The microwave technology in the 2.45GHz band allows identification at a distance up to 10 meters, even at high speeding passage. The Combi-Booster can be used for two types of Nedap low frequency cards, the thin ISO-card and the thicker XS-card. The firmware of the Combi-Booster also supports 64-bit manchester encoded transponders such as the EM4001.
2 INSTALLATION 2.1 DIMENSIONS The combi-booster is easily mounted on the interior of the car’s windshield by means of suction cups. Users should ensure the visual contact between the combi-booster and any TRANSIT reader is unobstructed with items such as stickers or metallized windshields (see also chapter 2.3 about solar control windshields).
The inserted card is read when the button is pressed. When there is no card present in the combi-booster the driver-id is filled with zeros. As in Mode A, the combi-booster automatically re-checks the inserted card for proper identification every 5 minutes.
Each combi-booster is programmed with the customer code and a unique id number. The same applies for the low frequency card as well. The combi-booster does not verify the customer code of the inserted card, but will forward it to the TRANSIT reader. The TRANSIT reader verifies for both id numbers if the customer code matches the customer code programmed to that reader.
COMBI-BOOSTER 6 MICROWAVE 2.45GHZ RF INTERFACE The combi-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 2.45GHz signal coming from the reader's antenna is modified in such way that it can be recognized by the reader.
The Corporate 1000 format is a 35 bit format with a unique Company ID Code and over 1,000,000 card numbers available for use. The combi-booster does not make any modifications to the format and sends all card information to the reader.
Any Nedap low frequency RFID reader is able to read the vehicle-id of the combi-booster. Refer to the manual of the RFID reader for more details. 7.2 WRITING THE VEHICLE-ID NUMBER The combi-booster's vehicle-id number is normally programmed during production, but can also be programmed by the customer.
Send the following command to the XS110W to read the current operating mode: 01311980?? The combi-booster will respond with a data message to the reader. This data contains the combi- booster's firmware name and version and also the current operating mode. The following replies are...
