At a 2-Hz output rate, a baud rate of 115,000 bps is required to output all the raw data (MBN, PBN,
SNV, SNG, SAL, and SAG) and NMEA messages. At higher output rates, the raw data must be split
between two serial ports, or some of the messages should be turned off. To receive data at high baud
rates (e.g., 115,000), you must ensure that your computer has a suitable serial I/O capability. Most
computers with 486 or Pentium processors and 16550 UART serial ports can support high data
rates. For a 5-Hz update rate, the $PASHS,POP,5 command should have been sent previously.
Example: Set recording interval to 5 seconds
$PASHS,RCI,5<Enter>
REC: Turn Data Recording On/Off
$PASHS,REC,c
Turn data recording on or off, where c is Y (yes) or N (no). The Default is Y.
RID:Receiver ID
$PASHQ,RID,c
This query command allows you to display the receiver ID, firmware version, and
installed options, where c is the optional output port.
Example: Query the receiver in to the current port.
$PASHQ,RID<Enter>
$PASHR,RID
The response to the $PASHQ,RID command is a message in the form:
$PASHR,RID,G2,s1,s2*cc
where:
G2 = GG Surveyor
s1 = firmware version
s2 = installed option
For more information on the options, see “Receiver Options” command on page 4.
