VBOX 3 not responding - GPS Coldstart
The GPS engine has locked up.
Perform a GPS Engine Coldstart
A GPS coldstart forces the GPS engine to reset its downloaded almanac of current satellite positions. This can be useful if the VBOX 3 is having trouble
locking onto satellites, which typically occurs if the VBOX 3 has not been used for several weeks or if it was last used a long distance (over one thousand
miles) away from the current location.
After performing a GPS coldstart leave the VBOX 3
powered up in a static location where the antenna has an unobstructed view of the skies until the „GPS‟
LED becomes solid green.
Once the VBOX 3 has downloaded the new almanac it will reacquire satellites in noisy situations (such as near trees, buildings and under bridges) much
more quickly. It will also acquire satellite much more quickly on power-up.
To perform a GPS coldstart on the VBOX 3 perform the following actions:
Press and hold the „LOG‟ button on the front of the VBOX 3 for five seconds until a long beep is sounded.
When the button is released the „GPS‟ LED will start to flash red showing that the Coldstart has been performed and the GPS engine is now not
locked onto any satellites.
After approximately 30-
45 secs the „GPS‟ LED will start to flash green indicating that satellite lock has been achieved and indicating the number of
satellites that it is locked onto.
Firmware Upgrades
Firmware refers to the operating software inside the VBOX III. The firmware is responsible for all of the functions within the VBOX and from time to time,
firmware updates will be released by Racelogic to improve or enhance the way that the VBOX works. The latest firmware will always be available on the
Racelogic web site in the downloads directory:-
http://www.racelogic.co.uk/2003/vbox/downloads.htm
It is recommended to check the web site p
eriodically for updates. The VBOX III upgrade files have a “.UPG” file extension. To upgrade the VBOX III firmware,
download the latest firmware file from the Racelogic web site and copy this file onto a compact flash card. Then insert the compact flash card into the VBOX
III. Apply power to the VBOX. All three LEDs on the front panel should illuminate. After a short period of time, the green and blue LEDs on the front panel will
flash. When the LEDs stop flashing the VBOX will re-initialise and begin normal operation. This will be indicated by the green SAT LED flashing slowly as the
VBOX searches for satellites.
After upgrade, the UPG file will be deleted from the flash card and an upgrade log file will have been created. This log file can be emailed to the support
address below should any problems arise.
If you have any questions regarding upgrade of VBOX, please do not hesitate to contact
