Introduction
The VBOX 3i represents the 3rd generation of GPS data logging system from Racelogic. Using a powerful new GPS engine, the VBOX 3i can log GPS and other
data at 100Hz. The logged data is stored directly onto a compact flash card for easy transfer to a PC.
The VBOX 3i also includes 4 high-resolution analogue input channels to record data from external sensors and 2 CAN bus interfaces to allow connection of
Racelogic input modules while simultaneously transmitting GPS data on the second bus.
In line with previous VBOX models, the VBOX 3i is compatible with all of the existing peripherals including the Multifunction display, ADC03, TC8, FIM03 and Yaw
rate sensor. To use the IMU integration feature of the VBOX 3i an IMU02 is required.

Troubleshooting Guide

VBOX 3i 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 3i is having trouble locking
onto satellites, which typically occurs if the VBOX 3i 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 3i 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 3i 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 3i perform the following actions:
• Press and hold the ‘LOG’ button on the front of the VBOX 3i 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.
