Operation
4. For example, type in $PASHQ,PRT. If you have typed in and sent the
command correctly, you should get an immediate response on the display of
the external device
The response message typically might be:
$PASHR,PRT,A,5
This message indicates that the Sensor port A is using its default
communications setup 5 (9600 baud, eight data bits, no parity, and one stop
bit).
For a set command, which always begins with the header $PASHS, the
default acknowledge indication is hex 06 for a recognized command, and the
default not-acknowledge indication is hex 15 for an unrecognized command.
5. To change the response to a complete message, send $PASHS,CACK,0.
For information about the Sensor response, refer to “$PASHS,CACK” on
page 55.
Monitoring Satellite Tracking
For the following operations, the Sensor must be connected to a GPS antenna, and at
least four satellites must be tracked.
6. After connecting the Sensor to an antenna which has a clear view of the sky,
the Sensor should track satellites. When the Sensor is tracking satellites, the
LED on the front panel flashes green for each satellite. For example, if the
LED flashes green five times between red flashes, five satellites are being
tracked.
7. Type $PASHQ,STA and press <Ent er> or <CR><LF>. This command
queries which satellites are locked and their signal strength at the time the
command is sent.
The response message typically might be:
TIME: 20:09:36 UTC
LOCKED: 01 31 03 21 26 17 23 09 28
C/A S/N: 54 27 92 99 12 51 75 16 88
P1 S/N: 38 15 99 99 03 41 86 05 51
P2 S/N: 37 15 99 99 03 39 85 05 40
Monitoring Position
8. If interfacing through port A, type in capital letters:
$PASHS,OUT,A,NMEA
$PASHS,NME,PER,1.0
$PASHS,NME,GGA,A,ON
