Beacon Transmitter 

Position 

The beacon transmitter may be placed at any point around the track.  

• 

It is recommended that the beacon transmitter is always placed in the 
same position at a particular track, this avoids offsets when data from a 
previous session needs to be compared with the current data. If the same 
position cannot be used then the 

MoTeC Interpreter

 software can 

compensate for the offset in the beacon position. 

• 

To ensure that the lap time recorded is the same as the official lap time, 
the beacon transmitter should be placed close to the official timing point – 
normally located at the start/finish line. 

Spacing between Transmitters 

The spacing between adjacent transmitters must be at least 6m (20ft) to avoid 
the signals from each transmitter conflicting with each other. This also 
includes other manufacturers’ beacons that emit an infrared beam. 

Mounting 

The beacon transmitter has 4 holes outside the sealing ring of the case, these 
may be used to mount the unit to a backing plate. Note that the backing plate 
should include a hole so that the LED is visible. 

Aiming / Range 

The Beacon Transmitter must be aimed so that the beam is parallel to the 
road and at the same height above the road as the vehicle receiver, therefore 
the mounting system must be capable of height and tilt adjustment. 

• 

For operation up to 25m (80ft) the beam must within 2

°

 of parallel to the 

road surface.
