    1512 You may use BNC to feed a serial connected device like a GNSS receiver. For that an incoming stream can be forwarded to a serial port. The following figure shows the screenshot of an example situation where BNC pulls a VRS stream from an NTRIP Broadcaster to feed a serial connected RTK rover.

     1512You may use BNC to feed a serial connected device like a GNSS receiver. For that an incoming stream can be forwarded to a serial port. Depending on the stream contents the receiver may use it for Differential GNSS, Precise Point Positioning or any other purpose supported by its firmware.

     1514<p>
     1515Note that receiving a VRS stream requires the receiver sending NMEA sentences (mode 'Manual' or 'Auto') to the Ntrip Broadcaster. The following figure shows the data flow when pulling a VRS stream or a none VRS stream.
