C.) Set DGPS Port ID:102 Set PORT B parameters for DGPS input
This command is used to control Serial Port B, an input serial only port used to receive RTCM
differential corrections. Differential receivers may output corrections using different communication
parameters. The default communication parameters for PORT B are set for 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 decode data correctly. When a valid message is received, the
parameters are stored in a battery backed SRAM. Resulting, GPS receiver using the saved
Parameters for restart.
