GNSS
►GPS+SBAS+DGPS – only GGA data with a
QI value of "2" or higher is accepted (3, 4 or 5 are also
accepted).
NOTE: All console based mapping, application and
guidance functions are ceased if the GGA QI value drops
below "2" with this setting checked.

Exit this screen to begin initializing the GNSS receiver. This
takes about a minute, and the console will not respond until
complete.

GNSS port
The COM port can be set to “Internal” to use the internal GNSS
receiver and transmit out, or “External” to receive external GNSS
data.
1.
Press DOWN arrow
to access the list of options.
2. Select:
►Internal – uses position data from the internal GNSS
receiver; these NMEA data are sent out the RS-232 serial
"Port A" of the Matrix harness at 115,200 baud
►External – uses position data from an externally attached
GNSS receiver attached to the RS-232 serial "Port A" of the
Matrix harness
NOTE: An external receiver is required to work with TerraStar,
OmniStar HP/XP, or RTK position data.
