Appendix II : Proprietary NMEA input message SetSerialPort 1. 100 100—SetSerialPort This
command
message
is
used
to
set
the
protocol
(SiRF
binary
or
NMEA)
and/or
the
communication parameters (Baud,data bits, stop bits, and parity). Generally, this command is used to switch the module back to SiRF binary protocol mode where a more extensive command message set is available. When a valid message is received, the parameters are stored in battery-backed SRAM and the Evaluation Receiver restarts using the saved parameters. Table II-1-1 contains the input values for the following example: Switch to SiRF binary protocol at 9600,8,N,1 $PSRF100,0,9600,8,1,0*0C Table II-1-1 Set Serial Port Data Format
Note: SiRF protocol is only valid for 8 data bits, 1 stop bit, and no parity Page 17 of 22

NavigationInitialization 2. 101 101—NavigationInitialization This command is used to initialize the Evaluation Receiver by providing current position (in X, Y, Z coordinates), clock offset, and time. This enables the Evaluation Receiver to search for the correct satellite at
the
correct
signal
parameters.
Correct
initialization
parameters

SetDGPSPort 3. 102 102—SetDGPSPort This command is used to control the serial port used to receive RTCM differential corrections. Differential receivers may output corrections using different communication parameters. If a DGPS receiver is used that has different communication parameters, use this command to allow the receiver to correctly decode the data. When a valid message is received, the parameters are stored in battery-backed SRAM and the receiver restarts using the saved parameters. Table II-3-1 contains the input values for the following example: Set DGPS Port to be 9600,8,N,1. $PSRF102,9600,8,1,0*12 Table II-3-1 Set GPS Port Data Format:
Note: RTCM is not supported.
Query/Rate Control 4. 103 103—Query/Rate This command is used to control the output of standard NMEA messages GGA, GLL, GSA, GSV, RMC, and VTG. Using this command message, standard NMEA messages 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. Table II-4-1 contains the input values for the following example: 1. Query the GGA message with checksum enabled $PSRF103,00,01,00,01*25 2. Enable VTG message for a 1 Hz constant output with checksum enabled $PSRF103,05,00,01,01*20 3.
