Identifying the Booster with a TRANSIT
3.1
How to use the Booster
Place the Booster on the inside of the windscreen of your vehicle as described in chapter 2. The driver inserts his
personal ID card and activates the Booster’s button.
A beep should indicate that the card was successfully read. A low beep indicates that card reading failed. See chapter 6
for details about the buzzer indications.
The TRANSIT reader can identify your card up to a distance of 10 meters (=33 ft).
After 5 seconds the Booster returns into sleep mode. The booster will remain active when in 'always-on'-mode.
The driver should remove his personal ID card from the Booster when leaving the vehicle.

Reader output
The Booster is a battery operated passive tag. The information from the tag is sent to the reader by a method called
modulated backscatter. This means that the 2.45GHz signal coming from the reader's antenna is modified in such way
that it can be recognized by the reader.
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 TRANSIT firmware manuals for more details about the reader
communication protocol.
3.2.1
Dual ID mode (Vehicle ID + Driver ID)
The Booster is inactive until the driver inserts his personal ID card and pushes the Booster’s button. Once the button is
pushed the Booster reads the personal ID card and beeps upon a successful read. Both vehicle-id and driver-id are
transmitted to the reader for 5 seconds. Afterwards the Booster automatically deactivates again. The booster will
remain active when in 'always-on'-mode.
Example
vehicle-id = 123, driver-id = E4947C46:
If 'Extended-length (default)' is configured, the following message is transmitted to the host:
TXD =
