C). Set DGPS Port ID:102 Set PORT B parameters for DGPS input
This command is used to control Serial Port B that is an input only serial port
used to receive
RTCM differential corrections.
Differential receivers may output corrections using different
communication parameters. The default
communication parameters for PORT B are 9600
Baud, 8data bits, 0 stop bits, and no parity. If a DGPS
receiver is used which has different communication parameters, use this command to allow
the receiver to correctly decode the data. When a valid message is received, the
parameters will be stored in battery backed SRAM and then the receiver will restart using
the saved parameters.
