Select the Correction format you wish to use from the box and then select the baud rate
from the Serial port settings (radio modem). The most common baud rates used for
differential corrections are 4800 baud and 9600 baud. The RT-Base S and GPS-Base use
9600 baud. The values in the Data bits, Parity and Stop bit fields should be set to match the
incoming signal.

When selected, the “Enable NTRIP corrections” checkbox box configures the RT for

configure the settings of the NTRIP client inside the RT.
