MoTeC Beacon Transmitter 9
BTX 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 holes may be used to mount the unit to a backing plate. Note that the
backing plate should include a hole so that the power LED is visible.
Note that any mounting system must ensure that the case remains watertight.
The transmitter should not be mounted in an enclosed case as very high
temperatures can cause a reduction in transmission power.
