SPD: Baud Rate for RTCM Message Output
$PASHS,RTC,SPD,d1
This command sets the base station’s output rate for RTCM messages in bits per
second (bps), where d1 is a code number between 0 and 8. Table 9.5 lists the
available bit rates and corresponding codes. The default output bit rate is 300 bps.
This command applies to base station mode only. You can view the current output
bit rate setting by entering the $PASHQ,RTC command and checking the SPD field.
Example
Enter the following command to set the output bit rate for RTCM messages to 1500
bits per second:
$PASHS,RTC,SPD,8
