4.7 GBX-PRO Message Activation
The Ashtech G-12 high-accuracy, 12-channel GPS engine contained
within the GBX-PRO uses one command to set the various NMEA
messages output by the receiver. This command has the following
format:
$PASHS,NME,x,p,y<CR><LF>
The x field identifies the GPS message to be turned on or off, and may
be selected from {GGA, GLL, GSA, GSV, RMC, SAT, VTG, or ZDA}.
The p field indicates the data port to which the messages will be output,
where p = A for TXA (Pin-2), and p = B for TXB (Pin-6). The y field is
the activation status, where y = ON or y = OFF.
To change the update rate of the NMEA messages from the GBX-PRO,
use the following command:
$PASHS,NME,PER,p<CR><LF>
The p field specifies the number of seconds between successive
message outputs. The GBX-PRO is capable of outputting messages
at a maximum output rate of 5 times per second, or 5 Hz (p=0.2). An
optional software upgrade is available from CSI Wireless if 10 Hz
updates are required for your application.
Note - To operate with the 5 Hz position update, you must
reduce the message output to only the GGA message.
After receiver configuration, it is necessary to save all changes. The
following command will ensure that changes that you have made are
maintained after power is cycled:
$PASHS,SAV,Y<CR><LF>
