4 USAGE INFORMATION
4.1 USING THE SMARTCARD-BOOSTER LEGIC
Place the Smartcard-Booster behind the windscreen of your vehicle as described in chapter 2.
The driver inserts his card and pushes the button on the Booster.
A beep should indicate that the card was successfully read.
The TRANSIT reader can identify your LEGIC card up to a distance of 10 meters now.
After 5 seconds the Booster returns into standby mode.
The driver should remove the LEGIC card from the Booster when leaving the vehicle.
4.2 READING THE SMARTCARD-BOOSTER LEGIC
The Smartcard-Booster is battery operated passive tag. The information from the tag is sent to the reader by a
method called modulated backscatter. This means that the reader's transmitted signal is modified in such way
that it can be recognized by the reader.
The examples below assume that a TRANSIT PS270 reader with P81 firmware is used and show the messages
transmitted on the RS-232 interface to a host system (TXD). Refer to the reader firmware manual for more details
about the reader communication protocol.
Dual-ID mode
The Smartcard-Booster cannot be identified until the driver inserts his card and pushes the button. Once the
button is pushed the booster reads the inserted card and sounds the buzzer upon a successful read. Both
vehicle-ID and driver-ID are transmitted to the reader. After 5 seconds the Smartcard-Booster automatically
deactivates.
Example: vehicle-id = 123, driver-id = 7100944, TXD = U00000001230007100944

If 'Extended Driver-ID length' is enabled, the following message is transmitted to the host.
Example: vehicle-id = 123, driver-id = 7100944, TXD = Y00000001230000000000000007100944

Single-ID mode
The Smartcard-Booster is 'sleeping' until the driver inserts his card and pushes the button. The LEGIC smart card
is read and the data is transmitted to the host system. After 5 seconds the Smartcard-Booster automatically
deactivates again.
Example: driver-id = 871111111117100944, TXD = U00871111111117100944

If 'Extended Driver-ID length' is enabled, the following message is transmitted to the host.
