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.
Format:
PSRF102,<Baud>,<DataBits>,<StopBits>,<Parity>*CKSUM<CR><LF>
Example: Set DGPS Port to be 9600,8,N,1
PSRF102,9600,8,1.0*12
D). Query/Rate Control
output rate
This command is used to control the output of standard NMEA message GGA,
GLL, GSA, GSV
RMC, VTG. Using this command message, standard NMEA message may be
polled once, or setup for periodic output. Checksums may also be enabled
or disabled depending on the needs of the receiving program. NMEA
message settings are saved in battery backed memory for each entry when the
message is accepted.
