Example
Enter the following command to set the baud rate of port A to 19200:
$PASHS,SPD,A,6
Enter the following command to set the baud rate of port B to 4800:
$PASHS,SPD,B,4
If you change the baud rate of the DG16’s serial port, be sure that the serial port of the device to
which the DG16 port is connected is set to the same baud rate.
STA: Satellite Tracking Status
$PASHQ,STA,[c1]
This command queries the current satellite tracking status, where c1 is the optional
port designator for the output of the response. If a port is not specified, the receiver
sends the response to the current port.
The response message has a free-form Ashtech format. Like the MEM and PAR
response messages, the STA response message does not have a header or
message identifier as shown in the following example:
TIME: 00:48:18 UTC
LOCKED: 31 25 29 23 21 15 08 03 01
COUNT: 42 46 47 37 45 48 40 36 49
Table 6.52 outlines the parameters.
SUI: Satellite Usage Indicator
$PASHS,SUI, x
This command enables or disables the satellite usage indicator, where x is ON or
OFF.
