5 IDENTIFYING THE BOOSTER WITH A TRANSIT
5.1 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 identification card and activates the Booster’s button.
A beep should indicate that the card was successfully read. A low beep may indicate that reading failed.
n
The TRANSIT reader can identify your card up to a distance of 10 meters (=33 ft).
After 5 seconds the Booster returns into standby mode.
The driver should remove his personal identification card from the Booster when leaving the vehicle.
5.2 READER
OUTPUT
The Prox/Smartcard-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 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 TRANSIT firmware
manuals for more details about the reader communication protocol.
Combi-Booster mode (Vehicle-ID + Driver-ID)
The Booster cannot be identified until the driver inserts his personal identification card and pushes the
Booster’s button. Once the button is pushed the Booster reads the personal identification card and
beeps
n
upon a successful read. Both vehicle-id and driver-id are transmitted to the host system for 5
seconds. Afterwards the Booster automatically deactivates again.
Example: vehicle-id = 123, driver-id = E4947C46, TXD =
Y000000012300000000000000E4947C46
CRLF
If 'Standard-length' is configured, the following message is transmitted to the host.
Example: vehicle-id = 123, driver-id = E4947C46, TXD =
U000000012300E4947C46
CRLF
Booster mode (Only Driver-ID)
The Booster is 'sleeping' until the driver inserts his personal identification card and pushes the Booster’s
button. Once the button is pushed the Booster reads the personal identification card and beeps
n
upon a
successful read. The data is transmitted to the host system for 5 seconds. After that the Booster
automatically deactivates again.
Example: driver-id = 871111111117100944, TXD =
Z00000000000000871111111117100944
CRLF
If 'Standard-length' is configured, the following message is transmitted to the host.
Example: driver-id = 871111111117100944, TXD =
U00871111111117100944
CRLF
Tacho-Booster mode (Vehicle-ID + Driver-ID + Tacho-Counter)
The Booster cannot be identified until the driver inserts his personal identification card and pushes the
Booster’s button. Once the button is pushed the Booster reads the personal identification card and
beeps
n
upon a successful read. Both vehicle-id, driver-id and tacho-counter are transmitted to the host
system for 5 seconds. Afterwards the Booster automatically deactivates again.
Example: vehicle-id = 123, driver-id = E4947C46, tacho-counter = 1234,
TXD =
X000000012300E4947C468000001234
