- Check all the NMEA data strings you want to include in
the output message and for those strings, choose an out-
put rate in seconds. Clear all the NMEA data strings you

GLL, GSA, GSV, RMC, RRE, VTG and ZDA.

ration window. MobileMapper CE is now set to output a
message via COM1 and virtual port COM2.

puting device via serial port (RS232), you must connect the
two devices using a null modem cable.
GPS Reset
Use the Reset GPS utility to cause the internal GPS receiver
to re-initialize. You may need to run this utility if for example
you want to force the GPS receiver to acquire new almanac
data from the GPS constellation and then use this data in the
position computation process.
, then Programs>GPS Utilities>GPS Reset. A warn-
- Tap on
ing message appears explaining that you are about to run
a cold reset (see screen opposite).
When you use this utility, in fact you clear the GPS
receiver's memory. That's why the time to first fix will be
longer after a cold reset than after a normal reset. Normal
reset takes place every time you turn on the unit.
- Tap on Cold Reset.
- After a few seconds, the message "Reset successful" is dis-
played. Tap OK to close the GPS Reset utility.
