From my experience a 252 should work on VRS.
For VRS one must first send an about location to caster. It can come from the 252 receiver autonomous position as NMEA or from the modem (could be a Lefebure NTRIP app internal android location). Caster software (CORS network) will then create a Virtual Reference Station near you and start streaming RTK corrections.
On 252 one should use the “port 3” for serial communications. This will be on B-blug. Other ports might be changed by “auto configure” no matter how you try and set them first by AgRemote.
Please refer to the252 user manual (easily found from net) for 252 pinout.
Serial settings naturally have to be right (baud rate etc..)
From my own experience I know that this might be hard to learn first but should be doable.
Just get it done in good time before getting to the actual shores on your fields. It is not plug and play...
