Receiver Options
The GG Surveyor has a number of internal receiver options. The commands and
features you can use depend upon the options installed in the receiver. For example, if
the Photogrammetry option is not installed, you cannot use the $PASHS,TTT
command to output event time tags from the serial port.
Table 1.3 lists the available options. Each option is represented by a letter or number
presented in a certain order. You can verify the installed options by issuing the
$PASHQ,RID command to the receiver using an external handheld controller or PC,
as described in Chapter 6, Command/Response Formats.
The response displays the options as a 14 character alphanumeric string at the end of
the response message. For example:
$PASHR,RID,G2,GE00,55OPUBILEGMJCS
If the letter or number is displayed in the response message, the option is available. If
the letter/number is not displayed, the option is not available. Table 1.3 lists the
available options
