Chapter 6 Troubleshooting
Case 1
No output
Suggested Solution:
Check whether the Com Port is enabled and whether you are using correct power
supply.
Case 2
GPS Data is not in correct order
Suggested Solution:
During the FIRST COLD START, when GM-44-FB is turned on at your location, the
unit automatically searches for satellites and accumulate new data for your receiver and
this may take four to five minutes.
Note:
You can use any comm-program or WINDOWS TERMINAL to see the raw
data at 1 Hz, 4800 bps.
Case 3
No activity or the Map Software is not receiving any GPS data.
Suggested Solution:
In our FREE GPS program the software automatically searches for Com 1 and Com 2 data as
soon as the program is executed. Make sure that the
GM-44-FB
is connected to Com 1 and
Com 2.
