Appendix A. Changing GPS16X-HVS
Settings
As configured by Campbell Scientific, the GPS16X-HVS will output the
NMEA 0183 $GPGGA and $GPRMC data strings once a second, the PPS
signal is enabled with a duration of 100 milliseconds and the baud rate is set to
38,400 baud.
Special software (SNRSRCFG.EXE) is available from Garmin International
for system setup. The GPS16X-HVS user manual available from Garmin
International provides technical details beyond the scope of the Campbell
Scientific user manual.
Settings used by Campbell Scientific for GPS16X-HVS setup:
GPS Base Model = GPS 16(X)
Fix Mode = Automatic
Baud Rate = 38,400
Dead Reckon Time = 30 sec
NMEA output time = 1 sec
Position pinning = off
NMEA 2.30 mode = off
Power Save Mode = off (Normal mode)
PPS mode = 1 Hz
PPS Length = 100 mS
Phaze output Data = off
DGPS Mode = WAAS only
Differential mode = Automatic
Earth Datum Index = WGS 84
Selected Sentences = GPGGA and GPRMC
Common changes would be baud rate and selected sentences. The NMEA 0183
GPVTG data sentence gives ground speed and direction, which may be
required for some applications. Changes can be made with the Garmin
software, or with a terminal emulator and the Garmin technical user manual.

A.1 Computer Connections
Either an A200 interface or a DB9-Female-to-Terminal-Block interface is
required to connect the GPS16X-HVS to a computer. The A200 is used to
connect to a computer USB port, and the DB9 Female to Terminal Block is
used to connect to a computer 9-pin serial port.
A.1.1 Using the A200
A.1.1.1 Driver Installation
If the A200 has not been previously plugged into your computer, the A200
driver needs to be loaded onto your computer.
