What settings are required for OpenRTK330L? Does it mean that the settings on the OpenRTK330L side are unnecessary just by registering the server in the software on the Ntrip Caster side?

I would like to use OpenRTK330L as Ntrip's Server.Is it possible? I'm thinking of SNIP (https://www.use-snip.com) for Caster. It is best to connect with SerialStream (Dsub9:RS232), but if it is impossible, Ethernet connection is also acceptable. What should I set for OpenRTK330L in the browser?No suitable material found. is there a description somewhere?

Can OpenRTK330 be set as a base station for SINP?
I want to use it as StreamSerial for RS232 connection. If it can't do that, I can use an Ethernet connection as the next best option.
Please also tell me the setting contents when setting as Base in Browser.

I couldn't find it in the manual below.
