Troubleshooting Guide 

 

Trouble Locking onto Satellites 

If the VBOX 3i is having trouble locking onto satellites then please follow the checklist below for typical solutions: 
 

 

Ensure that the antenna is placed in a position where it has an unobstructed vi

ew of the sky. (See „GPS Antenna Placement‟ below) 

 

Check the antenna connection with the VBOX 3i; only small amounts of dirt in the socket can cause a significant reduction in signal strength. Also check the 
cable at the plug and along its length for any damage. 

 

Check that the power supply is connected and free from damage. 

 

If possible try another known working antenna, to confirm antenna functionality. 

 

Perform a GPS Coldstart and then leave the unit powered up in an open static position for at least 15 min

utes. See „VBOX 3i not responding‟ below. 

 
Once the VBOX 3i has locked on to 4 or more satellites it will be ready for use. 
 

No Communication with PC 

 

If the red LED on the front of the VBOX 3i is not illuminated then there is no power to the unit; check that battery contains adequate charge or, if using a 
cigar lighter, check internal cigar lighter fuse. 

 

Check that the correct COM port has been selected in VBOXTools 

 

Check that no other programs are using the same COM port. 

 

Disconnect the power to the VBOX 3i then reconnect it. 

 

COM Port Unavailable 

 

The computer may have been started with a different VBOX 3i connected to it; disconnect the VBOX 3i, restart the computer then reconnect the VBOX 3i. 

 

Another software package installed on your computer may have reserved the COM port. 

 

No Data is logged to the VBO file 

 

Check satellite reception. Loss of reception may prevent data from being logged to the card (dependent on logging mode).
