You should be configuring "PORT C" to either CMR or RTCM2.3. Either will work. I have used both in the past. Your first post stated you are connected to port C. I would turn RTKLNK off in port B. I also recommend using port C. The 252 has a history of auto-configuring port B and changing the settings on that port. Don't use port B for your RTK correction input.
