Configuring the Data Message Output
The H220 features four primary bi-directional ports (Ports A, B C and D. You can configure
messages for all ports by sending proprietary commands to the H220 through any port. For a
complete list of commands and messages refer to the Hemisphere GNSS Technical Reference
Guide.
‘THIS’ Port and the ‘OTHER’ Port
Both Port A and Port B use the phrases “THIS” and “OTHER” when referring to themselves and
each other in NMEA messages.
‘THIS’ port is the port you are currently connected to for inputting commands. To output data
through the same port (‘THIS’ port) you do not need to specify 'THIS' port. For example, when
using Port A to request the GPGGA data message be output at 5 Hz on the same port (Port A),
issue the following command:
$JASC,GPGGA,5<CR><LF>
The ‘OTHER’ port is either Port A or Port B, whichever one you are not using to issue
commands. If you are using Port A to issue commands, then Port B is the ‘OTHER’ port, and
vice versa. To specify the ‘OTHER’ port for the data output you need to include 'OTHER' in the
command. For example, if you use Port A to request the GPGGA data message be output at 5
Hz on Port B, issue the following command:
$JASC,GPGGA,5,OTHER<CR><LF>
When using Port A or Port B to request message output on Port C, you must specifically
indicate (by name) you want the output on Port C. For example, if you use Port A to request the
GPGLL data message be output at 10 Hz on Port C, issue the following command:
$JASC,GPGLL,10,PORTC<CR><LF>
Saving the H220 Configuration
Each time you change the H220’s configuration you may want to save the configuration, so you
do not have to reconfigure the receiver each time you power it on.
To save the configuration, issue the $JSAVE command to the H220 using a terminal program or
Hemisphere GNSS’ applications (SLXMon or PocketMax4).
The H220 will save the configuration to non-volatile memory and indicates (after several
seconds) when the configuration has been saved. Refer to the Hemisphere GNSS Technical
Reference Guide.
