Example: Enable PTT message on port A
$PASHS,NME,PTT,A,ON <enter>
$PASHQ,PTT,c
Query the time tag of the next PPS pulse, where c is the optional output port. If c is
not specified, the reply is sent to the port on which the query was made.
The response will be sent out once, right after the next PPS pulse is generated, and
contains the GPS time at which the PPS pulse was sent, including the offset if an
offset was set when the PPS pulse was enabled. Thus the response may be delayed
by one PPS period plus the time tag latency indicated above.
$PASHR,PTT
The response message is in the form:
$PASHR,PTT,d1,m2*cc <enter>
Typical Response:
$PASHR,PTT,6,20:41:02.0000000*OD <enter>
RMC: Recommended Minimum GPS/Transit
$PASHS,NME,RMC,c,s
Enables/disables the Recommended Minimum specific GPS/Transit message, where c
is the serial port, and s is ON or OFF.
Example: Enable RMC message on port C
$PASHS,NME,RMC,C,ON <enter>
