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 M 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.
