$PASHQ,PHE,[c1]
This command queries the current photogrammetry edge setting, 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.
$PASHR,PHE
The response message is output in the format:
$PASHR,PHE,c1*hh
Table 6.33 outlines the parameters.
Typical PHE response message:
$PASHR,PHE,R*57
Table 6.34 outlines the response message.
PMD: Position Mode
$PASHS,PMD,d1
