Problem Reason 

Solution 

Test fail 

Poor connection 

Check the RS232 and PS2 connector or USB connector 
to make sure they are well connected. 

 Wrong 

BIOS 

setting for PS2 

 

Check the BIOS setting to make sure the PS2 port is 
enable. 

If you still get the testing fail message, contact your 
local distributor. 

 

Open com port 
fail 

All the serial COM 
port have been used 
for other 
application 
program 

Close all the other application programs and rerun the 
Sapphire Testing program. 

There is nothing 
showing on the 
tracking 
diagram even if 
the test result is 
success. 

Sapphire can not 
receive the GPS 
signal on the 
testing area. 

Move Sapphire to somewhere there is exposed to 
outdoors. 

 

Note: normally we cannot receive the GPS signal 
indoors. 

No position 
output but timer 
is counting 

 

1.Weak or no GPS 
signal can be 
received at the 
place Sapphire are. 

2.At outdoor space 
but GPS signal is 
block by buildings 

Go outdoor place without high building to block the 
signal and retest the Sapphire again. 

If operated 
Sapphire over 5 
minutes with 
nothing 
showing on the 
tracking 
diagram 

Maybe Sapphire 
received not 
enough data to sure 
tracking.   

Utilize the test program --- GPSDemo.exe to reset 
Sapphire. Please Click the icon
