VB3i MANUAL

Page | 7 22 May 2014

Quickstart guide

Required equipment (All supplied as standard unless specified)

 VBOX3i

 RS232 cable

 Cigar lighter 12v adapter lead

 VBOX software CD

 GPS antenna

 Laptop PC (not supplied)

 Blank compact flash card

1. Mount the VBOX3i GPS antenna in a suitable position on the roof of the vehicle. The ideal position is

in the centre of the roof away from any objects that may shadow the GPS signal such as roof bars. This

creates a large metal object underneath the antenna to shield it from signals reflected by the ground

that can cause multi-path errors.

NB: See troubleshooting section if having difficulty obtaining satellite lock.

2. Screw the gold SMA connector on the antenna cable firmly onto the VBOX3i 'GPS' socket, making sure that the socket on the

VBOX3i is free from any contamination.

NB: It is important to connect the antenna to the VBOX3i before power is connected. The VBOX3i adjusts the signal gain to the

antenna based on the current incoming GPS signal strength.

3. Connect the power connector to the socket marked ‘PWR’ on the VBOX3i. .

When power is connected, the red ‘PWR’ LED will illuminate and all of the other LEDS will flash once then go off.

4. Allow the VBOX3i time to acquire satellite lock (This should take no longer than a few minutes.) before moving off to log data.

It is good practice to do this at the beginning of your day; after you have done this satellites will be instantly picked up and

locked onto, even after periods of the power being switched off or overhead obstructions blocking the view of the sky.

If the VBOX3i has not been used for a long time or if it was last used many miles from its current location, it may take time to

find satellite lock. If this situation arises perform a GPS coldstart to reset the GPS engine.

NB: See troubleshooting section for more info on carrying out a GPS coldstart.

5. The ‘GPS’ LED will be lit solid red when no satellite lock has been obtained, once the VBOX3i gets a lock on visible satellites,

the ‘GPS’ LED will flash green to indicate the number satellites. At a normal test track facility you should expect to see between 7

and 12 satellites being received by the VBOX3i. When the VBOX3i has a lock on 4 or more satellites then the VBOX3i is ready to

use.

NB: If fewer than 7 satellites are consistently seen the position of the GPS antenna on the vehicle may not be ideal, or the

nature of the test surroundings may not be ideal; see troubleshooting section on antenna positioning.

6. Now simply drive the vehicle. In the VBOX3i’s default mode it will log all data when the vehicle is moving at a speed above 0.5

Kmh and stop recording when the vehicle’s speed goes below 0.5 kmh.

The blue CF LED on the front panel of the VBOX3i will flash to indicate when data is being logged to the CF card.

7. When you have finished your first test with the VBOX3i come to a halt, wait until the blue CF LED stops flashing before

removing the CF card. Logging can be stopped at any time by pressing the ‘LOG’ button to close the current file.

NB: If the IMU integration feature of the VBOX3i is to be used refer to the ‘IMU Integration’ section later in this manual.
