Quick Start - Speed Sensor Dual Antenna

For Slip and Pitch measurements

Required equipment (All supplied as standard unless specified):

• VBSS100SL

• Connecting Loom (RLCAB093-C)

• VBOX File Manager + RLCAB005-C

• 2 x GPS & GLONASS antenna (RLACS156)

• Tape measure

1. The Speed Sensor unit needs to be mounted flat inside the test vehicle. Failing to do so will have an impact on the

accuracy of the calculated slip channels.

2. Mount the GPS/GLONASS antennas on the vehicle roof in-line with the direction of motion, and clear from any

obstructions (see image below). For normal operation, place the primary antenna (Socket A) at the rear of the car,

and the secondary antenna (Socket B) at the front. All measurements are made from the primary antenna.

3. Make sure the antennas are rotated so the wires exit in the same direction as each other.

4. Accurately measure separation distance to the nearest 5 millimetres, for best accuracy measure from the point at

which the cable exits the antenna.

5. Power up VBSS100SL.

6. Connect VBOX Manager to VBSS100SL via Lemo CAN connector on RLCAB093-C.

7. Through VBOX Manager, go into VBOX->DUAL ANTENNA->SEPARATION and enter the separation of the

antennas.

Page 2 Speed Sensor has not used for a long time, or the location where it is being tested has changed drastically, a GPS coldstart may be required. Note that Racelogic Config software must be used to do this. For Slip and Roll measurements Follow the same steps as ‘Slip &...
Page 3 Translating this position back to the centre of the car will make the slip measurement consistent when turning both ways. Antenna Placement Whilst installation and use of the VBSS100SL is intended to be fast and simple, careful attention must be paid to placement of the antennas.
