Frequently Asked Questions
Alarms
Why does my Meridian not make an audible beep when I have an alarm 
active? 
Check your setup settings for the Beeper. If the selection is Off 
or Keys Only, the beeper will not sound for alarms. 
Output Data
What is NMEA?
NMEA (National Marine Electronics Association) is the 
standard used for interfacing marine electronic devices. This 
standard has also been adapted for use in a variety of third-party 
mapping software programs. 
What are the NMEA message strings?
The Meridian supports version 1.5 and 2.1 of the NMEA 0183 
standard. 
Additional information on NMEA can be found at on the 
internet at www.nmea.org, where you can purchase the NMEA 
Interface Standards. Another excellent source for NMEA 
standards is a FAQ sheet that is published on the internet by 
Peter Bennett at vancouver-webpages.com/peter/nmeafaq.txt. 
My GPS is not communicating with my computer. What can I do?
Check your baud rate and check the baud rate that your software 
is using. If they don’t match, change either the software’s or the 
Meridian’s baud rate (See Setup - Changing the Baud Rate.) 
Can I interface my Meridian with a Macintosh computer?
Magellan does not supply cabling or software for the Macintosh 
line of computers. For information on a cable or software that 
may meet your requirements, visit GPSy at www.gpsy.com on 
the internet.
