XDR: Transducer Measurements
$PASHS,NME,XDR,c,s
Enable/disable the transducer measurements message, where c is the output port, and
s is ON or OFF.
This message simply transfers the XDR message received from external transducers
(through $WIXDR and $YXXDR NMEA message or Ashtech format
$PASHS,XDR) for use by the control station, so that the control station can have
access to all measurements, GPS data and transducer data through a single
communication link.
Example: Enable XDR message on port A
$PASHS,NME,XDR,A,ON <enter>
$PASHQ,XDR,c
Query Transducer measurements, where c is the optional output port and is not
required to direct the response to the current port.
Example: Send query of XDR message on port A
$PASHQ,XDR,A <enter>
$GPXDR
As indicated above, the format of the response is the same as the format of the input
from the transducer ($WIXDR and $YXXDR). The messages are in the form:
$GPXDR,c1,f2,c3,s4, c5,f6,c7,s8,..., c n,f n+1,c n+2,s n+3*cc <enter>
Each data from the transducers have the form c1,f2,c3,s4 and several transducer data
can be sent in the same message as long as the entire string is not longer than 180
characters.
