Appendix A. Changing GPS16X-HVS Settings

A-4

In Table A-4 default Output indicates NMEA sentences that are GPS16X-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.
