MoTeC Introduction Introduction This manual covers the operation of the MoTeC Lap Beacon. -
Page 4: Overview
Logging system or to an Engine Management System. The Lap Beacon system is used to mark the start of a Lap. This can be used by a display system to show the driver lap times and lap number and can be used by a data logging system for lap time and start of lap information. -

20 to 25m Maximum Range The MoTeC Lap Beacon has a range of up to 25m (80ft). The range depends on the alignment of the transmitter and receiver. For operation up to 25m (80ft) both the transmitter and receiver must be aligned within 2°... -
Page 6: Lap Beacon Use
Lap Beacon Use Normally the MoTeC Lap Beacon is used as a standard Lap beacon, ie. one beacon transmitter placed at the start of the lap. The beacon ID should be set as recommended above to ensure that no two teams use the same number. -
Page 7: Verifying Operation
Verifying Operation To test if the lap beacon is working correctly, aim the transmitter at the receiver, the Red LED on the receiver should glow brightly. If the LED glows very dimly then the receiver and transmitter numbers probably do not match. -
Page 9: Beacon Transmitter
If the same position cannot be used then the MoTeC Interpreter software can compensate for the offset in the beacon position. -
Page 10: Id Number Adjustment
Beacon Transmitter • For operation up to 20m (65ft) the beam must within 5° of parallel to the road surface. Beam Pattern The approximate beam pattern is shown below. The pattern shows the limits of operation, when the beacon receiver is within 2°... -
Page 11: Power
MoTeC Beacon Transmitter • The beacon transmitter will operate when the LED is orange, however the transmitted power is reduced which reduces the operating range. Power The unit should be powered from a 12V rechargeable battery. A small car battery is recommended as it is easily charged and will operate the transmitter continuously for up to 20 days. -
Page 13: Beacon Receiver
MoTeC Beacon Receiver Beacon Receiver Mounting Mount using the plastic mounting plate attached to the base of the beacon receiver. Do not earth the Case. The receiver mounting should be designed to allow the receiver to be mounted at either side of the vehicle, depending on which side of the track the transmitter will be located. -
Page 14: Led
Beacon Receiver zero, this special case allows the receiver to report all beacons with the same Mode setting for split beacon use. The output of the beacon receiver is encoded with the beacon number to allow the beacon transmitter number to be identified, this is normally only required for split beacon use so that the Lap Beacon may be identified. -
Page 15: Wiring
Wiring The beacon receiver signal wire should be connected to a Digital Input on a MoTeC ADL Dash/Logger or MoTeC ECU Do not run the wiring near the engine ignition system. The receiver must be powered by 8V from an ADL or ECU. The receiver may be damaged if connected directly to battery voltage. -

Page 17: Trouble Shooting
• If the battery voltage is less than 10.5 Volts charge the battery. • If the battery voltage is greater than 10.5 Volts, return the unit to MoTeC for servicing. LED Off Check that the battery is connected correctly, Red to Positive, Black to Negative and that the battery is supplying at least 10.5 volts. -
Page 18: Check List: Operational Problems
Trouble Shooting the switches are set correctly, particularly on the Receiver where the switch identifications are marked under the Lid. LED Off Check that the receiver has 8 volts between the red and black wires. Note that the connected device (ECU or ADL) must have its power turned on. - Page 19 MoTeC Trouble Shooting • Check that the Receiver is not aimed through glass, as this can significantly reduce the range. • Check that the Transmitter and Receiver are aligned correctly, both must be within 2° for 25m operation or 5° for 20m operation.
