Command
Check Sequence Number
$PASHS,RTC,SEQ
Checks sequence number of received messages7 and, if sequential, accept
corrections; if not, don't use correction. The command structure is
$PASHS,RTC,SEQ,x where x is Y (check) or N (do not check). Default is N. Used
only in REMOTE mode. Valid only at beginning of differential operation. After two
sequential RTCM corrections have been received, differential operation begins.
Example: Check sequence number
$PASHS,RTC,SEQ,Y
Set RTCM Bit Rate
$PASHS,RTC,SPD
This command sets the number of bits per second that are being sent to the serial port
of the base station. The command structure is $PASHS,RTC,SPD,x where x is the
code for the output rate in bits per second. The available speeds are 25, 50, 100, 110,
150, 200, 250, 300, and 1500 as listed in Table 4.76. . Default is 300 bits per second.
Used only in BASE mode.
Example: Set bit rate to 110 bits/sec
$PASHS,RTC,SPD,3
If burst mode is selected, the message is sent at the configured serial port rate.
Set Station Identification
$PASHS,RTC,STI
This command sets the user station identification (user STID) to any value between
0000 and 1023. The command structure is $PASHS,RTC,STI,xxxx where xxxx is
the station identification. In RTCM differential mode, corrections will not be applied
if the station ID of the base and rover are different, unless the rover is set to zero. If
the user STID of the rover station is set to zero, the sensor will attempt to use the
differential corrections it receives, regardless of STID of base station. Default is
0000.
Example: Set site identification to 0001
$PASHS,RTC,STI,0001
