GPS Setup and Function

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.

Test the Garmin16-HVS for proper operation including the baud rate and

output string. Use a computer, terminal emulator software, a serial port

(RS232), and a 9-pin to 9-pin serial cable. The computer and serial port can be

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

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

works. Procomm ™ is another communication software package that works

well.
