4 Usage information
4.1 Using the LEGIC Booster
Place the LEGIC Booster behind the windscreen of your vehicle as described in chapter 2.
The driver inserts his card and pushes the button on the LEGIC Booster.
A high beep indicates 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 (or authentication for LEGIC Booster Ultimate) the LEGIC Booster returns into standby mode.
The driver should remove the LEGIC card from the LEGIC Booster when leaving the vehicle.
4.2 Reading the LEGIC Booster
The LEGIC 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 by the LEGIC Booster in such
way that it can be recognized by the reader. For the LEGIC Booster Ultimate an active 433MHz transmitter is used for
secure authentication, this is done automatic.
The examples below assume that a TRANSIT reader with P81 firmware is used and show the messages transmitted on
the RS232 interface to a host system (TXD). Refer to the reader firmware manual for more details about the reader
communication protocol.
Dual-ID mode
The LEGIC Booster cannot be identified until the driver inserts his card and pushes the button. Once the button is
pushed the LEGIC Bbooster 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 (or authentication for LEGIC Booster Ultimate) the LEGIC
Booster automatically deactivates.
Example: vehicle-id = 123, driver-id = 7100944, TXD = U00000001230007100944 <CR><LF>
If 'Extended Driver-ID length' is enabled, the following message is transmitted to the host.
Example: vehicle-id = 123, driver-id = 7100944, TXD = Y00000001230000000000000007100944 <CR><LF>
Single-ID mode
The LEGIC 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 (or authentication for LEGIC Booster Ultimate) the
LEGIC Booster automatically deactivates again.
Example: driver-id = 871111111117100944, TXD = U00871111111117100944 <CR><LF>
If 'Extended Driver-ID length' is enabled, the following message is transmitted to the host.
Example: driver-id = 871111111117100944, TXD = Z00000000000000871111111117100944 <CR><LF>
