CSI turns off all output except the GPGGA sentence. The time required to output a NMEA sentence can be determined by multiplying the maximum number of characters by 10 then dividing the result by the baud rate. Selected sentences will be transmitted at a periodic rate based on the selected baud rate and the selected output sentences. The sentences will be output contiguously. Regardless of the baud rate, the sentences are reference to the PPS signal immediately preceding the GPRMC sentence, or whichever sentence is output first.

In Table D-3 default Output indicates NMEA sentences that are Garmin16-
HVS defaults. CSI turns off all output except the GPGGA sentence. The time
required to output a NMEA sentence can be determined by multiplying the
maximum number of characters by 10 then dividing the result by the baud rate.
Selected sentences will be transmitted at a periodic rate based on the selected
baud rate and the selected output sentences. The sentences will be output
contiguously. Regardless of the baud rate, the sentences are reference to the
PPS signal immediately preceding the GPRMC sentence, or whichever
sentence is output first.
