Question

[preussal]

Hello,

I got a "Waveshare RS232/RS485 to Ethernet Converter".

I still have to see how I get the Seriel Port via the network on my Linux server.
Has anyone already had experience with it?
I could use it on my Mppsolar inverter via RS232 and make it independent of the computer.

I found nothing about it in the documentary.
Maybe someone can give me a few tips

Apparently you can do this with ser2net.
Or directly with Pyserial

protocols jk02, jk04 and jkv11 are for bluetooth connections and arent applicable to serial connections try jkserial, jk232 or jk485

[jblance]

if you are still interested, first update to version 0.16.22+ anf then try:
mppsolar -p /dev/ttyUSB0 -P jkserial -D
and post the results - this will allow me to diagnose
