GPS16X-HVS GPS Receiver

6. Troubleshooting

Testing and evaluation of serial communications is best done by reducing the

whole system to small manageable systems. Usually some portions of the

whole system are working. The first steps involve finding what is working.

During this process you may find parts of the system that are not working or

mistakes that can be easily corrected. Fix each subsystem before testing

others.

6.1 GPS Setup and Function

Test the GPS16X-HVS for proper operation including the baud rate and output

string. Use a computer, terminal emulator software, a serial port (RS-232), and

a 9-pin to pigtail cable (SC110/sockets). The computer and serial port can be

the same as used to communicate with the datalogger. Terminal emulation

software is common. Hyperterm is supplied as part of Windows ™ and works.

Procomm ™ is another communication software package that works well.

Set up the software for the correct serial port, 38.4 kb baud, 8 data bits, 1 stop

bit and no parity. Flow control should be none. Using the SC110 cable,

connect the GPS16X-HVS to the computer serial port. Power up the GPS16X-

HVS. The GPS antenna should have a clear view of the sky. Don’t expect the

GPS antenna to work indoors. The $GPGGA and GPRMC strings should be

displayed once a second. Make sure the $GPGGA string is showing a valid

GPS fix. A valid GPS fix will display time, position and have a GPS quality

number greater than zero.
