Commands
To upload ephemeris and almanac data, perform the following steps:
1. Use the $PASHQ,SNV and $PASHQ,SAL commands to obtain ephemeris
“SNV” and almanac “SAL” data from another running Ashtech receiver. Save
the generated SNV and SAL messages in a file.
2. Issue the $PASHS,PRR,Y command to the receiver to be uploaded.
3. Use a file upload utility such as gterm.exe or term90.exe in Norton
Commander to upload the previously logged SNV and SAL files.
4. The $PASHR,ACK response generated by the receiver after each
successfully decoded ephemeris or almanac record.
PRT: Serial Port Baud Rate
$PASHQ,PRT,[c1]
This command allows you to query the baud rate code of the G12 serial port to
which you are currently connected, where [c1] is the optional serial port designator
for the output of the response. If a port is not specified, the receiver sends the
response to the current port. Issue the query command $PASHQ,PAR to see the
baud rate codes for both serial ports.
$PASHR,PRT
The response is output in the format:
$PASHR,PRT,c1,d2*hh
Table 4.32 defines the parameters.
Table 4.33 lists baud rate codes and the corresponding baud rates:
