Installing the transmitter at the
edge of the circuit
Fig. 87: Installing the transmitter
Information
If multiple vehicles with the Porsche lap trigger
system will be driving on a race circuit, only one
transmitter should be installed. The receiver cannot
differentiate the transmitters and detects each
passing of a transmitter as a new lap.
A commercially available camera tripod, for example,
can be used for adjusting the transmitter height.
Alternatively the transmitter can be placed on a flat,
firm surface.
NOTICE
Risk of damage to the transmitter.
The airflow from passing vehicles can cause the
transmitter to fall down or tip over.
e Choose the transmitter location so that a safe, firm
position is ensured.
1. Position transmitter A at the edge of the circuit at
the start line at the same level as the receiver in
the vehicle.
2. Align transmitterA parallel to the track.
Connecting the power supply for
the transmitter
Fig. 88: Power supply for the transmitter
A commercially available motorcycle or car battery,
for example, can be used for the power supply to the
transmitter.
e Make sure that the battery is sufficiently charged.
NOTICE
Risk of damage due to short circuit.
e Keep the battery dry.
e Make sure the polarity is correct.
1. Insert the red cable into the red connection on the
transmitter.
2. Insert the black cable into the black connection
on the transmitter.
3. Connect the red cable to the positive terminal (+)
of the battery.
4. Connect the black cable to the negative terminal
(-) of the battery.
Starting timing
